Function Description
1 No Ramp Stop Ramp Stop command is withdrawn.
The motor decelerates under ramp control using deceleration rate1
0 Ramp Stop (Pr 2.21); inhibits the drive and go to 'Ready For Switching On'
state.
1 No Coast Stop Coast Stop command is withdrawn.
Voltage disconnected; inhibit the drive output stage. Main
0 Coast Stop contactor is de-energized (if available), and the drive goes into the
'Switching On Inhibited' status: Motor coasts down
1 No Quick Stop Quick Stop command is withdrawn.
The motor decelerates under ramp control using deceleration rate2
0 Quick Stop
(Pr 2.22); inhibits the drive and go to 'Switching On Inhibited' state.
Enable
1 Enable the drive and accelerate to the specified set point.
Operation
Disable Inhibit the drive. Drive coasts down (ramp-function generator to
0
Operation zero or tracking), and into the Switched On' status.
1 Enable RFG Enables the ramp function generator output.
Ramp function generator output is set to zero. Main contactor
0 Reset RFG remains in, the drive is not isolated from the supply, drive ramps
down along the current limit or at the DC bus voltage limit.
1 Unfreeze RFG Unfreezes the ramp function generator output.
0 Freeze RFG Freezes the current set point from the ramp function generator.
Enable
1 Selected value at the ramp function generator input is switched in.
Setpoint
Inhibit
0 Selected value at the ramp function generator input is set to 0.
Setpoint
Group signal is acknowledged at a positive edge; the drive is in the
Fault
1 'fault' status until the fault has been removed and then goes into
Acknowledge
'switch-on inhibit' state.

Prerequisite: Operation is enabled and Main Setpoint=0. The drive
1 JOG1 ON accelerates as fast as possible to jogging setpoint (Pr 1.05) in the
forward direction.
The drive brakes as fast as possible along the RFG, if 'JOG1' was
0 JOG1 OFF
previously ON, and goes into 'operation enabled' at standstill.
Prerequisite: Operation is enabled and Main Setpoint=0. The drive
1 JOG2 ON accelerates as fast as possible to jogging setpoint (Pr 1.05) in the
reverse direction.
The drive brakes as fast as possible along the RFG, if 'JOG2' was
0 JOG2 OFF
previously ON, and goes into 'operation enabled' at standstill.
