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 indicates that the drive has received a stop command and that
a stop ramp, stop torque or coast stop has been initiated. The stopping
mode depends on the setting of parameter 21.02, STOP FUNCTION. The
status indication 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 indication changes to ReadyRef again.
This 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 that the fault condition is assigned to in the drive software.
