Override selection

OVR

Short OVR-SG to make override (VC) valid.

External torque limit
selection

TL

Short TL-SG to make external analog torque limit valid.
For more information, refer to section 3.4.4.

Internal torque limit
selection

TL2

Open TL2-SG to make the torque limit value set in parameter No.28 (TL1) valid, or
short them to make the value set in parameter No.29 (TL2) valid.
For more information, refer to section 3.4.4.

Proportion control

PC

Connect PC-SG 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. In such a case where the axis

will be locked mechanically after Movement finish (MEND) has turned off, turning

Proportion control (PC) on as soon as Movement finish (MEND) turns off can
suppress unnecessary torque that attempts to compensate for a position shift.
When the shaft is to be locked for a long time, switch on the proportion control (PC)
and torque (TL) at the same time to make the torque less than the rated by the
analog torque limit (TLA).
