Parameters
Fig. 5-58:
● The pulses are slow during motor acceleration. The pulses are fast at full speed. The pulses become
slower during deceleration, and eventually becomes 0 and the motor stops a little after the
command pulse. This time difference is necessary to ensure stop accuracy and is called stop
setting time.
NOTES To assign the servo ON signal (LX), set "23" in any of Pr. 178 to Pr. 189 (input terminal function
selection).
To assign the positioning completion signal (Y36), set "36" in any of Pr. 190 to Pr. 196 (output ter-
minal function selection).
Changing the terminal assignment using Pr. 178 to Pr. 189 or Pr. 190 to Pr. 196 may affect other
functions. Set parameters after confirming the function of each terminal.
