4.2.42 Jogging (JG) command setting<br />
The jogging command setting function allows you to set and finely<br />
tune the motor-stopping position.<br />
To use this function, assign function "06" (JG) to an intelligent input<br />
terminal.<br />
(1) Jog frequency setting<br />

Since the inverter operates the motor with a full voltage for the jogging operation, the inverter can easily<br />
trip during the latter. Adjust the jog frequency setting (A038) properly so that the inverter will not trip.<br />

Disabling jogging while the motor is operating and<br />
enabling DC braking when the motor is stopped<br />
03<br />
Enabling jogging while the motor is operating and<br />
enabling free-running when the motor is stopped<br />
Enabling jogging while the motor is operating and<br />
04<br />
enabling stopping after deceleration when the<br />
motor is stopped<br />
05 (See Note 2.)<br />
Enabling jogging while the motor is operating and<br />
enabling DC braking when the motor is stopped<br />
Note 1: To perform the jogging operation, always turn on the JG terminal before turning on the FW or RV<br />
terminals. (Follow this sequence of command inputs also when using the digital operator to enter<br />
operation commands.)<br />

When "00", "01", or "02" is specified for the jog stop<br />
mode (A039), the jogging operation will not be<br />
performed if the FW signal is turned on earlier than<br />
the JG signal.<br />

When "03", "04", or "05" is specified for the jog stop mode<br />
(A039), the jogging operation will be performed, even if the<br />
FW signal is turned on earlier than the JG signal. However,<br />
the motor will stop after free-running if the JG signal is turned<br />
off earlier than the FW signal.<br />
Note 2: You must set DC braking data if you specify "02" or "05" for the jog stop mode (A039). (See<br />
Section 4.2.19.)<br />
