Description
than P93.05. If yes, the VFD reports the holding
brake failure alarm A-bS, and the alarm can be
configured with relay action output.
After reporting A-bS, it selects an action
according to the ones place of P93.02 after the
delay time specified by P93.06 (if the pulse
value during this period is greater than 3 times
the value specified by P93.05, this delay time
P93.06 is skipped:
1. If P93.02 ones place=1, the motor runs down
slowly at the frequency specified by P93.03,
after the time specified by P93.04 elapses, the
motor coasts to stop and performs detection
again. This process will be repeated.
2. If P93.02 ones place=2, the running is kept at
zero speed.
3. If P93.02 ones place=3, the motor keeps
zero speed running for a period specified by
P93.07, and later it automatically switches to
the zero speed slow lowering down mode.

1: Enable internal measuring (motor encoder)
2: Enable external measuring (HDI)
Note: When P93.08=2, P20.15=0 indicates
HDI measuring the height.
For internal measurement (motor encoder), the
encoder is mounted on the motor shaft, and
P93.09 is the reduction ratio between the motor
shaft and drum shaft.
For external measurement (HDI), P93.09 is the
