Not a compulsory item

Specify the reverse traveling amount taken in the direction opposite to the starting direction for homing

at the start of homing motion.

If a reference signal for homing (deceleration starting signal) or reference signal for shift operation is

detected during reverse travel, movement toward the homing direction after reference signal detection

begins. Use the setting to reduce the homing time.

4

Use if the stopping position is in the direction opposite to the starting direction for homing and the

maximum distance from the stopping position to the zero position is always known.

The unit amount depends on PA1_06 (numerator 0 of electronic gear) and PA1_07 (denominator of

electronic gear).

If neither the reference signal for homing (deceleration starting signal) nor reference signal for shift

operation is detected during reverse motion, movement in the starting direction for homing begins after

reverse motion by the preset traveling amount.
