Decremental
Example:
When the current position (value of elapsed value area) is 5000, the pulse of 1000 is output from CW by
executing the pulse output instruction with the target value +1000, and the current position will be 6000.
Absolute <Absolute value control>
Outputs a number of pulses equal to the difference between the set target value and the current value.

Example:
When the current position (value of elapsed value area) is 5000, the pulse of 4000 is output from CCW
by executing the pulse output instruction with the target value +1000, and the current position will be
1000.
Home return
• When executing the F171 (SPDH) instruction, the pulse is continuously output until the home input
(X102 or X202) is enabled.
• To decelerate the movement when near the home position, designate a near home input and set bit 4
of special data register DT90052 to off → on → off.
• The deviation counter clear output can be output when home return has been completed.
JOG operation
• Pulses are output from the specified channel while the trigger for F172 (PLSH) instruction is in the ON
state. Also, the pulse output can be stopped when the specified target value is matched.
• The direction output and output frequency are specified by F172 (PLSH) instruction.
