Acceleration/deceleration 0.01 to 6000 sec. Selectable from among acceleration/deceleration. times 1 and 2. Automatic
time acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 pattern adjustable.
Adjustment of braking start frequency (0 to 120Hz), braking (0 to 100%) and braking time (0 to 20 sec.).
DC braking
With emergency stop braking function and motor shaft fix control function.
Forward run/reverse run With F-CC closed to forward run, with R-CC closed to reverse run, with both closed to reverse run. With
[Note 1] ST-CC opened to coast stop. Emergency stop by panel operation or terminal board.
Jog run Jog mode, if selected, allows jog operation from the operation panel
[Note 1] Jog run operation by terminal board is possible by setting the parameters.

operation.
[Note 1]
Selectable between acceleration/deceleration time, torque limit and V/f by set frequency.
Capable of restarting after a check of the main circuit elements in case the protective function is activated.
Retry
Max. 10 times selectable arbitrarily. Waiting time adjustment (0 to 10 sec.)
Soft stall Automatic load reduction control at overloading. (Default: OFF)
Cooling fan ON/OFF The cooling fan will be stopped automatically to assure long life when unnecessary.
Operation panel key Key prohibition selectable between STOP key only, MODE key only, etc. All key operations can be
operation ON/OFF control prohibited.
Regenerative power ride- Possible to keep the motor running using its regenerative energy in case of a momentary power failure.
through control (Default: OFF)
Auto-restart operation Possible to restart the motor in coasting in accordance with its speed and direction. (Default: OFF)
Commercial inverter Possible to switch operation by commercial power source or inverter
switching
When two or more inverters are used to operate a single load, this function prevents load from
