Enter the ramp-down time, i.e. the
deceleration time from the
synchronous motor speed n
s
to 0
RPM. Choose a ramp-down time such
that no over-voltage arises in the
inverter due to regenerative
operation of the motor, and such
that the generated current does not
exceed the current limit set in
4-18 Current Limit. The value 0.00
corresponds to 0.01 s in speed mode.
