Notes:
1) Braking wires are connected as simultaneous braking method from factory shipment. For inverter driving, please open terminal box to change
braking connection circuit to those are shown above. And be sure to disconnect lead wire (marked with ※ )
2) For separated braking method or direct current (quick) braking method, remove the connection bar as shown above.
3) Terminal block has 2 lines of terminals (upper and lower line). Be sure to connect power supply wires to upper line terminals. If connect to the
lower line, brake will not be released.
4) For inverter driving, connect braking wires directly from power source. do not connect through inverter.
5) When use inverter drive, at low frequency, the noise may be slightly louder. This noise is not malfunction and does not affect to performance.
6) For inverter driving, the power factor improving capacitor cannot be connected to the motor circuit.
Brake usage precautions
1. Connect only brake power without power the motor may deteriorate the motor.
2. If power-factor improving capacitor is attached, be sure to use separated braking method. For inverter driving, the power factor improving
capacitor cannot be connected to the motor circuit.
3. To drive the motor with an inverter or to control the input power, please connect the brake to the power source side of the inverter. (Connecting
to the output side of the inverter may deteriorate the power source equipment)
4. In the inverter-driving mode, the noise may be slightly louder in the low-frequency zone. However, this type of noise will not deteriorate any
motor functions.
5. To operate motor at frequency of 25Hz or less, observe the rate time of 1 hour or 25% ED.
6. To use inverter-driving for 400V class motor, surge voltage from wiring fixed number may occur between the terminal,and this voltage may
deteriorate the insulation of motor. Please use the method below for solution.
(1) Insulation strengthening method
Please use 400V class inverter-driving insulation strengthening geared motor.
In Mitsubishi geared motor, insulation strengthening motor are shown below.
- Standard geared motor ---0.1～2.2kW
(2) Inverter side surge voltage controlling method
At the secondary side of inverter, please connect the filter for control surge voltage of the motor which decrease within 850V. For Mitsubishi
inverter-driving, please connect optional surge voltage controlling filter (FR-ASF-H) at the secondary side of inverter.
