NotReadyOn
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.
ReadyOn
The drive is healthy and ready for the ON command. The ON
command initiates charging of the DC link capacitors and the
closing of the main circuit breaker of the drive. Depending on the
control location, 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.
Charging
The status message ReadyOn changes to Charging when the DC
link capacitors of the drive are being charged.
ReadyRun
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.
ReadyRef
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 higher-level control system. When in
local control mode, the value is entered into the
CDP control panel.
Stopping
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.
Tripped
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.
