The following section lists the status messages of the main operating
states of the drive, the drive passes through, when it is put into operation
(see section 8.5.2 Start sequence of the
section 8.5.3 Stop sequence of the
occurred. The status messages are sent to the higher-level control system
and are displayed on the CDP control panel of the drive.
For information on other status messages, such as fault status messages
in particular, see the status words in the Signal and parameter table of
the drive.
NotReadyOn means that the DC link cannot be charged and the drive
cannot be connected to the main power supply, ie, the main circuit breaker
cannot be closed. The status message is displayed, eg, when the doors of
medium voltage compartments are still open, the grounding switch of the
drive is in the grounded position, or the motor starter of the fan unit is
switched off.
The status message signals that the drive is healthy and ready for the ON
command. The ON command initiates charging of the DC link capacitors
and closing of the main circuit breaker of the drive. Depending on the
control place, the command can either be sent from the higher-level
control system to the drive or be initiated by pressing the SUPPLY ON
pushbutton on the control compartment door.
The status message ReadyOn changes to Charging when the DC-link
capacitors of the drive are being charged.
The message ReadyRun tells the operator that the drive is energized and
ready for operation. As soon as the start command is initiated, the motor
is magnetized and the drive starts to modulate.
When the drive is in ReadyRef state, it is running and operating according
to the set speed or torque reference value. When in remote control mode,
the reference value is set at the higher-level control system. When in local
control mode, the value is entered into the CDP control panel.
Stopping indicates that the drive has received a stop command and that
a ramp or coast stop has been initiated. The stopping mode depends on
the parameter setting. The status message changes to ReadyRun when
the zero speed threshold is reached.
When a start command is given while the drive is stopping, the drive
resumes operation and the status message changes to ReadyRef again.
