Times of auto restarting of inverter shall be set to 10 times after alarm (for alarm allowable situations: OC (over
current) and OV (over voltage)). If it is set to 0, auto-reset/restarting function shall not be performed. In restarting
after alarm, AC motor drive shall be started in speed tracking mode up to down.

Inverter rating generally consists of AC 200V/200V and 60Hz/50Hz; input voltage of inverter ranges from AC 180V to
264V, 50Hz/60Hz; Thus, for inverter without function of auto-voltage stabilizing, if input power supply of motor is AC
250V, a same voltage shall be output to motor, and motor shall then run in a power supply which is 12%-20% more
than rated voltage. This will cause an increased temperature rise to motor. This shall also be unfavorable to
insulation and torque output, thus, duration of motor shall be decreased sharply as a result.
Auto-voltage stabilizing function of inverter shall stabilize automatically output power supply to rated voltage of motor
when input power supply exceeds rated voltage of the motor. For example, if V/f curve is set to AC 200V/50Hz and
input power supply is in a range of AC200 ~264V, voltage output to motor shall be stabilizing automatically to AC
200V/50Hz, not exceeding the set voltage. If input power supply varies from AC 180 to 200V, voltage output to motor
shall be proportional to input power supply.
It has been discovered that in deceleration to stop, time of deceleration shall be decreased when AVR function is
closed. In addition with fine function of auto acceleration and deceleration, the accel/decel of motor shall be much
more speeded.

Auto-reset(Counter clear time): every retry (including the waiting period before retry) will make the time of fault restart
minus 1. The inverter will not restart automatically when the alarm restart time has been decreased to 0. If OU and
OC alarm don’t happen in the time set by 8-20, the time of alarm restart will set to the time set by 8-14 automatically.

It is the waiting time for alarm restart, which means the restart command will be performed after the time set by this
parameter when alarm happens.
