ABB ACS5000 User Manual page 120

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.
