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.

01 - 23 Accel/Decel Time Unit

Settings

00: Unit is 1 Sec

 

01: Unit is 0.1 Sec

 

02: Unit is 0.01 Sec

This parameter sets the resolution of accel/decel time (Pr.01-09 to 01-18).

A high resolution decreases the accel/decel time range as shown in the following chart.
