9.6. Status messages
This section lists the messages of the main operating states the drive passes
through, when it is put into operation, when it is stopped, or when a fault condition
has occurred. The 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 “Appendix G
-
Signal and parameter table”
of the drive.
RdyForMCBOn
The status message signals that the drive is healthy and ready for the ON
command. The ON command initiates the charging of the DC-link
capacitors and the 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
Main circuit online push button on the control compartment door.
Charging
The status message
RdyForMCBOn
changes to
Charging
when the DC-
link capacitors of the drive are being charged.
Rdy to Strt
The status message
Rdy to Strt
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.
Magnetizing
The status message
Rdy to Strt
changes to
Magnetizing
when the firing
pulses of the inverter are released.
Running
When the drive is in
Running
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 by 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
Rdy to Strt
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
Running
again.
Discharging
The status message
Rdy to Strt
changes to
Discharging
when the MCB
has opened and the DC-link capacitors are discharging.
Tripped
The status message indicates that a fault condition has occurred that
requires a shutdown of the drive. The status message always alternates
with the specific fault message. The type of shutdown depends on the
fault class the fault condition is assigned to in the drive software.
