00-09 Energy Saving Gain
Control
FOCPG
mode
Settings
When Pr.00-19 is set to1, this parameter can be used for energy saving. The setting should be
decreased when the energy saving is not well. When the motor is vibrated, the setting should
be increased.
00-10 Control Method
Control
VF VFPG
mode
Settings
This parameter determines the control method of the AC motor drive:
Setting 0: user can design V/f ratio by requirement and control multiple motors simultaneously.
Setting 1: User can use PG card with Encoder to do close-loop speed control.
Setting 2: To have optimal control characteristic by auto-tuning.
Setting 3: To increase torque and control speed precisely. (1:1000)
Setting 4: To increase accuracy for torque control.
00-11 V/f Curve Selection

mode
Settings
When it is set to 0, the V/f curve setting for the motor 1 is according to Pr.01-01~Pr.01-08 and
Pr. 01-35~01-42 are for the motor 2.
When setting to 1 or 2, the settings of the 2
are invalid.
