This Instruction Manual (Basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (Basic) to the end user.

2. Fire Prevention

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through this Instruction Manual (Basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual (Basic), the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

Incorrect handling may cause hazardous conditions, resulting in death or severe injury.

CAUTION

Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

CAUTION

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed

because these are important to personal safety.

1. Electric Shock Prevention

WARNING

• While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

• Do not run the inverter with the front cover or wiring cover

• Inverter must be installed on a nonflammable wall without

holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

• If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current could cause a fire.

• Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a fire.

3. Injury Prevention

• The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.

• The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.

• Polarity must be correct. Otherwise burst, damage, etc. may occur.

• While power is ON or for some time after power-OFF, do not touch the inverter since the inverter will be extremely hot. Doing so can cause burns.

CAUTION

removed. Otherwise you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.

• Even if power is off, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter circuits and get an electric shock.

• Before wiring, inspection or switching EMC filter ON/OFF connector, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

• This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

• Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.

• The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.

• Setting dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.

• Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.

• Do not replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.

• Do not touch the printed circuit board with wet hands. You may

4. Additional Instructions

Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.

(1) Transportation and installation

CAUTION

• The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.

• Do not stack the boxes containing inverters higher than the number recommended.

• The product must be installed to the position where withstands the weight of the product according to the information in the Instruction Manual.

• Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.

• When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.

• Do not stand or rest heavy objects on the product.

• The inverter mounting orientation must be correct.

• Foreign conductive bodies must be prevented to enter the

inverter. That includes screws and metal fragments or other flammable substance such as oil.

• As the inverter is a precision instrument, do not drop or subject it to impact.

• The inverter must be used under the following environment: Otherwise the inverter may be damaged.

Surrounding air temperature

Ambient humidity 90% RH or less (non-condensing) Storage temperature -20°C to +65°C

Atmosphere

Environment

Altitude, vibration

-10°C to +50°C (non-freezing)

Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Maximum 1000m above sea level for standard operation. 5.9m/s2 or less at 10 to

55Hz (directions of X, Y, Z axes)

or less for the 185K or more.

motor terminal, etc. right after powering off to prevent an electric shock.

A-1

(2) Wiring

• Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. These devices on the inverter output side may be overheated or burn out.

• The connection orientation of the output cables U, V, W to the motor affects the rotation direction of the motor.

(3) Test operation and adjustment

CAUTION

• Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

(4) Operation

• Any person must stay away from the equipment when the retry function is set as it will restart suddenly after trip.

• Since pressing key may not stop output depending on

the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.

• OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter alarm with the start signal ON restarts the motor suddenly.

• The inverter must be used for three-phase induction motors. Connection of any other electrical equipment to the inverter output may damage the equipment.

• Do not modify the equipment.

• Do not perform parts removal which is not instructed in this

manual. Doing so may lead to fault or damage of the inverter.

WARNING

(5) Emergency stop

• A safety backup such as an emergency brake must be provided to prevent hazardous condition to the machine and equipment in case of inverter failure.

• When the breaker on the inverter input side trips, the wiring must be checked for fault (short circuit), and internal parts of the inverter for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.

• When any protective function is activated, appropriate corrective action must be taken, and the inverter must be reset before resuming operation.

(6) Maintenance, inspection and parts replacement

CAUTION

• Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.

(7) Disposing of the inverter

CAUTION

• The inverter must be treated as industrial waste.

General instructions

Many of the diagrams and drawings in this Instruction Manual (basic) show the inverter without a cover or partially open for explanation. Never operate the inverter in this manner. The cover must be always reinstalled and the instruction in this Instruction Manual (basic) must be followed when operating the inverter.

CAUTION

• The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.

• Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise the life of the inverter decreases.

• The effect of electromagnetic interference must be reduced by using a noise filter or by other means. Otherwise nearby electronic equipment may be affected.

• Appropriate measures must be taken to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/ damage the power factor correction capacitor and generator.

• When driving a 400V class motor by the inverter, the motor must be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

• When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations because all parameters return to the initial value.

• The inverter can be easily set for high-speed operation. Before changing its setting, the performances of the motor and machine must be fully examined.

• Stop status cannot be hold by the inverter's brake function. In addition to the inverter's brake function, a holding device must be installed to ensure safety.

• Before running an inverter which had been stored for a long period, inspection and test operation must be performed.

• For prevention of damage due to static electricity, nearby metal must be touched before touching this product to eliminate static electricity from your body.

INSTALLATION AND WIRING

Wiring

(1) Cable sizes etc., of the main control circuit terminals and earth (ground) terminals

Select the recommended cable size to ensure that a voltage drop will be 2% max. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.

and a screw for earthing (grounding).

The line voltage drop can be calculated by the following formula:

line voltage drop [V]=

3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]

1000

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.

CAUTION

· Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely can cause a short circuit or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.

· Use crimping terminals with insulation sleeve to wire the power supply and motor.

INSTALLATION AND WIRING

Wiring

(2) Notes on earthing (grounding)

• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards) A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

• Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the casing, chassis, etc.)

• Use the thickest possible

, 15 and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.

To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to

the instructions on page 155.

(3) Total wiring length

The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.

2) Connect the surge voltage suppression filter (FR-ASF-H) to the 55K or less and the sine wave filter (MT-BSL/BSC)

to the 75K or more on the inverter output side.

CAUTION

· Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the

wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function or a malfunction or fault of the equipment connected on the inverter output side. If fast-response current limit function malfunctions, disable this function. (For Pr.156 Stall prevention operation selection, refer to the chapter 4 of the Instruction Manual (applied).)

· For details of Pr. 72 PWM frequency selection , refer to the chapter 4 of the Instruction Manual (applied). (When using an optional sine

wave filter (MT-BSL/BSC) for the 75K or more, set "25" in Pr.72 (2.5kHz)).

Multi-speed can be selected according to the combination of RH, RM and RL signals.

Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF or STR) to start Jog operation.

Turn on the RT signal to select second function. When the second function such as "second torque boost" and "second V/F (base frequency)" are set, turning on the RT signal selects these functions.

Turn on the MRS signal (20ms or more) to stop the inverter output. Use to shut off the inverter output when stopping the motor by electromagnetic brake.

Used to reset fault output provided when fault occurs. Turn on the RES signal for more than 0.1s, then turn it off. Initial setting is for reset always. By setting Pr.75, reset can be set to enabled only at fault occurrence. Inverter recovers about 1s after the reset is released.

Terminal 4 is valid only when the AU signal is turned on. (The frequency setting signal can be set between 0 and 20mADC.) Turning the AU signal on makes terminal 2 (voltage input) invalid.

AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as PTC input terminal, set the AU/PTC switch to PTC.

When the CS signal is left on, the inverter restarts automatically at power restoration. Note that restart setting is necessary for this operation. In the initial setting, a restart is disabled.

INSTALLATION AND WIRING

Wiring

2.4.6 Changing the control logic

The input signals are set to sink logic (SINK) when shipped from the factory. To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the other position. (The output signals may be used in either the sink or source logic independently of the jumper connector position.)

1)Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be removed.) Pull down the terminal block from behind the control circuit terminals.

2)Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to source logic (SOURCE).

Jumper connector

3)Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it with the mounting screws.

CAUTION

1. Make sure that the control circuit connector is fitted correctly.

2. While power is on, never disconnect the control circuit terminal block.

4) Sink logic and source logic

⋅ In sink logic, a signal switches on when a current flows from the corresponding signal input terminal.

Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.

⋅ In source logic, a signal switches on when a current flows into the corresponding signal input terminal.

Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.

(2) Common terminals of the control circuit (SD 5, SE)

Control circuit terminal

Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not earth(ground) these terminals. Avoid connecting the terminal SD and 5 and the terminal SE and 5. Terminal SD is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) and frequency output signal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler. Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal AM. It should be protected from external noise using a shielded or twisted cable. Terminal SE is a common terminal for the open collector output terminal (RUN, SU, OL, IPF, FU). The contact input circuit is isolated from the internal control circuit by photocoupler.

(3) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled using a transistor instead of a contacted switch as shown on the right.

(4) Wiring instructions

Wiring

1) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm

the cables are run improperly, resulting in an operation panel contact fault.

2) The maximum wiring length should be 30m (200m for terminal FM).

3) Use two or more parallel micro-signal contacts or twin contacts to prevent a contact faults when using contact inputs since the control circuit input signals are micro-currents.

4) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit).

5) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.

6) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.

The inverter's input side MC is used for the above purpose, select class JEM1038-AC3MC for the inverter input side current when making an emergency stop during normal operation.

REMARKS

Since repeated inrush current at power on will shorten the life of the converter circuit (switching life is 100 million times (about 500,000 times for the 200V class 37K or more)), frequent starts/stops must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the inverter.

• Inverter start/stop circuit example

As shown on the left, always use the start signal

To the

(ON or OFF of STF (STR) signal) to make a start

motor

or stop.

*1 When the power supply is 400V class, install a step-

down transformer.

*2 Connect the power supply terminals R1/L11, S1/L21

of the control circuit to the primary side of the MC to hold an alarm signal when the inverter's protective circuit is activated. At this time, remove jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21. (Refer to page 17 for removal of the jumper.)

(2) Handling of the inverter output side magnetic contactor

Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the magnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate. When an MC is provided to switch to a commercial power supply, for example, it is recommended to

use bypass operation Pr. 135 to Pr. 139 (Refer to the chapter 4 of the Instruction Manual (applied)).

Precautions for use of the inverter

2.7 Precautions for use of the inverter

The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items.

(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.

(3) After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

(4) Use cables of the size to make a voltage drop 2% maximum.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. Refer to page 14 for the recommended cable sizes.

(5) The overall wiring length should be 500m maximum.

Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 16.)

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize

interference.

(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.

This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is installed, immediately remove it.

(8) For some short time after the power is switched off, a high voltage remains in the smoothing capacitor. When accessing the

inverter for inspection, wait for at least 10 minutes after the power supply has been switched off, and then make sure that the voltage across the main circuit terminals P/+-N/- of the inverter is not more than 30VDC using a tester, etc.

(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.

· Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules.

· Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.

(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.

Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.

(11) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.

Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short terminals 10E-5.

(Refer to page

(12) Provide electrical and mechanical interlocks for MC1 and

MC2 which are used for bypass operation. When the wiring is incorrect or if there is an electronic bypass circuit as shown on the right, the inverter will be damaged when the power supply is connected to the inverter U, V, W terminals due to arcs generated at the time of switch-over or chattering caused by a sequence error.

Precautions for use of the inverter

(13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the

inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.

(14) Instructions for overload operation

When performing an operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.

(15) Make sure that the specifications and rating match the system requirements.

(16) If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor rotation

speed to be unstable when changing motor speed with analog signal, the following countermeasures are effective.

· Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.

· Run signal cables as far away as possible from power cables (inverter I/O cables).

· Use shield cables as signal cables.

· Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

Failsafe of the system which uses

the inverter

2.8 Failsafe of the system which uses the inverter

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter

fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,

provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the

inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,

without using the inverter, is enabled even if the inverter fails.

(1) Interlock method which uses the inverter status output signals

By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be

detected.

Manual (applied)).

(2) Backup method outside the inverter

Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure

status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter

fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output

even if an inverter fault occurs.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the

backup system such as checking up as below according to the level of importance of the system.

1) Start signal and actual operation check

Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to

the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor

current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the

start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is

recommended to check the three-phase current when using the current detector.

2) Command speed and actual operation check

Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command

and detected speed of the speed detector.

· The output frequency is clamped by the Pr. 2 setting even if the set frequency is lower than the Pr. 2 setting (The frequency will not decrease to the Pr. 2 setting.) Note that Pr. 15 Jog frequency has higher priority than the minimum frequency.

· When the Pr. 1 setting is changed, frequency higher than the Pr. 1 setting can not be set by .

· When performing a high speed operation at 120Hz or more, setting of Pr. 18 High speed maximum frequency is necessary.

(Refer to the chapter 4 of the Instruction Manual (applied).)

ADJUSTMENT

If the Pr. 2 setting is higher than the Pr. 13 Starting frequency value, note that the motor will run at the set frequency according to the acceleration time setting by merely switching the start signal on, without entry of the command frequency.

Remarks

4.5.1 Energy saving operation mode (setting "4")

· When "4" is set in Pr. 60, the inverter operates in the energy saving operation mode.

· In the energy saving operation mode, the inverter automatically controls the output voltage to minimize the inverter output voltage during a constant operation.

REMARKS

· For applications a large load torque is applied to or machines repeat frequent acceleration/deceleration, an energy saving effect is not expected.

4.5.2 Optimum excitation control mode (setting "9")

· When "9" is set in Pr. 60, the inverter operates in the Optimum excitation control mode.

· The Optimum excitation control mode is a control method which controls excitation current to improve the motor efficiency to maximum and determines output voltage as an energy saving method.

REMARKS

· When the motor capacity is too small as compared to the inverter capacity or two or more motors are connected to one inverter, the energy saving effect is not expected.

CAUTION

· When the energy saving mode and Optimum excitation control mode are selected, deceleration time may be longer than

the setting value. Since overvoltage alarm tends to occur as compared to the constant-torque load characteristics, set a longer deceleration time.

· The energy saving mode and Optimum excitation control functions only under V/F control.

When a value other than "9999" is set in Pr. 80 Motor capacity (simple magnetic flux control), the energy saving mode and Optimum excitation control does not function.

(For Simple magnetic flux vector control, refer to the chapter 4 of the Instruction Manual (applied).)

(LONW

communication)

Measured value, set value input

(LONW communication)

If the proportional band is narrow (parameter setting is small), the manipulated variable varies greatly with a slight change of the measured value. Hence, as the proportional band narrows, the response sensitivity (gain) improves but the stability deteriorates, e.g. hunting occurs. Gain K = 1/proportional band

When deviation step is input, time (Ti) is the time required for integral (I) action to provide the same manipulated variable as the proportional (P) action. As the integral time decreases, the set point is reached earlier but hunting occurs more easily.

Set the upper limit value. If the feedback value exceeds the setting, the FUP signal is output. The maximum input (20mA/5V/10V) of the measured value (terminal 4) is equivalent to 100%.

Set the lower limit value. If the measured value falls below the setting range, the FDN signal is output. The maximum input (20mA/5V/10V) of the measured value (terminal 4) is equivalent to 100%.

For deviation lamp input, time (Td) required for providing only the manipulated variable for the proportional (P) action. As the differential time increases, greater response is made to a deviation change.

Y48 signal is output when the absolute value of deviation amount exceeds the deviation limit value.

Select the operation to be performed at the detection of upper, lower, and deviation limit for the measured value input. The operation for PID output suspension function can be selected.

If the output frequency after PID operation remains lower than the Pr. 576 setting for longer than the time set in Pr. 575, the inverter stops operation.

Set the frequency at which the output interruption processing is performed.

Set the level (Pr.577 - 1000%) to release the PID output interruption function.

Set the coefficient on bias side (minimum) of terminal 4 input.

Set the converted % on bias side (minimum) current /voltage of terminal 4 input.

Set the coefficient on gain side (maximum) of the terminal 4 input.

Set the converted % on gain side (maximum) of current/voltage of terminal 4 input.

The parameter number in parentheses is the one for use with the parameter unit (FR-PU04/FR-PU07).

Set the operation interlock time of MC2 and MC3.

Set the time slightly longer (0.3 to 0.5s or so) than the time from when the ON signal enters MC3 until it actually turns on.

Inverter output is stopped (motor coast) at inverter fault.

Operation is automatically switched to bypass operation at inverter fault (Not switched when an external thermal relay operation (E.OHT) or CPU fault (E.CPU) occurs)

Set the frequency to switch inverter operation to bypass operation.

Valid during automatic switchover operation (Pr.139 ≠ 9999) When the frequency command decreases below (Pr.139 - Pr.159) after operation is switched from inverter operation to bypass operation, the inverter automatically switches operation to inverter operation and operates at the frequency of frequency command. When the inverter start command (STF/ STR) is turned off, operation is switched to inverter operation also.

Valid during automatic switchover operation (Pr.139 ≠ 9999) When the inverter start command (STF/ STR) is turned off after operation is switched from inverter operation to bypass operation, operation is switched to inverter operation and the motor decelerates to stop.
