1. If the “Allow Braking” box in the System Configuration is checked, the system will be able to apply
regeneration torque to slow down the motor. Otherwise, the limit will be 0%.
When more than one limiting factor is present, the lowest limitation dominates. The most serious motoring
limitation is Over Speed. If configured to do so, this limitation can actually cause motor regeneration in order to
slow down the speed. The most serious regeneration limitation is Over Safety Voltage. This limitation can
actually change the motor’s control mode while the condition exists because the inverter will be destroyed if the
voltage remains above the allowable value. This control mode, called Forced Voltage Control, takes priority over
any other limit.
