AC70 VC CONTROL FREQUENCY INVERTER MANUAL
PERIPHERAL EQUIPMENTS AND OPTIONS
65
Input side noise filter
Reduce frequency inverter disturbance to the power and
reduce the power grid disturbance.
Braking resistor
Passive energy consume unit of electric braking.
Consumption braking unit
Electric braking control unit, controlling the braking
resistance consume the regenerated electric power of the
motor efficiently.
Output side noise filter
Reduce the output side wire electromagnetic disturbance.
Standby system
Standby system for inverter malfunction.
Heat relay
Protect the motor while over load.
0-phase reactor
Reduce electromagnetic disturbance of the frequency
inverter (suitable for input/output side).
Main loop surge absorbable unit
Restrain surge voltage while main loop switch components
act.
Winding surge absorbable unit
Restrain surge voltage when the AC contactor acts.
