Motor Adaptation, AMA and drive performing adaptation function.
BRAKE CHECK OK Brake check function is completed and brake resistor and transistor
tested successfully.
BRAKING Drive brake is functioning and motor is being slowed.
BRAKING MAX Drive brake functioning at maximum. Drive brakes to its maximum
when running 100% duty cycle.
CATCH UP Drive output frequency increased by percentage value selected in
parameter 219,
Catch up/Slow down Value .
CONTROL READY Condition causing UNIT NOT READY status has been rectified and
drive is ready for operation.
CURRENT HIGH Warning of drive output current higher than value set in parameter
224,
