Manual Operation Mode; Jog Operation - Mitsubishi Electric MELSERVO-J4 Instruction Manual

5. HOW TO USE THE PROGRAM

5.3 Manual operation mode

For the machine adjustment, home position adjustment, and others, you can shift the position to any position
with a JOG operation or manual pulse generator.

5.3.1 JOG operation

(1) Setting
According to the purpose of use, set input signals and parameters as shown below. In this case, DI0
(Program No. selection 1) to DI3 (Program No. selection 4) are invalid.

(2) Servo motor rotation direction
ST1: on
Forward rotation (CCW)
(3) Operation
When ST1 is switched on, the servo motor rotates using the JOG speed set by the parameter and the
acceleration/deceleration constants set by [Pr. PC02] and [Pr. PC03]. For the rotation direction, refer to
(2) of this section. Switching on ST2 rotates the servo motor opposite to the direction of ST1 (Forward
rotation start).
