Application
• The EQ7 drive is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other purposes.
Fire or an accident could occur.
• The EQ7 drive may not be used for a life-support system or other purposes directly related to the human safety.
• Though the EQ7 drive is manufactured under strict quality control, install safety devices for
applications where serious accidents or property damages are foreseen in relation to the failure of
it.
An accident could occur.
Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
Do not place flammable object nearby.
Doing so could cause fire.
• Inverters with a capacity of 50 HP or above, whose protective structure is IP00 (Open Chassis),
involve a possibility that a human body may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC reactor is connected also involve the same. Install such
inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
Installation
iv
Wiring
• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is
installed in the upstream power supply line in order to avoid the entire power supply system's
shutdown undesirable to factory operation, install a residual-current-operated protective device
(RCD)/earth leakage circuit breaker (ELCB) individually to inverters to break the individual inverter
power supply lines only.
Otherwise, a fire could occur.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
(with overcurrent protection) in the path of each pair of power lines to inverters. Use the
recommended devices within the recommended current capacity.
• Use wires of the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multi-conductor cable for the purpose of running the leads together.
• Do not connect a surge absorber to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or a fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
• Do not connect the power supply wires to output terminals (U, V, and W).
• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals
P(+) and DB.
Doing so could cause fire or an accident.
• In general, the insulation of the control signal wires are not specifically designed to withstand a high
voltage (i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation may break down, which would expose the signal wire to the high voltage of the main circuit. Make sure that the control signal wires
will not come into contact with live conductors of the main circuit.
Doing so could cause an accident or an electric shock.
v
Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the
power and wait at least five minutes for inverters of 40 HP or below, or at least ten minutes for inverters of 50 HP or above. Make sure that the LED monitor and charging lamp are turned
OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage
between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• The inverter, motor and wiring generate electric noise. This may cause the malfunction of nearby sensors and devices. To prevent malfunctioning, implement noise control measures.
Otherwise an accident could occur.
• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter power is ON.
Otherwise, an electric shock could occur.
Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the auto-reset function has been selected, the inverter may automatically restart and drive the
motor depending on the cause of tripping. Design the machinery or equipment so that human safety
is ensured at the time of restarting.
Otherwise, an accident could occur.
• If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or
overload prevention control has been selected, the inverter may operate with acceleration/deceleration or frequency different from the commanded ones. Design the machine so
that safety is ensured even in such cases.
• If any of the protective functions have been activated, first remove the cause. Then, after checking
that the all run commands are set to OFF, release the alarm. If the alarm is released while any run
commands are set to ON, the inverter may supply the power to the motor, running the motor.
Otherwise, an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the inverter automatically restarts running the motor when the power is recovered.
Design the machinery or equipment so that human safety is ensured after restarting.
• If the user configures the function codes wrongly without completely understanding this Instruction
Manual and the EQ7 DRIVE User's Manual, the motor may rotate with a torque or at a speed not
permitted for the machine.
An accident or injuries could occur.
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R, L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
Even if the run command is set to OFF, voltage is output to inverter output terminals U, V, and W if
the servo-lock command is ON.
Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output terminals U, V, and W.
An electric shock may occur.
• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
Operation
vi
Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and
frequency change commands can be assigned to digital input terminals. Depending upon the assignment states of those terminals, modifying the function code setting may cause a sudden
motor start or an abrupt change in speed.
• When the inverter is controlled with the digital input signals, switching run or frequency command
sources with the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and
LE) may cause a sudden motor start or an abrupt change in speed.
• Ensure safety before modifying customizable logic related function code settings (U codes and
related function codes) or turning ON the "Cancel customizable logic" terminal command CLC. Depending upon the settings, such modification or cancellation of the customizable logic may
change the operation sequence to cause a sudden motor start or an unexpected motor operation.
An accident or injuries could occur.
Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least five
minutes for inverters of 40 HP or below, or at least ten minutes for inverters of 50 HP or above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure,
using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+)
and N(-) has dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, an electric shock or injuries could occur.
Never modify the inverter.
Doing so could cause an electric shock or injuries.
Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.

Possible problems
Sample measures
Applications
Highly concentrated sulfurizing gas or other corrosive gases
Corrosive gases cause parts inside the inverter to corrode, resulting in an inverter malfunction.
Any of the following measures may be necessary.
-Mount the inverter in a sealed panel with IP6X or air-purge mechanism.
-Place the panel in a room free from influence of the gases.
Paper manufacturing, sewage disposal, sludge treatment, tire manufacturing, gypsum manufacturing, metal processing, and a particular process in textile factories.
A lot of conductive dust or foreign material (e.g., metal powders or shavings, carbon fibers, or carbon dust)
Entry of conductive dust into the inverter causes a short circuit.
Any of the following measures may be necessary.
-Mount the inverter in a sealed panel.
-Place the panel in a room free from influence of the conductive dust.
Wiredrawing machines, metal processing, extruding machines, printing presses, combustors, and industrial waste treatment.
A lot of fbrous or paper dust
Fibrous or paper dust accumulated on the heat sink lowers the cooing effect. Entry of dust into the inverter causes the electronic circuitry to malfunction.
Any of the following measures may be necessary.
-Mount the inverter in a sealed panel that shuts out dust.
-Ensure a maintenance space for periodical cleaning of the heat sink in panel engineering design.
-Employ external cooling when mounting the inverter in a panel for easy maintenance and perform periodical maintenance.
Textile manufacturing and paper manufacturing. High humidity or dew condensation
In an environment where a humidifier is used or where the air conditioner is not equipped with a dehumidifier, high humidity or dew condensation results, which causes a short­circuiting or malfunction of electronic circuitry inside the inverter.
- Put a heating module such as a space heater in the panel.
Outdoor installation. Film manufacturing line, pumps and food processing.
V bration or shock exceeding the specified level
If a large vibration or shock exceeding the specified level is applied to the inverter, for example, due to a carrier running on seam joints of rails or blasting at a construction site, the inverter structure gets damaged.
-Insert shock-absorbing materials between the mounting base of the inverter and the panel for safe mounting.
Installation of an inverter panel on a carrier or self­propelled machine. Ventilating fan at a construction site or a press machine.
Fumigation for export packaging
Halogen compounds such as methyl bromide used in fumigation corrodes some parts inside the inverter.
-When exporting an inverter built in a panel or equipment, pack them in a previously fumigated wooden crate.
-When packing an inverter alone for export, use a laminated veneer lumber (LVL).
Exporting.
Mounting of the EQ7 drive is extremely important for accessibility as well as for the environment. Various EQ7 drive models are available and the mounting dimensions (footprint) may be different. Install the EQ7 drive in an environment that satisfies the requirements.
TECO-Westinghouse Motor Company strongly recommends installing inverters in a panel for safety reasons, in particular, when installing the ones that have an enclosure rating of IP00.
When installing the EQ7 drive in a place out of the specified environmental requirements, it is necessary to derate the
inverter or consider the panel engineering design suitable for the special environment or the panel installation
location. For details consult your TECO-Westinghouse Motor Company representative. The special environments listed below require using the specially designed panel or considering the panel installation location.

When a motor protective thermal O/L relay is inserted between the inverter and the motor, the thermal O/L relay may malfunction (particularly in the 460 V series), even when the cable length is 165 ft (50 m) or less. To correct, insert a filter or reduce the carrier frequency. (Use function code F26 "Motor sound".)
For the vector control mode, wiring length is 328 ft (100 m) or less.
The storage environment in which the inverter is stored after purchase is different from the operation environment. For details, refer to the EQ7 DRIVE User's Manual, Chapter 2.
Wiring precautions
(1) Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions. (2) Place the control circuit wires inside the inverter to keep them away from the live parts of the main circuit (such as the terminal block of the main circuit). (3) If more than one motor is to be connected to a single inverter, the wiring length should be the sum of the length of the wires to the motors. (4) Drive output terminals (U, V, W)
1) Connect these terminals to a 3-phase motor in the correct phase sequence. If the direction of motor rotation is
incorrect, exchange any two of the U, V, and W phases.
2) Do not connect a power factor correction capacitor or surge suppressor to the inverter output.
3) If the cable from the inverter to the motor is very long, a high-frequency current may be generated by stray
capacitance between the cables and result in an overcurrent trip of the inverter, an increase in leakage current,
or a reduction in current indication precision.
When a motor is driven by a PWM-type inverter, the motor terminals may be subject to surge voltage
generated by inverter element switching. If the motor cable (with 460 V series motors, in particular) is particularly
long, surge voltage will deteriorate motor insulation. To prevent this, use the following guidelines:
* For this case the cable length is determined by secondary effects and not voltage spiking.
(5) When an output circuit filter is inserted in the secondary circuit or the wiring between the inverter and the motor is long, a voltage loss occurs due to reactance of the filter or wiring so that the insufficient voltage may cause output current oscillation or a lack of motor output torque. To avoid it, select the constant torque load by setting the function code F37 (Load Selection/Auto Torque Boost/Auto Energy Saving Operation 1) to "1" and keep the inverter output voltage at a higher level by configuring H50/H52 (Non-linear V/f Pattern, Frequency) and H51/H53 (Non-linear V/f Pattern, Voltage).

For selecting DCR models, refer to Chapter 11 "SPECIFICATIONS."
(1) Phase-advancing capacitors for power factor correction
Do not mount a phase-advancing capacitor for power factor correction in the inverter's input (primary) or output
(secondary) circuit. Mounting it in the input (primary) circuit takes no effect. To correct the inverter power factor,
use an optional DC reactor (DCR). Mounting it in the output (secondary) circuit causes an overcurrent trip,
disabling operation.
An overvoltage trip that occurs when the inverter is stopped or running with a light load is assumed to be due to
surge current generated by open/close of phase-advancing capacitors in the power system. An optional DC/AC
reactor (DCR/ACR) is recommended as a measure to be taken at the inverter side.
Input current to an inverter contains a harmonic component that may affect other motors and phase-advancing
capacitors on the same power supply line. If the harmonic component causes any problems, connect an optional
DCR/ACR to the inverter. In some cases, it is necessary to insert a reactor in series with the phase-advancing
capacitors.
(2) Power supply lines (Application of a DC/AC reactor)
Use an optional DC reactor (DCR) when the capacity of the power supply transformer is 500 kVA or more and is
10 times or more the inverter rated capacity or when there are thyristor-driven loads. If no DCR is used, the
percentage-reactance of the power supply decreases, and harmonic components and their peak levels increase.
These factors may break rectifiers or capacitors in the converter section of the inverter, or decrease the
capacitance of the capacitors.
If the input voltage unbalance rate is 2% to 3%, use an optional AC reactor (ACR).
(3) DC reactor (DCR) for correcting the inverter input power factor (for suppressing harmonics)
To correct the inverter input power factor (to suppress harmonics), use an optional DCR. Using a DCR increases
the reactance of inverter’s power source so as to decrease harmonic components on the power source lines and
correct the power factor of the inverter.
(4) PWM converter for correcting the inverter input power factor
Using a PWM converter (High power-factor, regenerative PWM converter) corrects the inverter power factor up to
nearly 100%. When combining an inverter with a PWM converter, disable the main power down detection by
setting the function code H72 to "0." If the main power loss detection is enabled (H72 = 1 by factory default), the
inverter interprets the main power as being shut down, ignoring an entry of a run command.

breaker (ELCB) Install a recommended MCCB or RCD/ELCB (with overcurrent protection) in the primary circuit of the inverter to protect the wiring. Since using an MCCB or RCD/ELCB with a lager capacity than recommended ones breaks the protective coordination of the power supply system, be sure to select recommended ones. Also select ones with short-circuit breaking capacity suitable for the power source impedance.

If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the
upstream power supply line in order to avoid the entire power supply system's shutdown undesirable to factory
operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to inverters to break the individual inverter power supply lines only.
Otherwise, a fire could occur.

Leakage Circuit Breaker (ELCB)
(6) Magnetic contactor (MC) in the inverter input (primary) circuit Avoid frequent ON/OFF operation of the magnetic contactor (MC) in the input circuit; otherwise, the inverter failure
may result. If frequent start/stop of the motor is required, use FWD/REV terminal signals or the / keys on the
inverter's keypad.
The frequency of the MC's ON/OFF should not be more than once per 30 minutes. To assure 10 -year or longer
service life of the inverter, it should not be more than once per hour.
1-7
• From the system's safety point of view, it is recommended to employ such a sequence that shuts down
the magnetic contactor (MC) in the inverter input circuit with an alarm output signal ALM issued on inverter's programmable output terminals. The sequence minimizes the secondary damage even if the
inverter breaks.
When the sequence is employed, connecting the MC's primary power line to the inverter's auxiliary
control power input makes it possible to monitor the inverter's alarm status on the keypad.
• The breakdown of a braking unit or misconnection of an external braking resistor may trigger that of the
inverter's internal parts (e.g., charging resistor). To avoid such a breakdown linkage, introduce an MC and configure a sequence that shuts down the MC if a DC link voltage establishment signal is not
issued within three seconds after the MC is switched on.
For the braking transistor built-in type of inverters, assign a transistor error output signal DBAL on
inverter's programmable output terminals to switch off the MC in the input circuit.
(7) Magnetic contactor (MC) in the inverter output (secondary) circuit If a magnetic contactor (MC) is inserted in the inverter's output (secondary) circuit for switching the motor to a
commercial power or for any other purposes, it should be switched on and off when both the inverter and motor
are completely stopped. This prevents the contact point from getting rough due to a switching arc of the MC. The
MC should not be equipped with any main circuit surge killer.
Applying a commercial power to the inverter's output circuit breaks the inverter. To avoid it, interlock the MC on the
motor's commercial power line with the one in the inverter output circuit so that they are not switched ON at the
same time.
(8) Surge absorber/surge killer Do not install any surge absorber or surge killer in the inverter's output (secondary) lines.
Noise reduction
If noise generated from the inverter affects other devices, or that generated from peripheral equipment causes the
inverter to malfunction, follow the basic measures outlined below. (1) If noise generated from the inverter affects the other devices through power wires or grounding wires:
- Isolate the grounding terminals of the inverter from those of the other devices.
- Connect a noise filter to the inverter power wires.
- Isolate the power system of the other devices from that of the inverter with an insulated transformer.
- Decrease the inverter's carrier frequency (F26).

(2) If induction or radio noise generated from the inverter affects other devices:
Problem
Measures
An earth leakage circuit breaker* that is connected to the input (primary) side has tripped. *With overcurrent protection
1) Decrease the carrier frequency.
2) Make the wires between the inverter and motor shorter.
3) Use an earth leakage circuit breaker with lower sensitivity than the one currently used.
4) Use an earth leakage circuit breaker that features measures against the high frequency current component.
An external thermal relay was activated.
1) Decrease the carrier frequency.
2) Increase the current setting of the thermal relay.
3) Use the electronic thermal overload protection built in the inverter, instead of the external thermal relay.
- Isolate the main circuit wires from the control circuit wires and other device wires.
- Put the main circuit wires through a metal conduit pipe, and connect the pipe to the ground near the inverter.
- Install the inverter into the metal panel and connect the whole panel to the ground.
- Connect a noise filter to the inverter's power wires.
- Decrease the inverter's carrier frequency (F26). (3) When implementing measures against noise generated from peripheral equipment:
- For inverter's control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires, connect the shield of the shielded wires to the common terminals of the control circuit.
- Connect a surge absorber in parallel with magnetic contactor's coils or other solenoids (if any).
Leakage current
A high frequency current component generated by insulated gate bipolar transistors (IGBTs) switching on/off inside the
inverter becomes leakage current through stray capacitance of inverter input and output wires or a motor. If any of the
problems listed below occurs, take an appropriate measure against them.
Selecting inverter capacity
(1) To drive a general-purpose motor, select an inverter according to the nominal applied motor rating listed in the
standard specifications table. When high starting torque is required or quick acceleration or deceleration is
required, select an inverter with one rank higher capacity than the standard.
(2) Special motors may have larger rated current than general-purpose ones. In such a case, select an inverter that
meets the following condition.
Inverter rated current > Motor rated current
1-9
1.3 Precautions in running inverters
Precautions for running inverters to drive motors or motor-driven machinery are described below.
Motor temperature
When an inverter is used to run a general-purpose motor, the motor temperature becomes higher than when it is operated with a commercial power supply. In the low-speed range, the motor cooling effect will be weakened, so decrease the output torque of the motor when running the inverter in the low-speed range.
Motor noise
When a general-purpose motor is driven by an inverter, the noise level is higher than that when it is driven by a
commercial power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or higher can
also result in higher noise level.
Machine vibration
When an inverter-driven motor is mounted to a machine, resonance may be caused by the natural frequencies of the motor-driven machinery. Driving a 2-pole motor at 60 Hz or higher may cause abnormal vibration. If it happens, do any of the following:
- Consider the use of a rubber coupling or vibration-proof rubber.
- Use the inverter's jump frequency control feature to skip the resonance frequency zone(s).
- Use the vibration suppression related function codes that may be effective. For details, refer to the description of
H80 in Chapter 4 "FUNCTION CODES" of the user manual.
1.4 Precautions in using special motors
When using special motors, please read the following section:
Explosion-proof motors
When driving an explosion-proof motor with an inverter, use a combination of a motor and an inverter that has been approved in advance.
Submersible motors and pumps
These motors have a larger rated current than general-purpose motors. Select an inverter with rated output current that is greater than that of the motor. These motors differ from general-purpose motors in thermal characteristics. Decrease the thermal time constant of the electronic thermal overload protection to match the motor rating.
Brake motors
For motors equipped with parallel-connected brakes, their power supply for braking must be supplied from the inverter
input (primary) circuit. If the power supply for braking is mistakenly connected to the inverter's output (secondary) circuit, the brake may not work when the inverter output is shut down. Do not use inverters for driving motors
equipped with series-connected brakes.
Geared motors
If the power transmission mechanism uses an oil-lubricated gearbox or speed changer/reducer, then continuous operation at low speed may cause poor lubrication. Avoid such operation.
Synchronous motors
It is necessary to take special measures suitable for this motor type. Contact your TECO-Westinghouse Motor Company representative for details.
Single-phase motors Single-phase motors are not suitable for inverter-driven variable speed operation.
1-10
High-speed motors
If the reference frequency is set to 120 Hz or higher to drive a high-speed motor, test-run the combination of the inverter and motor beforehand to check it for the safe operation.
Precautions for use on single-phase power
An inverter is a device that converts alternating current of the input line to direct current via the ac-to-dc rectifier and then converts it to alternating current via the dc-to-ac switching inverter circuit in order to output the required alternating current. The EQ7 drive is designed to connect to the three-phase power and this manual stipulates the specifications for the use on the three-phase power. If the inverter designed for connection to three-phase power runs on single-phase power, ripples (voltage fluctuation) on the DC link bus voltage rectified from the input power become larger than those in the inverter running on three­phase power. The DC-voltage ripple affects the inverter output; that is, ripples could be superimposed on the output voltage or current, making control hard. Accordingly, the inverter may not work in full performance or function correctly. To use the EQ7 drive on single-phase power, therefore, you need to take the following into account.
Output current
Select the inverter capacity to keep the output current within the specified level, referring to chapter 11. Output current exceeding the limit extremely increases voltage ripples on the DC link bus, impeding normal operation or resulting in an inverter breakdown.
Wiring
When connecting 230 V inverters of 60 HP or above or 460 V ones of 125 HP or above to single-phase power, use L1 and L3 phases since cooling fans and magnetic contactors inside the inverter are supplied with power via L1 and L3. Using L2 does not work cooling fans or magnetic contactors, causing abnormal heat, in the worst case, resulting in an inverter breakdown.
Connecting peripheral devices
For the specifications of circuit breakers and fuses to apply, refer to pages 1-6 and 1-7.
Configuring function codes
(1) Cancel the input phase loss protection of the protection/maintenance function with function code H98 (Bit 1 = 0).
This is because the inverter judges single-phase power as a phase loss. (2) Limit the drive mode to the VT / CT-V mode (Function code F80 = 0 or 1). (3) Do not use "Vector control without speed sensor" or torque control. (Function codes F42 5, H18 = 0) (4) "V/f control with slip compensation inactive" is recommended (F42 = 0). Any other drive control calculates the
motor model using the motor parameters inside the inverter. As ripples on the DC link bus voltage become larger,
therefore, calculation causes some errors so that the inverter may not provide the desired performance. Consider
this problem before use. In particular, when using "Vector control with speed sensor" (F42 = 6), dancer control
(J01 = 3), or brake signals (J68, J69, J70, etc.), assure the operation and safety of those speed sensors.

Otherwise, a fire could occur.
(2) Clearances
Ensure that the minimum clearances indicated in Figure 2.1 and Table 2.3 are maintained at all times. When mounting the inverter in the panel of your system, take extra care with ventilation inside the panel as the surrounding temperature easily rises. Do not mount the inverter in a small panel with poor ventilation.
When mounting two or more inverters
When mounting two or more inverters in the same unit or panel, install them side by side. When one must be mounted above the other, be sure to separate them with a partition plate, or the like, so that any heat radiating from an inverter will not affect the one/s above.
As long as the surrounding temperature is 40°C (104°F) or lower, inverters of 40 HP or below can be mounted side by side without any clearance between them.

(Note 1) When inverters (40 HP or below) are mounted side-by-side without any clearance between them, the surrounding temperature should be within the range from -10 to +40 C (14 to 104 F). This specification also applies to the inverters (40 HP) equipped with a NEMA1 kit.
(Note 2) Do not install the inverter in an environment where it may be exposed to lint, cotton waste or moist dust or dirt which will clog the heat sink of the inverter. If the inverter is to be used in such an environment, install it in a dustproof panel.
(Note 3) If you use the inverter in an altitude above 3300 ft (1000 m), you should apply an output current derating factor as listed in Table 2.2.

When employing external cooling
In external cooling, the heat sink, which dissipates about 70% of the total heat (total loss) generated into air, is situated outside the equipment or the panel. The external cooling, therefore, significantly reduces heat radiating inside the equipment or panel.
To employ external cooling for inverters (except DCR built-in type) of 40 HP or below, use the mounting adapter for external cooling (option); for those of 50 HP or above, simply change the positions of the mounting bases.
The DCR built-in type of 40 HP or below cannot employ external cooling.
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.
Otherwise, a fire or accident could occur.

To utilize external cooling for inverters of 50 HP or above, change the positions of the top and bottom mounting bases from the edge to the center of the inverter as shown in Figure 2.3.
Screws differ in size and count for each inverter. Refer to the table below.
Table 2.4 Screw Size, Count and Tightening Torque
1) Remove all base fixing screws and case fixing screws from the top of the inverter.
2) Move the top mounting base to the center of the inverter and secure it to the case fixing screw holes with the base fixing screws. (After changing the position of the top mounting base, some screws may be left unused.)
3) Remove the base fixing screws from the bottom of the inverter, move the bottom mounting base to the center of the inverter, and secure it with the base fixing screws, just as in step 2). (Inverters of 450 HP or below have no case fixing screws on the bottom.)
2-2
When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or accident could occur.

* Using wires exceeding the recommended sizes may lift the front cover
depending upon the number of wires used, impeding keypad's normal operation.
2.3.3 Wiring precautions
Follow the rules below when performing wiring for the inverter. (1) Make sure that the source voltage is within the rated voltage range specified on the nameplate. (2) Be sure to connect the three-phase power wires to the main circuit power input terminals L1/R, L2/S and L3/T of
the inverter. If the power wires are connected to other terminals, the inverter will be damaged when the power is turned ON.
(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters and to reduce electric
noise.
(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to ensure a reliable
connection.
(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the main circuit, and control
circuit wiring as far away as possible from each other.
(6) After removing a screw from the main circuit terminal block, be sure to restore the screw even if no wire is
connected.
(7) Use the wiring guide to separate wiring. For inverters of 5 HP or below, the wiring guide separates the main circuit
wires and the control circuit wires. For those of 7.5 to 40 HP, it separates the upper and lower main circuit wires, and control circuit wires. Be careful about the wiring order.
Preparing for the wiring guide
Inverters of 20 to 40 HP (three-phase, 230 V series) are sometimes lacking in wiring space for main circuit wires depending upon the wire materials used. To assure a sufficient wiring space, remove the clip-off sections (see below) as required with a nipper. Note that the enclosure rating of IP20 may not be ensured when the wiring guide itself is removed to secure a space for thick main circuit wiring.
2-8
Before removal of clip-off sections After removal of clip-off sections
Wiring Guide (e.g. EQ7-4025-C)
(8) In some types of inverters, the wires from the main circuit terminal block cannot be routed straight into the terminal.
Route such wires as shown below so that the front cover can be reinstalled.
(9) For inverters of 900 and 1000 HP, two L2/S input terminals are arranged vertically to the terminal block. When
connecting wires to these terminals, use the bolts, washers and nuts that come with the inverter, as shown below.
2-9
When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current capacity.
Be sure to use wires in the specified size.
Tighten terminals with specified torque.
Otherwise, a fire could occur.
When there is more than one combination of an inverter and motor, do not use a multiconductor cable for the purpose of running the leads together.
Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
Ground the inverter in compliance with the national or local electric code.
Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or fire could occur.
Qualified electricians should carry out wiring.
Be sure to perform wiring after turning the power OFF.
Otherwise, electric shock could occur.
Be sure to perform wiring after installing the inverter unit.
Otherwise, electric shock or injuries could occur.
Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
Do not connect the power source wires to inverter output terminals (U, V, and W).
Doing so could cause fire or an accident.

2.3.4 Wiring of main circuit terminals and grounding terminals
This section shows connection diagrams with the Enable input function used. SINK mode input by factory default
2-11
When there is more than one combination of an inverter and motor, do not use a multi-conductor cable for the purpose of running the leads together.
*1 Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device
(RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection function) in the primary circuit of the inverter to protect wiring. Ensure that the circuit breaker capacity is equivalent to or lower than the recommended capacity.
*2 Install a magnetic contactor (MC) for each inverter to separate the inverter from the power supply, apart from the
MCCB or RCD/ELCB, when necessary. Connect a surge absorber in parallel when installing a coil such as the MC or solenoid near the inverter.
*3 The R0 and T0 terminals are provided for inverters with a capacity of 2 HP or above.
To retain an alarm output signal ALM issued on inverter's programmable output terminals by the protective function or to keep the keypad alive even if the main power has shut down, connect these terminals to the power supply lines. Without power supply to these terminals, the inverter can run.
*4 Normally no need to be connected. Use these terminals when the inverter is equipped with a high power-factor,
regenerative PWM converter (RHC series).
*5 When connecting an optional DC reactor (DCR), remove the jumper bar from the terminals P1 and P(+).
EQ7-2100-C/EQ7-4100-C and larger HP models require a DCR (packed with the EQ7) to be connected.
Use a DCR when the capacity of the power supply transformer exceeds 500 kVA and is 10 times or more the
inverter rated capacity, or when there are thyristor-driven loads in the same power supply line.
*6 EQ7-2015-C/EQ7-4015-C and smaller have a built-in braking resistor (DBR) between the terminals P(+) and DB. When connecting an external braking resistor (DBR), be sure to disconnect the built-in one.
*7 A grounding terminal for a motor. Use this terminal if needed. *8 For control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires, connect the
shield of them to the common terminals of the control circuit. To prevent malfunction due to noise, keep the control circuit wiring away from the main circuit wiring as far as possible (recommended: 10 cm/3.9 inches or more). Never install them in the same wire duct. When crossing the control circuit wiring with the main circuit wiring, set them at right angles.
*9 The connection diagram shows factory default functions assigned to digital input terminals [X1] to [X7], [FWD] and
[REV], transistor output terminals [Y1] to [Y4], and relay contact output terminals [Y5A/C] and [30A/B/C].
*10 Switching connectors in the main circuits. For details, refer to "Instruction manual section 2.3.4 Switching
connectors" later in this section.
*11 Slide switches on the control printed circuit board (control PCB). Use these switches to customize the inverter
operations. For details, refer to Section 2.3.6 "Setting up the slide switches."
*12 When the Enable input function is not to be used, keep terminals [EN1]-[PLC] and terminals [EN2]-[PLC]
short-circuited using jumper wires. For opening and closing the hardware circuit between terminals [EN1] and [PLC] and between [EN2] and [PLC], use safety components such as safety relays and safety switches that comply with EN954-1 or EN ISO13849-1 Category 3 or higher.
*13 To bring the inverter into compliance with the European Standard, Low Voltage Directive EN61800-5-1, be sure to
insert the specified fuse in the primary circuit of the inverter.
Primary grounding terminal ( G) for inverter enclosure
Two grounding terminals ( G) are not exclusive to the power supply wiring (primary circuit) or motor wiring (secondary circuit). Be sure to ground either of the two grounding terminals for safety and noise reduction. The inverter is designed for use with safety grounding to avoid electric shock, fire and other disasters.
The grounding terminal for inverter enclosure should be grounded as follows:
1) Ground the inverter in compliance with the national or local electric code.
2) Use a thick grounding wire with a large surface area and keep the wiring length as short as possible.
Inverter output terminals U, V, and W and secondary grounding terminals ( G) for motor
Inverter’s output terminals should be connected as follows:
1) Connect the three wires of the 3-phase motor to terminals U, V, and W, aligning the phases each other.
2) Connect the secondary grounding wire to the grounding terminal ( G).
2-12
The wiring length should be 33 ft (10 m) or below.
Do not remove the jumper bar when a DCR is not used.
The EQ7-2100-C / EQ7-4100-C and higher types come with a DCR. Be sure to connect the DCR.
If a PWM converter is connected to the inverter, no DCR is required.
Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.

2) Connect an optional DCR to those terminals.
DC braking resistor terminals P(+) and DB (for inverters of 40 HP or below)
For inverters of 15 HP or below, if the capacity of the built-in DC braking resistor (DBR) is insufficient since the inverter undergoes frequent start/stop or heavy inertial load, mount an optional external DC braking resistor (DBR) with a larger capacity to increase the braking capability, using the following steps. Before mounting the external DBR, remove the built-in DBR.
1) For inverters of 0.5 to 5 HP, disconnect the wiring of the built-in DBR from terminals P(+) and DB; for those of 7.5 to 15 HP, disconnect the wiring from terminal DB and the internal relay terminal (see the figure below).
Insulate the terminals of the disconnected wires with insulating tape or other materials.
2) Connect an optional DBR to terminals P(+) and DB.
The internal relay terminal on inverters of 7.5 to 15 HP is left unused.
3) Arrange the DBR and inverter so that the wiring length comes to 16 ft (5 m) or less and twist the two DBR wires or route them together in parallel.

so that the wiring length comes to 33 ft (10 m) or less and twist the two wires or route them together in parallel. For details about the wiring, refer to the Braking Unit Instruction Manual.
2) Connecting other external devices
A DC link bus of other inverter(s) or a PWM converter is connectable to these terminals.
Switching connectors
Power switching connectors (CN UX) (on inverters of 125 HP or above for 460 V)
Inverters of 125 HP or above for 460 V are equipped with a set of switching connectors (male) which should be configured according to the power source voltage and frequency. By factory default, a jumper (female connector) is set to U1. If the power supply to the main power inputs (L1/R, L2/S, L3/T) or the auxiliary fan power input terminals (R1, T1) matches the conditions listed below, change the jumper to U2.

The standard EQ7 series accepts DC-linked power input in combination with a PWM converter. Inverters of 60 HP or above for 230 V and those of 125 HP or above for 460 V, however, contain AC-driven components such as AC fans. To supply AC power to those components, exchange the CN R and CN W connectors as shown below and connect the AC power line to the auxiliary fan power input terminals (R1, T1).

Figure 2.7 Inserting/Removing the Jumpers
To remove each of the jumpers, pinch its upper side between your fingers, unlock its fastener, and pull it up.
When mounting it, fit the jumper over the connector until it snaps into place.
It is recommended to insert a manually operable magnetic contactor (MC) that allows you to disconnect the inverter from the power supply in an emergency (e.g., when the protective function is activated), preventing a failure or accident from causing secondary disasters.
When introducing a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB), connect its output (secondary) side to terminals R0 and T0. Connecting its input (primary) side to those terminals causes the RCD/ELCB to malfunction since the input power voltage to the inverter is three-phase but the one to terminals R0 and T0 is single-phase. To avoid such problems, be sure to insert an isolation transformer or auxiliary B contacts of a magnetic contactor in the location shown in Figure 2.8.
Figure 2.8 Connection Example of Residual-current-operated Protective Device (RCD)/
Earth Leakage Circuit Breaker (ELCB)
Main circuit power input terminals L1/R, L2/S, and L3/T (three-phase input)
The three-phase input power lines are connected to these terminals.
1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned OFF
before wiring the main circuit power input terminals.
2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T) to the input terminals of the inverter via an
MCCB or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)*, and an MC if necessary.
It is not necessary to align phases of the power supply wires and the input terminals of the inverter with each other.
* With overcurrent protection
Auxiliary control power input terminals R0 and T0 (on inverters of 2 HP or above)
In general, the inverter runs normally without power supplied to the auxiliary control power input terminals R0 and T0. If the inverter main power is shut down, however, no power is supplied to the control circuit so that the inverter cannot issue a variety of output signals or display on the keypad.
To retain an alarm output signal ALM issued on inverter's programmable output terminals by the protective function or to keep the keypad alive even if the main power has shut down, connect the auxiliary control power input terminals R0 and T0 to the power supply lines. If a magnetic contactor (MC) is installed in the inverter's primary circuit, connect the primary circuit of the MC to these terminals R0 and T0.
Terminal rating: 200 to 240 VAC, 50/60 Hz, Maximum current 1.0 A (230 V series with 40 HP or below)
200 to 230 VAC, 50/60 Hz, Maximum current 1.0 A (230 V series with 50 HP or above) 380 to 480 VAC, 50/60 Hz, Maximum current 0.5 A (460 V series)
2-16
When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals R0 and T0. If a PWM is to be connected, insert an isolation transformer or auxiliary B contacts of a magnetic contactor at the power supply side. For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.
Figure 2.9 Connection Example of PWM Converter
Auxiliary fan power input terminals R1 and T1
Inverters of 60 HP or above for 230 V and those of 125 HP or above for 460 V are equipped with terminals R1 and T1. Only if the inverter works with the DC-linked power input whose source is a PWM converter, these terminals are used to feed AC power to the fans, while they are not used in any power system of ordinary configuration.
In this case, set up the fan power supply switching connectors (CN R and CN W). Terminal rating:
200 to 220 VAC/50 Hz, 200 to 230 VAC/60 Hz, Maximum current 1.0 A (230 V series with 60 HP or above) 380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 1.0 A (460 V series with 125 to 800 HP) 380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 2.0 A (460 V series with 900 and 1000 HP)
2-17
In general, the covers of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into contact with live conductors of the main circuit.
Failure to observe these precautions could cause electric shock or an accident.
Noise may be emitted from the inverter, motor and wires. Take appropriate measures to prevent the nearby sensors and devices from malfunctioning due to such noise.
An accident could occur.

Input impedance: 22k
The maximum input is 15 VDC, however, the voltage higher than 10 VDC is handled
as 10 VDC.
Inputting a bipolar analog voltage (0 to 10 VDC) to terminal [V2] requires setting function code C45 to "0."

- Since low level analog signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 66 ft (20 m)) and use shielded wires. In principle, ground the shielded sheath of wires; if effects of external inductive noises are considerable, connection to terminal [11] may be effective. As shown in Figure 2.11, be sure to ground the single end of the shield to enhance the shield effect.
- Use a twin-contact relay for low level signals if the relay is used in the control circuit. Do not connect the relay's contact to terminal [11].
- When the inverter is connected to an external device outputting the analog signal, the external device may malfunction due to electric noise generated by the inverter. If this happens, according to the circumstances, connect a ferrite core (a toroidal core or equivalent) to the device outputting the analog signal or connect a capacitor having the good cut-off characteristics for high frequency between control signal wires as shown in Figure 2.12.
- Do not apply a voltage of +7.5 VDC or higher to terminal [C1]. Doing so could damage the internal control circuit.

For inputting a pulse train through the digital input terminal [X7]
• Inputting from a pulse generator with an open collector transistor output Stray capacity on the wiring between the pulse generator and the inverter may disable transmission of the pulse
train. As a countermeasure against this problem, insert a pull-up resistor between the open collector output signal (terminal [X7]) and the power source terminal (terminal [PLC]) if the switch selects the SINK mode input; insert a pull-down resistor between the output signal and the digital common terminal (terminal [CM]) if the switch selects the SOURCE mode input.
A recommended pull-up/down resistor is 1k 2 W. Check if the pulse train is correctly transmitted because stray capacity is significantly affected by the wire types and wiring conditions.

- Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions.
- Fix the control circuit wires with a cable tie inside the inverter to keep them away from the live parts of the main circuit (such as the terminal block of the main circuit).
Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at least five minutes for inverters of 40 HP or below, or at least ten minutes for those of 50 HP or above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

Make sure to follow good wiring practices and all applicable codes. Ensure that the equipment is grounded properly as shown.
DANGER, LETHAL VOLTAGES ARE PRESENT- Before applying power to the EQ7 drive, ensure that the terminal cover is fastened and all wiring connections are secure. After the power has been turned OFF, wait at least ten minutes until the charge indicator extinguishes completely before touching any wiring, circuit boards or components.

*1. Refer to page 2-11 & 2-12 for connecting a DC reactor from the terminals P1 and P(+). *2. Make sure the drive is properly sized for single phase input (consult factory).
(Refer to Table 2.6 Recommended Wire Sizes in this manual).
Never connect power supply wires to the EQ7 drive output terminals U, V, and W. Doing so and turning
the power ON damages the inverter.
Be sure to connect the grounding wires of the EQ7 drive and the motor to the ground electrodes.
Otherwise, an electric shock could occur.
Check the following before powering on the EQ7 drive.
1) Check that the wiring is correct. Especially check the wiring to the EQ7 drive input terminals L1/R, L2/S and L3/T and output terminals U, V, and W. Also check that the grounding wires are connected to the grounding terminals ( G) correctly. See Figure 2.23.
2) Check the control circuit terminals and main circuit terminals for short circuits or ground faults.
3) Check for loose terminals, connectors and screws.
4) Check that the motor is separated from mechanical equipment.
5) Make sure that all switches of devices connected to the inverter are turned OFF. Powering on the inverter with any of those switches being ON may cause an unexpected motor operation.
6) Check that safety measures are taken against runaway of the equipment. Also ensure that all safety guards are in place to prevent human injury.

The EQ7 identifies abnormal states in two categories--Alarm and Light alarm. If the former occurs, the inverter immediately trips; if the latter occurs, the appears on the LED monitor and the "L-ALARM" appears blinking in the operation guide area on the LCD monitor, but the inverter continues to run without tripping.
Which abnormal states are categorized as a light alarm ("Light alarm" object) should be defined with function codes H81
and H82 beforehand.
Assigning the LALM signal to any one of the digital output terminals with any of function codes E20 to E24 and E27
(data = 98) enables the inverter to output the LALM signal on that terminal upon occurrence of a light alarm.
Figure 3.6 Display of Light Alarm
For details of the light alarms, refer to Chapter 10 "TROUBLESHOOTING."
How to check a light alarm
If a light alarm occurs, the appears on the LED monitor. To check the current light alarm, enter Programming mode
by pressing the key and select LALM1 on Menu #5 "Maintenance Information." It is also possible to check the last three light alarms by selecting LALM2 (last) to LALM4 (3rd last).
For details of the menu transition of the maintenance information, refer to Section 3.4.6 "Reading maintenance
information."
How to remove the current light alarm
After checking the current light alarm, to switch the LED monitor from the indication back to the running status
display (e.g., output frequency), press the key in Running mode. If the light alarm has been removed, the "L-ALARM" disappears and the LALM output signal turns OFF. If not (e.g. DC
fan lock), the on the LED monitor disappears so that normal monitoring becomes available, but the "L-ALARM" remains displayed on the LCD monitor (as shown below) and the LALM output signal remains ON.

4.1 Function Code Tables
Function codes enable the EQ7 series of inverters to be set up to match your system requirements. Each function code consists of a 3-letter alphanumeric string. The first letter is an alphabet that identifies its group and the following two
letters are numerals that identify each individual code in the group. The function codes are classified into 13 groups: Fundamental Functions (F codes), Extension Terminal Functions (E codes), Control Functions (C codes), Motor 1 Parameters (P codes), High Performance Functions (H codes), Motor 2 (A codes), Application Functions 1 and 2 (J and d), Link Functions (y codes) and Option Functions (o codes). To determine the property of each function code, set data to the function code.
This manual does not contain the descriptions of Option Function (o codes). For Option Function (o codes), refer to the instruction manual for each option.
The following descriptions supplement those given in the function code tables on the following pages.
Changing, validating, and saving function code data when the inverter is running
Function codes are indicated by the following based on whether they can be changed or not when the inverter is running:
Copying data
The keypad is capable of copying of the function code data stored in the inverter's memory into the keypad's memory (refer to Menu #7 "Data copying" in Programming mode). With this feature, you can easily transfer the data saved in a source inverter to other destination inverters.
If the specifications of the source and destination inverters differ, some code data may not be copied to ensure safe operation of your power system. Whether data will be copied or not is detailed with the following symbols in the "Data copying" column of the function code tables given on the following pages.
Y: Will be copied unconditionally. Y1: Will not be copied if the rated capacity differs from the source inverter. Y2: Will not be copied if the rated input voltage differs from the source inverter. N: Will not be copied. (The function code marked with "N" is not subject to the Verify operation, either.)
For details of copying operation, refer to the User Manual Chapter 3, Section 3.4.9.
Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for the programmable, digital input and output terminals by setting the function code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to active-OFF signal (the function takes effect if the terminal is opened.) in the negative logic system. Active-ON signals can be switched to active-OFF signals, and vice versa, with the function code data setting, except some signals.
To set the negative logic system for an input or output terminal, enter data of 1000s (by adding 1000 to the data for the normal logic) in the corresponding function code.
Example: "Coast to a stop" command BX assigned to any of digital input terminals [X1] to [X7] using any of function codes E01 through E07

The EQ7 is a general-purpose inverter whose operation is customized by frequency-basis function codes, like conventional inverters. Under the speed-basis drive control, however, the control target is a motor speed, not a frequency, so convert the frequency to the motor speed according to the following expression.
Motor speed (r/min) = 120 Frequency (Hz) Number of poles
The EQ7 runs under any of the following drive controls. Some function codes apply exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N (Not applicable) in the "Drive control" column in the function code tables given on the following pages.
For details about the drive control, refer to "Function code F42 (Drive Control Selection 1)."

If you mistakenly assign the terminal command WE-KP, you can no longer edit or modify function code data. To undo this temporarily turn this WE-KP-assigned terminal ON and reassign the WE-KP to a correct command.
WE-KP is only a signal that allows changing function code data, so it does not protect the frequency settings or PID command specified by the and keys.
Even when F00 = 1 or 3, function code data can be changed via the communications link.

4.2 Details of Function Codes
This section provides the details of the function codes. The descriptions are, in principle, arranged in the order of function code groups and in numerical order. However, highly relevant function codes are collectively described where one of them first appears.
4.2.1 Fundamental Functions
F00 specifies whether to protect function code data (except F00) and digital reference data (such as frequency command and PID command) from accidentally getting changed by pressing the / keys on the keypad.
*
Only F00 data can be modified with the keypad, while all other function codes cannot.
To change F00 data, simultaneously press " + " (from 0 to 1) or " + " (from 1 to 0) keys. For similar purposes, WE-KP, a signal that enables editing of function code data from the keypad is provided as a
terminal command for digital input terminals. (Refer to the descriptions of E01 through E07, data = 19) The relationship between the terminal command WE-KP and F00 data are as shown below.
F01 or C30 sets a command source that specifies reference frequency 1 or reference frequency 2.
4-26
When you start accessing the reference frequency or any other parameter with the and keys,
the least significant digit on the display blinks and starts changing. As you are holding down the key, blinking gradually moves to the upper digit places and the upper digits becomes changeable.
Pressing the key moves the changeable digit place (blinking), making it easy to change upper
digits.
Setting function code C30 at "0" (Enable / keys on the keypad) and selecting frequency
command 2 as a frequency command source makes it possible to access the reference frequency in the same manner using the and keys.
If you have set function code F01 at "0" ( / keys on keypad) but have selected a frequency
command source other than frequency 1 (i.e., frequency 2, via communications link, or as a multi-frequency), then using the or key cannot change the frequency command even if the keypad is in Running mode. Pressing either of these keys just displays the currently selected frequency command.
Setting function code F01 at "8" ( / keys on keypad) enables the balanceless-bumpless
switching. When the frequency command source is switched to the keypad from any other source, the inverter inherits the current frequency that has applied before switching, providing smooth switching and shockless running.
When the frequency command source is other than the digital reference setting, the LCD monitor
displays the following.
Keypad takes precedence. The lowest digit blinks.

Operation guide
Keypad is not enabled.
Setting on the analog terminal [12] is
effective. (See the table below.)
Configuring a reference frequency [ 1 ] Using and keys (F01 = 0 (factory default) or 8)
(1) Set function code F01 at "0" or "8" ( / keys on keypad). This cannot be done when the keypad is in
Programming or Alarm mode. To enable frequency setting using the and keys, first place the keypad in Running mode.
(2) Press the or key. The 7-segment LED monitor displays the reference frequency and the LCD monitor
displays the related information including the operation guide, as shown below.
Example of Reference Frequency Configuration Screen
(3) To change the reference frequency, press the or key again. To save the new setting into the
inverter's memory, press the key (when E64 = 1 (factory default)). When the power is turned ON next time, the new setting will be used as an initial reference frequency.
In addition to saving with the key described above, "Automatic saving when the main power is turned
OFF" is also possible (when E64 = 0).

[ 2 ] Using analog input (F01 = 1 to 3, or 5)
When any analog input (voltage input to terminals [12] and [V2], or current input to terminal [C1]) is selected by F01, it is possible to arbitrarily specify the reference frequency by multiplying the gain and adding the bias. The polarity can be selected and the filter time constant and offset can be adjusted.
Adjustable elements of frequency command 1
Offset (C31, C36, C41)
C31, C36 or C41 specifies an offset for analog input voltage or current. The offset also applies to signals from external devices (PLCs, Feedback Sensors, Signal Converters, etc…).
Filter time constant (C33, C38, C43)
C33, C38, or C43 specifies a filter time constant for analog input voltage or current. Choose an appropriate value for the time constant taking into account the response speed of the machinery system since a large time constant slows down the response. When the input voltage fluctuates due to noise, specify a larger time constant.
Polarity (C35, C45)
C35 or C45 specifies the input range for analog input voltage.
4-28
If F01 = 3 (the sum of [12] + [C1] is enabled), the bias and gain are independently applied to each of the voltage and current inputs given to terminals [12] and [C1], and the sum of the two values is applied as the reference frequency.
The analog input less than the bias base point (C50) is limited by the bias value (F18).
Specifying that the data of the bias base point (C50) is equal to or greater than that of each gain base
point (C34, C39 or C44) will be interpreted as invalid, so the inverter will reset the reference frequency to 0 Hz.
Gain and bias
In the case of unipolar input (terminal [12] with C35 = 1, terminal [C1], terminal [V2] with C45 = 1) As shown in the graph above, the relationship between the analog input and the reference frequency specified by
frequency command 1 can arbitrarily be determined by points "A" and "B." Point "A" is defined by the combination of the bias (F18) and its base point (C50); Point "B," by the combination of the gain (C32, C37 or C42) and its base point (C34, C39 or C44).
The combination of C32 and C34 applies to terminal [12], that of C37 and C39, to [C1] (C1 function), and that of C42 and C44, to [C1] (V2 function).
Configure the bias (F18) and gain (C32, C37 or C42), assuming the maximum frequency as 100%, and the bias base point (C50) and gain base point (C34, C39 or C44), assuming the full scale (10 VDC or 20 mA DC) of analog input as 100%.
Example: Setting the bias, gain and their base points when the reference frequency 0 to 60 Hz follows the analog
(Point A) To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is
the bias base point and it is equal to 10% of 10 V (full scale of terminal [12]), set the bias base point to 10% (C50 =
10).
(Point B) To make the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to
100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale of terminal [12]), set the gain base point to 50% (C34 = 50).
input of 1 to 5 VDC to terminal [12] (in frequency command 1).
4-29
Configuring F18 (Bias) and C50 (Bias base point) to specify an arbitrary value (Points A1, A2, and A3) gives the bias as shown above.
A reference frequency can be specified not only with the frequency (Hz) but also with other menu items, depending on the setting of function code E48 (= 3 to 5, or 7).

In the case of bipolar input (terminal [12] with C35 = 0, terminal [V2] with C45 = 0) Setting C35 and C45 data to "0" enables terminal [12] and [V2] to be used for bipolar input (-10 V to +10 V)
respectively. When both F18 (Bias) and C50 (Bias base point) are set to "0," the negative and positive voltage inputs produce
reference frequencies symmetric about the origin point as shown below.
[ 3 ] Using digital input signals UP/DOWN (F01 = 7)
When the UP/DOWN control is selected for frequency setting with a run command ON, turning the terminal command UP or DOWN ON causes the output frequency to increase or decrease, respectively, within the range from 0 Hz to the maximum frequency as listed below.
To enable the UP/DOWN control for frequency setting, it is necessary to set F01 data to "7" and assign the UP and DOWN commands to any of digital input terminals [X1] to [X7], [FWD] and [REV] with any of E01 to E07 (data = 17 or 18).

ON). Speed up by the UP command.
1
Mode holding the final output frequency in the previous UP/DOWN control: The inverter internally holds the last output frequency set by the UP/DOWN control and
applies the held frequency at the next restart (including powering ON).
At the time of restart, if an UP or DOWN terminal command is entered before the internal frequency reaches the output frequency saved in the memory, the inverter saves the current output frequency into the memory and starts the UP/DOWN control with the new frequency. Pressing one of these keys overwrites the frequency held in the inverter.
