Function Description
Ready; Voltage connected to the converter (i.e., main contactor on,
1 ON if available); the drive goes into the switch-on inhibit status. The
DC bus is charged; the drive is inhibited
Shutdown (returns to status not ready to switch on); ramps-down
along the ramp-function generator ramp or along the DC bus
0 OFF1 voltage limit.
At Speed=0 and Current=0, voltage is disconnected; main
contactor off (if available).
Operating
1 All OFF 2 commands are withdrawn.
condition
Voltage disconnected; inhibit the drive output stage. Main
0 OFF2 contactor is de-energized (if available), and the drive goes into the
switch-on inhibit status: Motor coasts down
Operating
1 All OFF 3 commands are withdrawn.
condition
Fast stop: If necessary, remove operating inhibit, fastest possible
0 OFF3 deceleration; at Speed=0 or Current=0, inhibit the drive and go to
switch on inhibit state
1 Operation Enable the drive and accelerate to the specified set point
Inhibit the drive. Drive coasts down (ramp-function generator to
Inhibit
0 zero or tracking), and into the ready status (refer to control word,
operation
bit 0).
Operating
1 ---
condition
Inhibit ramp Ramp function generator output is set to zero. Main contactor
0 function remains in, the drive is not isolated from the supply, drive ramps
generator down along the current limit or at the DC bus voltage limit.

0 function Freeze the current set point from the ramp function generator.
generator
Enable
1 Selected value at the ramp function generator input is switched in.
setpoint
0 Inhibit setpoint Selected value at the ramp function generator input is set to 0.
Group signal is acknowledged at a positive edge; the drive is in the
1 Acknowledge fault status until the fault has been removed and then goes into
switch-on inhibit state.
0 No meaning
Prerequisite: Operation is enabled and Main Setpoint=0. The drive
1 INCH1 ON accelerates as fast as possible to inching setpoint in the forward
direction.
The drive brakes as fast as possible, if INCH1 was previously ON,
0 INCH1 OFF and with Speed=0 and Current=0 goes into the status operation
enabled.
