Connection with Peripheral Devices

Peripheral devices necessary for driving the FR-F700 series inverter are indicated below.

Three-phase AC power supply

Use within the permissible power supply specifications of the inverter.

(Refer to page 7.)

Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse

The breaker must be selected carefully since an in-rush current flows in the inverter at power on.

(Refer to page 57.)

Magnetic contactor(MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorten.

(Refer to page 57.).

Reactor (FR-HAL, FR-HEL)

Reactors (option) should be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (1000kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. For the 55K or less, remove the jumpers across terminals P/+-P1 to connect to the DC reactor.

(Refer to page 51.).

PLC

RS-485 terminal block

The inverter can be connected with computers such as PLC. It supports Mitsubishi inverter protocol and Modbus-RTU (binary) protocol.

Inverter (FR-F700)

The life of the inverter is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. (Refer to page 8.) This must be noted especially when the inverter is installed in an enclosure. Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit to protect them from noise.

Why Can the Inverter Save Energy?

The load torque of a motor-driven machine generally changes depending on speed. On the other hand, motor output is proportional to the product of load torque and speed as indicated in the following formula, and therefore, necessary motor output varies with speed.

Motor output P = T

× N/(9550 × η) [kW]

T : Motor shaft-equivalent load torque [N·m] N : Motor speed [r/min] η : Machine efficiency

When this motor is operated by the inverter, the inverter output provides the frequency f appropriate to the motor speed, and the then output voltage V is determined by a "V/f = constant" pattern in the case of a constant-torque load. For example, when the motor is operated at middle speed, f, i.e. output voltage V, decreases, and therefore, the inverter output power V × I reduces if the output current I is constant. Proportionately, the inverter input current decreases and the power consumption reduces. Namely, when the motor output reduces, the input power of the inverter also decreases as a matter of course. The fundamental principle of energy saving by the inverter is to eliminate wasted power consumption by minimizing loss caused by the other devices and minimizing the motor output as compared to the other system (for example, commercial power supply operation or secondary resistance control of wound-rotor motor). A maximum energy saving effect is produced on a fan, pump or like by the variable-torque load characteristic that reduces load torque as speed decreases.

Motor speed control enables substantial energy-saving operation as compared to commercial power supply operation.

*1. The applied motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor. *2. The rated output capacity indicated assumes that the output voltage is 220V for 200V class and 440V for 400V class. *3. When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically decreases if the inverter output

current exceeds the value in parenthesis of the rated current. This may cause the motor noise to increase.

*4. The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty,

allow time for the inverter and motor to return to or below the temperatures under 100% load.

*5. The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.

However, the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply. *6. The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables). *7. When the hook of the inverter front cover is cut off for installation of the plug-in option, the inverter changes to an open type (IP00). *8. FR-DU07 : IP40 (Except for the PU connector).

Connected to the AC power supply terminals R/L1 and S/L2. To retain the alarm display and alarm output, apply external power to this terminal. Connect the brake unit (FR-BU, BU, MT-BU5), power regeneration common converter (FRCV), power regeneration converter (MT-RC) or high power factor converter (FR-HC, MT-HC). For the 55K or less, remove the jumper across terminals P/+ - P1 and connect the DC reactor. (For the 75K or more, a DC reactor is supplied as standard.)

Turn on the STF signal to start forward rotation and turn it off to stop. Turn on the STR signal to start reverse rotation and turn it off to stop.

Turn on the STOP signal to self-hold the start signal.

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 acceleration/deceleration time. 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 alarm output provided when protective function is activated. Turn on the RES signal for more than 0.1s, then turn it off. Recover about 1s after reset is cancelled. Terminal 4 is made valid only when the AU signal is turned on. (The frequency setting signal can be set between 4 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.

Common terminal for contact input terminal (sink logic) and terminal FM. Common output terminal for 24VDC 0.1A power supply (PC terminal). Isolated from terminals 5 and SE. When connecting the transistor output (open collector output), such as a programmable controller (PLC), when sink logic is selected, connect the external power supply common for transistor output to this terminal to prevent a malfunction caused by undesirable currents. Can be used as 24VDC 0.1A power supply. When source logic has been selected, this terminal serves as a contact input common.

When connecting the frequency setting potentiometer at an initial status, connect it to terminal 10. Change the input specifications when connecting it to terminal 10E.

Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the maximum output frequency at 5V (10V, 20mA) and makes input and output proportional. Use Pr.73 to switch from among input 0 to 5VDC (initial setting), 0 to 10VDC, and 4 to 20mA. Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the maximum output frequency at 20mA (5V, 10V) makes input and output proportional. This input signal is valid only when the AU signal is on (terminal 2 input is invalid). Use Pr.267 to switch between the input 4 to 20mA and 0 to 5VDC, 0 to 10VDC (initial setting). Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal 2 or 4 frequency setting signal. Use Pr.73 to switch between the input 0 to ±5VDC and 0 to ±10VDC (initial setting). Input resistance 10kΩ ± 1kΩ, Maximum permissible voltage ± 20VDC Common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal AM. Do not earth (ground).

When the STF and STR signals are turned on simultaneously, the stop command is given.

 Set in Pr. 22 the ratio of the output current to the rated inverter

current at which stall prevention operation will be performed. Normally set this parameter to120% (initial value).

 When “9999” is set in Pr. 22, stall prevention operation level can be

changed by the signal to the auxiliary input terminal (terminal 1). For the adjustment of bias/gain of analog signal, use Pr. 148 and Pr. 149.

 During high-speed operation above the rated motor frequency,

acceleration may not be made because the motor current does not increase. If operation is performed in a high frequency range, the current at motor lockup becomes smaller than the rated output current of the inverter, and the protective function (OL) is not executed if the motor is at a stop. To improve the operating characteristics of the motor in this case, the stall prevention level can be reduced in the high frequency region. This function is effective for performing operation up to the high speed region on a centrifugal separator etc. Normally, set 60Hz in Pr. 66 and 100% in Pr. 23.

 By setting "9999" (initial value) in Pr. 23 Stall prevention operation

level compensation factor at double speed, the stall prevention operation level is constant at the Pr. 22 setting up to 400Hz.

Adjustment of terminal FM and AM (calibration)

The operation panel and parameter unit can be used to calibrate the full scales of the terminals FM and AM.

(1) FM terminal calibration (C0(Pr.900))

⋅ The terminal FM is preset to output pulses. By setting the

Calibraton parameter C0 (Pr. 900), the meter connected to the inverter can be calibrated by parameter setting without use of a calibration resistor.

⋅ Using the pulse train output of the terminal FM, a digital

display can be provided by a digital counter. The monitor value is 1440 pulses/s output at the full-scale value of Pr. 54 FM terminal function selection.

Indicator 1mA full-scale analog meter

*1 Not needed when the operation panel (FR-DU07) or parameter unit (FR-

PU04) is used for calibration. Used when calibration must be made near the frequency meter for such a reason as a remote frequency meter. However, the frequency meter needle may not deflect to full-scale if the calibration resistor is connected. In this case, use this resistor and operation panel or parameter unit together.

(2) AM terminal calibration (C1(Pr.901))

⋅ The AM terminal is factory-set to output 10VDC in the full-

scale state of each monitor item. By setting the calibration parameter C1 (Pr. 901), the ratio (gain) of the output voltage can be adjusted to the meter scale. Note that the maximum output voltage is 10VDC.

(Note) 1. Connect so that the terminal symbols are the same for both inverter and brake unit. Incorrect connection will damage the inverter.

2. Minimize the cable length between the inverter and brake unit and between the discharging resistor and brake unit. Use a twisted cable whe n the wiring length exceeds 2m. (If twisted cables are used, the wiring length should be within 5m.)

 Handling precautions

1. The thermal relay in the brake unit will trip if the rated torque is continuously output. After a trip, reset the inverter and increase its deceleration time seting.

2. The maximum temperature rise of the discharging resistor is 100 °C. Use heat-resistant wires and wire to avoid contact with resistors.

 Application of the sine wave filter

For the FR-F700 series (75K or more) inverter, the motor voltage and current can be made to nearly sine wave shaped by providing a sine wave filter on the output side.

1) Low noise

2) Surgeless

3) Motor loss reduction (use of standard motor)

 Application condition

The following conditions have to be satisfied to install the sine wave filter.

1) Change the Pr. 72 setting to "25". (The initial value is "2".)

The carrier frequency changes to 2.5KHz. (The sine wave filter is designed on condition that the carrier frequency is 2.5KHz. Be sure to change the setting properly.) If the inverter is operated with Pr.72 set to other than "25", the inverter and sine wave filter may be damaged.

2) The sine wave filter can be used only for 60 Hz or less inverter frequency.

Note that the filter can not be used for the higher frequency operation than this. (Otherwise the filter loss will increase. )

3) Use the inverter with capacity one rank higher. *2

4) Install an external thermal relay of the motor.

Precautions for Operation/Selection

Precautions for use of the inverter Precautions for selection

Safety Precautions

 To operate the inverter correctly and safely, be sure to

read the "instruction manual" before starting operation.

 This product has not been designed or manufactured

for use with any equipment or system operated under life-threatening conditions.

 Please contact our sales office when you are

considering using this product in special applications such as passenger mobile, medical, aerospace, nuclear, power or undersea relay equipment or system.

 Although this product is manufactured under strict

quality control, safety devices should be installed when a serious accident or loss is expected by a failure of this product.

 The load used should be a three-phase induction motor only.

Operation

 A magnetic contactor (MC) provided on the primary

side should not be used to make frequent starts and stops. It could cause the inverter to fail.

 However, at this time, the motor cannot be brought to a

sudden stop. Hence, provide a mechanical stopping/ holding mechanism for the machine/equipment which requires an emergency stop.

 It will take time for the capacitor to discharge after

shutoff of the inverter power supply. When accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched off, and check to make sure that there are no residual voltage using a tester or the like.

Wiring

 Application of power to the output terminals (U, V, W) of

the inverter will damage the inverter. Therefore, fully check the wiring and sequence to ensure that wiring is correct, etc. before powering on.

 The terminals P/+, P1, N/- are provided for connection of a

dedicated option. Connect only a dedicated option. Do not short the frequency setting power supply terminal 10 and common terminal 5 or the terminal PC and terminal SD.

 Do not wire the maker-dedicated terminal PR/PX.

Installation

 Avoid hostile environment where oil mist, fluff, dust particles,

etc. are suspended in the air, and install the inverter in a clean place or put it in an ingress-protected "enclosed" panel. When placing the inverter in a panel, determine the cooling system and panel dimensions so that the ambient temperature of the inverter is within the permissble value. (refer to page 8 for the specified value)

 Do not install the inverter on wood or other combustible

material as it will be hot locally.

 Install the inverter in the vertical orientation.

Setting

 The inverter can be operated as fast as a maximum of

400Hz by parameter setting. Therefore, incorrect setting can cause a danger. Set the upper limit using the maximum frequency limit setting function.

 A setting higher than the initial value of DC injection

brake operation voltage or operation time can cause motor overheat (electronic thermal relay trip).

Inverter capacity selection

 When operating a special motor or more than one motor in

parallel with a single inverter, select the inverter capacity so that 1.1 times the total rated motor current is less than the rated output current of the inverter.

Starting torque of the motor

 The start and acceleration characteristics of the motor

driven by the inverter are restricted by the overload current rating of that inverter. Generally the torque characteristic is less than when the motor is started by a commercial power supply. When torque boost adjustment or simple magnetic flux vector cannot provide enough starting torque, select the inverter of one rank higher capacity or increase the capacities of both the motor and inverter.

Acceleration and deceleration times

 The acceleration/deceleration time of the motor depends

on the motor-generated torque, load torque and moment of inertia of the load (GD

 When the current limit function or stall prevention function is

activated during acceleration/deceleration, increase the acceleration/deceleration time as the actual time may become longer.

 To decrease the acceleration/deceleration time,

increase the torque boost value (setting of a too large value may activate the stall prevention function at a start, longer the acceleration time), use the simple magnetic flux vector control, or increase the inverter and motor capacities. To decrease the deceleration time, it is necessary to add the brake unit (FR-BU, MTBU5), power regeneration common converter (FR-CV), power regeneration unit (MT-RC) or a similar device to absorb braking energy.

Power transfer mechanism

(gear, belt, chain, etc.)

 When an oil-lubricated gear box, speed change gear or

similar device is used in the power transfer system, note that continuous operation at low decelerated speed only may deteriorate oil lubrication, causing seizure. When performing fast operation at higher than 60Hz, fully note that such operation will cause strength shortage due to the noise, life or centrifugal force of the power transfer mechanism.

Instructions for overload operation

 When performing operation of frequent start/stop of the

inverter, rise/fall in the temperature of the transistor element of the inverter will 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.

Precautions for Peripheral Device Selection

Installation and selection of moulded case circuit breaker

Install a moulded case circuit breaker (MCCB) on the power receiving side to protect the wiring of the inverter primary side. For MCCB selection, refer to page 57 since it depends on the inverter power supply side power factor (which changes depending on the power supply voltage, output frequency and load). Note that the operation characteristics of the completely electromagnetic MCCB changes according to the higher harmonic current, so a larger capacity must be selected. (Check it in the data of the corresponding breaker.) As an earth (ground) leakage breaker, use the Mitsubishi earth (ground) leakage breaker designed for harmonics and surges. (Refer to page 58.) When installing a moulded case circuit breaker on the secondary side of the inverter, contact each manufacturer for selection of the moulded case circuit breaker.

Handling of primary side magnetic contactor

For operation via external terminal (terminal STF or STR used), provide a primary side MC to prevent an accident caused by a natural restart at power recovery after a power failure, such as an instantaneous power failure, and to ensure safety for maintenance work. Do not use this magnetic contactor to make frequent starts and stops. (The switching life of the inverter input circuit is about 1,000,000 times.) For parameter unit operation, an automatic restart after power failure is not made and the MC cannot be used to make a start. Note that the primary side MC can stop the operation, but the regenerative brake specific to the inverter does not operate and the motor coasts to stop.

Handling of secondary 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 commercial power supply-inverter switchover operation Pr. 135 to 139.

Thermal relay installation

The inverter has an electronic thermal relay function to protect the motor from overheating. However, when running multiple motors with one inverter or operating a multi-pole motor, provide a thermal relay (OCR) between the inverter and motor. In this case, set the electronic thermal relay function of the inverter to 0A. And for the setting of the thermal relay, add the line-to-line leakage current (refer to page 61) to the current value on the motor rating plate. For low-speed operation where the cooling capability of the motor reduces, it is recommended to use a thermal protector or thermistor-incorporated motor.

Secondary side measuring instrument

When the wiring length between the inverter and motor is long, select the device that has enough current rating. Otherwise the measuring instrument or CT which is used especially for the 400V class small-capacity inverter may generate heat due to the influence of line leakage current. To measure and display the output voltage and output current of the inverter, it is recommended to use the terminal AM-5 output function of the inverter.

Disuse of power factor improving capacitor (power capacitor)

The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent protection, do not install a capacitor or surge suppressor. For power factor improvement, use the power factor improving DC reactor (see page 51).

Wire thickness and wiring distance

When the wiring length between the inverter and motor is long, use thick wires so that the voltage drop of the main circuit cable is 2% or less especially at low frequency output. (A selection example for the wiring distance of 20m is shown on page 57) Especially at a long wiring distance, the maximum wiring length should be within 500m since the overcurrent protection function may be misactivated by the influence of a charging current due to the stray capacitances of the wiring. (The overall wiring length for connection of multiple motors should be within the value in the table below.)

Use the recommended connection cable when installing the operation panel away from the inverter unit or when connecting the parameter unit. For remote operation via analog signal, wire the control cable between the operation box or operation signal and inverter within 30m and away from the power circuits (main circuit and relay sequence circuit) to prevent induction from other devices. When using the external potentiometer instead of the parameter unit to set the frequency, use a shielded or twisted cable, and do not earth (ground) the shield, but connect it to terminal 5 as shown below.

Earth (Ground)

When the inverter is run in the low acoustic noise mode, more leakage currents occur than in the non-low acoustic noise mode due to high-speed switching operation. Be sure to use the inverter and motor after grounding (earthing) them. In addition, always use the earth (ground) terminal of the inverter to earth (ground) the inverter.

Noise

When performing low-noise operation at higher carrier frequency, electromagnetic noise tends to increase. Therefore, refer to the following measure example and consider taking the measures. Depending on the installation condition, the inverter may be affected by noise in a non-low noise (initial) status.  The noise level can be reduced by decreasing the

carrier frequency (Pr. 72).

 As measures against AM radio broadcasting noise and

sensor malfunction, turning on the built-in noise reduction filter produces an effect. (For the switching method, refer to the instruction manual.)

 As measures against induction noise from the power

cable of the inverter, an effect is produced by putting a distance of 30cm (at least 10cm) or more and using a twisted pair shielded cable as a signal cable. Do not earth (ground) shield but connect it to signal common cable.

 Harmonic suppression guideline Harmonic currents flow from the inverter to a power receiving point via a power transformer.The harmonic suppression guidelines were established to protect other consumers from these outgoing harmonic currents. The three-phase 200V input specifications 3.7kW or less are previously covered by "Harmonic suppression guideline for household appliances and general-purpose products" and other models are covered by "Harmonic suppression guideline for consumers who receive high voltage or special high voltage". However, the generalpurpose inverter has been excluded from the target products covered by "Harmonic suppression guideline for household appliances and general-purpose products" in January 2004 and all capacities of all models are now target products of "Harmonic suppression guideline for consumers who receive high voltage or special high voltage". ⋅ Harmonic suppression guideline for consumers who

receive high voltage or special high voltage

This guideline sets forth the maximum values of harmonic currents outgoing from a high-voltage or especially high-voltage consumer who will install, add or renew harmonic generating equipment. If any of the maximum values is exceeded, this guideline requires that consumer to take certain suppression

measures. Users who use models other than the target models are not covered by the guideline. However, we ask to connect an AC reactor and a DC reactor as before.

Application to Motor

Application to standard motor

When the Mitsubishi standard squirrel-cage motor (SFJR, 4-pole) and inverter of the same capacity are used, the torque characteristics are as shown below.

*1 The 60Hz torque reference indicates that the rated torque of the motor running at

60Hz is 100%, and the 50Hz torque reference indicates that the rated torque of the

motor running at 50Hz is 100% *2 Torque boost minimum (0%) *3 Torque boost standard (initial value) *4 Torque boost large (0.75 K... 10%, 1.5K to 3.7 K... 7%, 5.5K, 7.5K... 6%, 11K or more... 4%) *5 Enabled for torque boost adjustment (3.7kW or less) or simple magnetic flux vector

control (slip compensation setting) *6 A general-purpose, squirrel-cage motor must be used at lower continuous operating

torque in rated operation as shown in the chart since the cooling capability of the fan

installed on the rotor reduces at a lower speed. (Instantaneous torque occurs) *7 200/220V 60Hz or 200V 50Hz in the chart indicates a motor torque standard (base

frequency set in Pr. 3 of the inverter) and is not the frequency of the power supply.

You can also set 60Hz in a 50Hz power supply area. *8 As shown in the chart, the 60Hz torque reference setting allows you to use the motor

more efficiently as it can bring out the 100% torque of the motor continuously. *9 This chart shows the characteristic available when a constant-torque load is selected

for load pattern selection (Pr. 14).

Continuous operation torque (*6 to 8)

Output frequency (Hz)

Motor loss and temperature rise

The motor operated by the inverter has a limit on the continuous operating torque since it is slightly higher in temperature rise than the one operated by a commercial power supply. At a low speed, reduce the output torque of the motor since the cooling effect decreases. When 100% torque is needed continuously at low speed, consider using a constant-torque motor.

Torque characteristic

The motor operated by the inverter may be less in motor torque (especially starting torque) than the one driven by the commercial power supply. It is necessary to fully check the load torque characteristic of the machine.

Vibration

The machine-installed motor operated by the inverter may be slightly greater in vibration than the one driven by the commercial power supply. The possible causes of vibration are as follows.

1.Vibration due to imbalance of the rotator itself including the machine

2.Resonance due to the natural oscillation of the mechanical system. Caution is required especially when the machine used at constant speed is operated at variable speed. The frequency jump function allows

resonance points to be avoided during operation. (During acceleration/deceleration, the frequency within the setting range is passed through.) An effect is also produced if the PWM carrier frequency in Pr. 72 is changed. When a two-pole motor is operated at higher than 60Hz, caution should be taken since such operation may cause abnormal vibration.

Inverter-driven 400V class motor

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. In such a case, consider taking the following measures. (1) Rectifying the motor insulation

1. Use a "400V class inverter driven insulationenhanced motor". Note: The four poles of the Mitsubishi standard

motor (SF-JR, SB-JR) have the 400V class inverter driving insulation-enhanced feature.

2. For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverterdriven, dedicated motor".

(2) Suppressing the surge voltage on the inverter side

Connect a filter on the secondary side of the inverter to suppress a surge voltage so that the terminal voltage of the motor is 850V or less. When driving by the Mitsubishi inverter, connect an optional surge voltage suppression filter (FR-ASF-H) for the 55K or less and an optional sine wave filter (MT-BSL, BSC) for the 75K or more on the inverter output side.

Application to constant-torque motor

Since a constant-torque motor is greater in current than the standard motor, the inverter capacity may be one rank higher. For a constant-torque motor, decrease the torque boost setting. Recommended value 0.75kW... 6%, 1.5 to 3.7kW... 4%,

5.5 to 7.5kW...3%, 11 to 37kW...2%,

45 to 55kW...1.5%, 75k or more...1% When two or more motors are operated synchronously, torque imbalance is likely to occur as motor slip is smaller than that of the standard motor.

Application to special motors

Pole changing motor

As this motor differs in rated current from the standard motor, confirm the maximum current of the motor and select the inverter. Be sure to change the number of poles after the motor has stopped. If the number of poles is changed during rotation, the regenerative overvoltage protecion circuit may be activated to cause an inverter alarm, coasting the motor to a stop.

Geared motor

The continuous operating rotation range of this motor changes depending on the lubrication system and maker. Especially in the case of oil lubrication, continuous operation in the low speed range only can cause gear seizure. For fast operation at higher than 60Hz, please consult the maker.

Synchronous motor

This motor is not suitable for applications of large load variation or impact, where out-of-sync is likely to occur. Please contact us when using this motor because its starting current and rated current are greater than those of the standard motor and will not rotate stably at low speed.
