7.9.2 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.
→ For the parameters, control data and monitor data, refer to Chapter 11
1. Set as follows when using the servo end check.
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."
