Check if the home stop position shifts by repeating the JOG and home return operations.
Procedure 4
If the home stopping position is shifted, change the position of near home input or reduce the
home return speed.
6.3.5 Checking Rotating and Moving Directions and Moving Distance
Procedure 1
Execute the JOG operation to confirm the rotating direction and moving direction of the motor.
Use the tool operation function of CMI and perform the JOG operation.
Points to check
The rotating direction is determined according to the installation of the ball screw or the
"CW/CCW direction setting" of the axis parameter.
Procedure 2
Check if the moving distance is that as designed by performing the JOG operation or
positioning operation.
Points to check
The moving distance is determined according to the pitch of the ball screw, deceleration gear
