The command is only executed in the READY TO POWER-ON condition. After the
command has been accepted, the system changes-over into the PRECHARGING
status.
The pre-charging is executed, the system changes into the READY status, and
then into the RUN status. If the signal changes from H to L, this signifies an OFF1
command. The system goes into the OFF1 status after the command has been ac-
cepted. The setpoint is inhibited at the ramp-function generator input (setpoint = 0),
so that the drive ramps-down along the down ramp (P464). The inverter pulses are
inhibited and the circuit-breaker is opened after the OFF (OPEN) shutdown
frequency has been reached. Change into the READY TO POWER-UP status.

After the command has been accepted, the inverter pulses are inhibited and the
circuit-breaker is opened. The system changes into the POWER-ON INHIBIT
status.

After the command has been accepted, the setpoint at the ramp-function generator
input is inhibited (setpoint = 0), so that the drive decelerates along the
parameterized fast stop ramp for OFF3 (P353) to the OFF shutdown frequency
(P405 = threshold value, P406 = hysteresis). The pulses are then inhibited and the
circuit-breaker opened. The system changes over into the POWER-ON INHIBIT
status.

After the inverter enable command (H signal) has been accepted, if the READY
status is available and the de-energization time (P704) has expired since the last
shutdown, the system changes into the OPERATION status, the inverter pulses
are enabled and the setpoint is approached along the ramp-function generator
ramp. The INVERTER INHIBIT command (inverter inhibit) is executed with an L
signal.
After the command has been accepted, the system changes into the READY
status, the inverter pulses are inhibited. If the OFF1 status is available, the inverter
pulses are inhibited and the circuit-breaker opened.

After the ramp-function generator (RFG) enable command has been accepted, the
ramp-function generator is enabled, and it approaches the setpoint.

After the RFG hold command has been accepted, the actual setpoint at the ramp-
function generator output, is held (frozen).

After the setpoint enable command has been accepted, if the energization time
(P704) has expired, the setpoint at the ramp-function generator input, is enabled.

The command is only executed in the FAULT status. After the command has been
accepted, all of the actual faults are deleted. The individual fault messages can be
viewed, with date and time, in the OP2 message memory. The messages are
retained until they have been specifically deleted using the OP2. If there are no
faults, the system changes into the POWER-ON INHIBIT or READY TO POWER-
UP status. If faults are present, the drive converter remains in the FAULT status.
