Speed actual value at the OFF1/OFF3 instant
If an event initiates OFF1 or OFF3 - and the "Extended setpoint channel" function module is
not active - then the drive ramps down via the OFF1 and OFF3 times parameterized in the
"Ramp down" dialog.
1. Enter a value in p1121[0] for the ramp-down time.
2. Enter a value in p1135 for the OFF3 ramp-down time.
3. To activate the interpolator for the down ramp, in the drop-down list for p1189[0], select
"Yes". The parameters for the down ramp are only displayed if the extended setpoint
channel is deactivated.
