PA10 In-position range
Set the range, where In-position (INP) is output, in
the command pulse unit before calculation of the
electronic gear. With the setting of [Pr. PC24], the
range can be changed to the encoder output pulse
unit.

PA11
PA12 Forward rotation torque limit
Reverse rotation torque limit
The torque generated by the servo motor can be
limited.
When torque is output with the analog monitor
output, the smaller torque of the values in the [Pr.
PA11] (forward rotation torque limit) and [Pr. PA12]
(reverse rotation torque limit) is the maximum output
voltage (8V).
(1) Forward rotation torque limit [Pr. PA11]
Set this parameter on the assumption that the
maximum torque is 100 [%]. Set this parameter
when limiting the torque of the servo motor in the
CCW driving mode or CW regeneration mode.
Set this parameter to "0.0" to generate no torque.
(2) Reverse rotation torque limit [Pr. PA12]
Set this parameter on the assumption that the
maximum torque is 100 [%]. Set this parameter
when limiting the torque of the servo motor in the
CW driving mode or CCW regeneration mode.
Set this parameter to "0.0" to generate no torque.

Forward rotation torque limit
You can limit the torque generated by the servo
motor.
When the torque is outputted with the analog
monitor output, the setting of [Pr. PA11 Forward
rotation torque limit] or [Pr. PA12 Reverse rotation
torque limit], whichever is larger, will be the
maximum output voltage (8 V).
Set the parameter on the assumption that the
maximum torque is 100.0 [%]. The parameter is for
limiting the torque of the servo motor in the CCW
power running or CW regeneration. No torque is
generated when this parameter is set to "0.0".
Setting range: 0.0 to 100.0
PA12 Reverse rotation torque limit
You can limit the torque generated by the servo
motor.
When the torque is outputted with the analog
monitor output, the setting of [Pr. PA11 Forward
rotation torque limit] or [Pr. PA12 Reverse rotation
torque limit], whichever is larger, will be the
maximum output voltage (8 V).
Set the parameter on the assumption that the
maximum torque is 100.0 [%]. The parameter is for
limiting the torque of the servo motor in the CW
power running or CCW regeneration. No torque is
generated when this parameter is set to "0.0".
Setting range: 0.0 to 100.0
