VFD-F Series

5-7

01 - 19

JOG Frequency



Factory Setting: 6.00

Settings 0.0 Hz~120.00 Hz Unit: 0.1sec

 When the JOG function is to be utilized, users need to use the multi-function input terminals (Pr.

04-00 to 04-07 set to 07) or the JOG key on keypad. Once a JOG command is initiated, the AC drive

will accelerate from the Minimum Output Frequency (Pr.01-05) to the JOG frequency (Pr.01-19).

 The accel/decel time of the JOG operation is determined by the JOG accel/decel speed (Pr.01-17 and

01-18).

 When the drive is in operation, the JOG command is disabled.

01 - 20

S Curve Delay Time in Accel Factory Setting: 0.00

01 - 21

S Curve Delay Time in Decel

Settings 0.00~2.50sec

 These parameters enable the S curve. The longer the S curve time period the smoother the transition

between speeds.

01 - 22

Modulation Index



Factory Setting: 1.00

Settings 0.90~1.20 Unit: 0.1

 This parameter sets the ratio of the Maximum Output Voltage to the input voltage.

 The Maximum Output Voltage (Pr.01-02) is normally limited to the input voltage. With the

Modulation Index parameter, the user is able to increase the output voltage beyond the incoming line

voltage.

 A Modulation Index of 1, defines the Maximum Output Voltage (Pr. 1-02) is equal to the input

voltage.

 A Modulation index of 1.2, defines the Maximum Output Voltage (Pr. 1-02) is 20% higher than in the

input voltage. Please note, the output voltage wave form will be distorted due to harmonics and may

increase torque ripple and noise in the motor.
