21.01 Unused
21.02 Off1Mode (off 1 mode)
Conditions for motor deceleration when
UsedMCW (7.04) bit 0 On (respectively Off1N) is set to low:
0 =
RampStop The input of the drives ramp is set to zero. Thus, the drive stops according to DecTime1
(22.02). When reaching M1ZeroSpeedLim (20.03) the firing pulses are set to 150
degrees to decrease the armature current. When the armature current is zero the firing
pulses are blocked, the contactors are opened, field exciter and fans are stopped,
default.
1 =
TorqueLimit The output of the drives ramp is set to zero. Thus, the drive stops at the active torque
limit. When reaching M1ZeroSpeedLim (20.03) the firing pulses are set to 150 degrees
to decrease the armature current. When the armature current is zero the firing pulses are
blocked, the contactors are opened, field exciter and fans are stopped.
2 =
CoastStop The firing pulses are immediately set to 150 degrees to decrease the armature current.
When the armature current is zero the firing pulses are blocked, the contactors are
opened, field exciter and fans are stopped.
3 =
DynBraking dynamic braking
Note:
In case
UsedMCW (7.04) bit 0 On and UsedMCW (7.04) bit 3 Run are set to low (run and on commands are
taken away) at the same time or nearly contemporary
Off1Mode (21.02) and StopMode (21.03) must
have the
same setting.

21.04 E StopMode (emergency stop mode)
Conditions for motor deceleration when
UsedMCW (7.04) bit 2 Off3N (respectively E-stop) is set low:
0 =
RampStop The input of the drives ramp is set to zero. Thus, the drive stops according to E
StopRamp (22.04). When reaching M1ZeroSpeedLim (20.03) the firing pulses are set to
150 degrees to decrease the armature current. When the armature current is zero the
firing pulses are blocked, the contactors are opened, field exciter and fans are stopped.
