14.34.2.4 Operation Function: Incremental Feed

The axis is moved by the designated amount.
Turning Operation start (ST) ON feeds the axis by the constant amount.
Preparation
Set the following signals before operation.
Abbreviation Signal name
S Incremental mode
DIR Rotation direction
PR1, PR2 Operation parameter selection 1, 2
MP1, MP2 Incremental feed magnification 1, 2 Select the feed amount per movement.
Operation
Turn ON Operation start (ST). If this signal is turned OFF during the movement, the axis moves for the designated feed
amount before stopping.

Smoothing zero (SMZ)
Note
(1) When the torque limit value of the operation parameter group selected at turning-ON of operation start is set to "0", the
operation error (M01 0167) occurs and the axis movement by the incremental feed operation cannot be performed.
IB-1501668-B
Use this signal to select incremental mode.
Setting two different operation modes at the same time will cause the oper-
ation error (M01 0101).
Parameter "#1018 ccw" also reverses the rotation direction.
Accelerated/decelerated will be carried out with the accelerate/decelerate
time constant of selected operation group.
Value at ST's ON is valid
Available only at rising edge
