■
EM1 (Forced stop 1)
When EM1 is turned off (open between commons), the base circuit shuts off, and the dynamic brake operates to decelerate
the servo motor to a stop.
The forced stop will be deactivated if EM1 is turned on (short between commons) while in the forced stop state.
■
LSP (Forward rotation stroke end)/LSN (Reverse rotation stroke end)
To operate a servo motor, turn on LSP/LSN. Turn LSP/LSN off to bring the servo motor to a stop and switch it to the servo-lock
state.
For information about areas such as the supported control modes, automatic on, and restrictions, refer to "Stroke limit
function" in the following manual.

■
PC (Proportional control)
Turn PC on to switch the speed amplifier from the proportional integral type to the proportional type.
If a servo motor is rotated even for a pulse due to any external factor while it is at a stop, it generates torque to compensate for
a position mismatch. If locking the servo motor shaft mechanically after positioning completes, turn on PC (Proportional
control) upon completion of positioning to suppress the unnecessary torque generated for compensation of a position
mismatch.
If locking the shaft for a long period of time, set the torque value to be the rated torque or less.
Do not use PC in the torque mode. If PC is used in the torque mode, the servo motor may operate at a speed exceeding the
speed limit value.
■
CDP (Gain switching)
Turn on CDP to use the values of [Pr. PB29] to [Pr. PB36] and [Pr. PB56] to [Pr. PB60] as the load to motor inertia ratio and
individual gain values.
When both CDP and CDP2 are on, the setting of CDP2 is prioritized.
■
CDP2 (Gain switching 2)
Turn on CDP2 to use the values of [Pr. PB67] to [Pr. PB70] as the load to motor inertia ratio and individual gain values.
When both CDP and CDP2 are on, the setting of CDP2 is prioritized.
■
DOG (Proximity dog)
Turning off DOG will detect a proximity dog. The polarity for the proximity dog can be changed with [Pr. PT29.0].
