Status messages

The following section lists the status messages of the main operating
states that the drive passes through when:
• Drive is put into operation
• Drive is stopped
• Fault condition has occurred
The status messages are sent to the higher-level control system and are
displayed on the control panel of the drive. For information on other
status messages (eg, fault status messages), see the status words in
"Appendix G – Signal and parameter table".
Not ready to switch on
The DC link cannot be charged and the drive cannot be connected
to the main power supply (that is, the main circuit breaker cannot
be closed). The status message is displayed, when the doors of
medium voltage units 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.
Ready to switch on
The drive is healthy and ready for the ON command. The ON
command initiates charging of the DC link 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 SUPPLY ON
push button on the control compartment of the drive.
Charging
Ready run
Informs 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.
Ready ref
The drive 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 remote control system. When in local
control mode, the value is entered into the control panel.
Stopping
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 "Ready run" 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
"Ready ref" again.
