Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual page 84

Restrictions
• Always limit the servomotor torque after the speed reaches the speed set in [Pr.47] Creep speed. Otherwise the servomotor
may be damaged when the workpiece hits the stopper. (Page 230 Torque limit function)
• Use an external input signal as a zero signal.
Precautions during the operation
• Input a zero signal from an external source after the workpiece hits to the stopper. If a zero signal is input before the
deceleration to the speed set in [Pr.47] Creep speed is completed, the machine will continue decelerating and stop and
Zero signal detection timing fault (Error code: 1942H) will occur.
