2) Optional dynamic braking resistors
6
Optional dynamic braking resistors are listed below. All these resistors are 3%ED in operation rate
Note 1: The data in Rating above refer to the resultant resistance capacities (watts) and resultant resistance
Note 2: Braking resistors for frequent regenerative braking are optionally available. For more information,
Title Function
Dynamic braking selection
Overvoltage limit operation
Braking resistor operation rate
Dynamic braking resistor capacity
To connect a dynamic braking resistor, set the overvoltage limit operation parameter
(Disabled).
To use this inverter in applications that create a continuously regenerative status (such as downward
movement of a lift, a press or a tension control machine), or in applications that require slowdown stop-
ping of a machine with a significant load inertial moment, increase the dynamic braking resistor capacity
according to the operation rate required.
To connect an external dynamic braking resistor, select one with a resultant resistance value greater
than the minimum allowable resistance value. Be sure to set the appropriate operation rate in
and to ensure overload protection.
When using a braking resistor with no thermal fuse, connect and use a thermal relay as a control circuit
for cutting power off.
