,
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 deceleration
stopping 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
f308
and
f309
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 the power off.
