6. APPLICATION FUNCTIONS
6.10 Interlock
When the interlock signal (ITL) is turned on, movement is temporarily stopped. During stoppage of movement
the interlock stop signal (ISTP) is turned on. When the interlock signal (ITL) is turned off, operation is resumed.
The interlock signal (ITL) for normally-open contact or normally-closed contact can be selected using control
option 3 (parameter No.0202). (The explanation in this section is for a normally-open contact.)
When using interlock to stop the servo, deceleration uses the rapid stop time constant.

If the interlock signal is cancelled during deceleration, operation is re-started after the command speed
decreases to 0. For this case, the interlock stop signal (ISTP) does not turn on.
