Proportional
control
PC Turn PC on to switch the speed amplifier from the proportional integral
type to the proportional type.
If the servo motor at a stop is rotated even one pulse due to any external
factor, it generates torque to compensate for a position shift. When the
servo motor shaft is to be locked mechanically after positioning
completion (stop), switching on the PC (Proportion control) upon
positioning completion will suppress the unnecessary torque generated to
compensate for a position shift.
When the shaft is to be locked for a long time, switch on the PC
(Proportion control) and TL (External torque limit selection) at the same
time to make the torque less than the rated by TLA (Analog torque limit).
