27 Encoder output pulses
Used to set the encoder pulses (A-phase and B-phase)
output by the servo amplifier. Set the value 4 times
greater than the A-phase and B-phase pulses.
[Pr. 58] can be used to choose the output pulse setting or
output dividing ratio setting.
The number of A-phase and B-phase pulses actually
output is 1/4 times greater than the preset number of
pulses.
The maximum output frequency is 1.3 Mpulse/s (after
multiplication by 4). Use this parameter within this range.
• For output pulse designation
Set [Pr. 58] to "0 _ _ _" (initial value).
Set the number of pulses per servo motor revolution.
Output pulse = setting value [pulse/rev].
For instance, when "5600" is set, the actual output A-
and B-phase pulses are as follows.
Phase A/phase B output ulse =

5600
=1400 [pulse]
• For output division ratio setting
Set [Pr. 58] to "1 _ _ _".
The number of pulses per servo motor revolution is
divided by the set value.
Output pulse =

28 Internal torque limit 1
Limit the servo motor torque assuming that the maximum
torque is 100%.
When "0" is set, no torque is generated.
Setting range: 0 to 100 100 100 PA11 Forward rotation torque limit
You can limit the torque generated by the servo
motor.
Set the same value as for MR-J2S-_CP_. 100.0
PA12 Reverse rotation torque limit
You can limit the torque generated by the servo
motor.
Set the same value as for MR-J2S-_CP_. 100.0
29 Internal torque limit 2
Limit the servo motor torque assuming that the maximum
torque is 100%.
When "0" is set, no torque is generated.
Enabled by turning on the internal torque limit selection
(TL2).
Setting range: 0 to 100 100 100 PC35 Internal torque limit 2
Used to set the parameter assuming that the
maximum torque is 100.0%. Set for limiting the
torque of the servo motor.
However, when "0.0" is set, no torque is
generated.
Turning on TL1 (Internal torque limit selection)
will enable the lower torque limit between the
Internal torque limit 1 or 2.
Setting range: 0.0 to 100.0 100.0
