If the stop position control command is entered during high-speed operation, a trip may occur because of
overcurrent or overvoltage. To avoid this, do not enter the stop position control command before the motor
enters into low-speed operation.
■ If a trip occurs because of overvoltage when stop position control is performed
If a trip due to overvoltage (OP2 or OP3) occurs when the motor is decelerated by stop position control, reduce the
proportional (P) gain with H to prolong the deceleration time.
Note:The deceleration time setting (FGE) has no effect during stop position control.
