Symbol Description
P_SSC This is a control mode to drive servo motors by receiving a position
command at a constant period in the synchronous communication with a
controller.
S_SSC This is a control mode to drive servo motors by receiving a speed
command at a constant period in the synchronous communication with a
controller.
T_SSC This is a control mode to drive servo motors by receiving a torque
command at a constant period in the synchronous communication with a
controller.
ct This function enables smooth switching to torque control from the position
control mode or speed control mode without stopping the servo motor.
This eliminates rapid change of speed and torque, contributing to
reduction in load to the machine and high-quality product molding.
