No. Name and function
PC01 Error excessive alarm level
This parameter cannot be used in the speed control
mode or in the torque control mode.
Set error excessive alarm level with rotation amount of
servo motor.
Note 1. Setting can be changed in [Pr. PC06].
2. For a servo amplifier with software version of B2
or later, reactivating the power supply to enable
the setting value is not necessary. For a servo
amplifier with software version of earlier than B2,
reactivating the power supply is required to
enable the setting value.
Check the software version using Setup software
(SETUP221E).
PC02 Electromagnetic brake sequence output
Used to set the delay time (Tb) between electronic brake
interlock (MBR) and the base drive circuit is shut-off.
PC03 Encoder output pulse selection
Use to select the, encoder output pulse direction and
encoder output pulse setting.

value
3 PC01 Error excessive alarm level
Set an error excessive alarm level.
Set this per rev. for rotary servo motors and direct drive
motors. Setting "0" will be 3 rev. Setting over 200 rev will
be clamped with 200 rev.
0 PC02
Same as MR-J3
Electromagnetic brake sequence output
This is used to set the delay time between MBR
(Electromagnetic brake interlock) and the base drive
circuit is shut-off.

Encoder output pulse selection
This is used to select the encoder pulse direction and
encoder output pulse setting.
