ABB ACS5000 User Manual page 126

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 push
button 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.
