, To connect a dynamic braking resistor, set the overvoltage limit operation parameter H to "1"
(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 H
and H 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.
