Servo end check function

Use the servo end check function to detect the positioning operation completion by the servo status in-
position signal. When the servo status in-position signal turns ON after operation completion (within the range
of servo end check determination time) the 20SSC-H detects that the positioning operation has ended.
When the in-position signal does not turn ON within the specified servo end determination time, an external
error occurs, stopping the operation.
1. Set as follows when using the servo end check.
Servo end check
enabled/disabled
Servo end evaluation time
In-position
In-position range
Servo end evaluation time
When the set value of the servo end evaluation time is outside the setting range, the set value is handled as
follows:
• Zero or smaller settings are handled as "1ms."
• 5001 or larger settings are handled as "5000ms."
2. Applicable positioning operations

This parameter sets the evaluation time for the servo end check.
Setting range: 1 to 5000 ms
This bit is set while droop pulses are within a range of "In-
position."
Set the range to output a positioning completion signal in units of
command pulses.
Setting range: 0 to 65535 PLS
• Operations inapplicable to the servo end check
- During continuous multi-speed operation
- During continuous pass operation of
interpolation operation
- Manual pulse generator operation
