Constant/Variable Torque Selection
Control
mode
VF VFPG SVC FOCPG
Factory setting: 0
Settings 0 Constant Torque (150%)
1 Variable Torque (120%)
 When “1” is selected, the oL level is 120% of rated drive current. All other overload
ratings will not change, example: 150% of rated drive current for 60 seconds.

Optimal Acceleration/Deceleration Setting
Control
mode
VF VFPG SVC FOCPG
Factory setting: 0
Settings 0 Linear accel./decel.
1 Auto accel., linear decel.
2 Linear accel., auto decel.
3 Auto accel./decel. (auto calculate the accel./decel. time by actual load)
4 Stall prevention by auto accel./decel. (limited by 01-12 to 01-21)
 It can decrease the drive’s vibration during load starts and stops by setting this
parameter. Also it will speed up to the setting frequency with the fastest and smoothest
start-up current when it detects small torque. At deceleration, it will auto stop the drive
with the fastest and the smoothest deceleration time when the regenerated voltage of
the load is detected.
