by P93.01, the brake failure fault (bE) is reported.
For details, see the torque verifying and brake slip
descriptions in the brake function commissioning
section.
P93.02
Zero servo
protection mode
The zero servo function is applied in the
closed-loop vector control mode. When P93.02=1,
the zero servo input slows down, the load is slowly
put on the ground in zero servo state. When
P93.02=2, the motor is locked to the stopped
state, which indicates that the VFD keeps the
motor in the position where the motor stops even if
external force is applied to the motor.

–2
0: Disable zero servo
1: Zero servo input slows down
2: Zero servo input is always valid (keep running at
zero speed)

Note:
•
When certain faults (that cannot be reset, such
as VFD internal hardware damage) occurred, the
zero servo state cannot be entered. When other
faults (that can be reset) occurred, the zero servo
state can be entered when the zero servo
condition is met.
•
Every time the zero servo state is exited, torque
verification is not performed for the first given
running command, but it is performed for the later
given running commands.
