DI0 CN1B The following table lists the point table numbers that may be chosen by the
5 combinations of DI0, DI1, DI2, DI3 and DI4.

Note. 0: DI0/DI1/DI2/DI3/DI4-SG off (open)
OVR Short OVR-SG to make override (VC) valid.
TL Short TL-SG to make external analog torque limit valid.
For more information, refer to section 3.4.4.
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.
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).
