Set Ramp-Down Time
Enters the time with which, for example, the motor should
brake from the maximum frequency P1082 down to
standstill. If the ramp-down time is set too low, then this
may result in alarms A0501 (current limit active), A0502
(overvoltage limit active) or the drive tripping with fault
F0001 (overcurrent) or F0002 (overvoltage).

Set OFF 3 Ramp-Down Time
Enters the time with which, for example, the motor should
brake from the maximum frequency P1082 down to
standstill with an OFF3 Command (Fast Stop). If the ramp-
down time is set too low, then this may result in alarms
A0501 (current limit active), A0502 (overvoltage limit active)
or the drive tripping with fault F0001 (overcurrent) or F0002
(overvoltage).

WARNING
The motor data identification routine must not be used for loads which are
potentially hazardous (e.g. suspended loads for crane applications). Before
the motor data identification run is started, the potentially hazardous load must
be carefully secured (e.g. by lowering the load to the floor or by clamping the
load using a motor holding brake).
