the output current does not exceed the
current limit in
4-18 Current Limit during
ramping. The value 0.00 corresponds to 0.01
s in speed mode. See ramp-down time in

deceleration time from the synchronous
motor speed n

to 0 RPM. Select a ramp-
down time such that no overvoltage 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
