Pulse output: stop (bit 3) 1
(bit 2, fixed) 0
Count: permit (bit 1) 0
I

Reset elapsed value to 0: yes (bit 0) 1
NOTE
• Performing a forced stop may cause the elapsed value at the PLC output
side to differ from the elapsed value at the motor input side. Therefore, you
must execute a home return after pulse output has stopped.
• Setting the near home input is not possible if counting is prohibited or if a
software reset is performed.
