Part 3: Review on Replacement of MR-J3-_B_ with MR-J4-_B_
No. Name and function
PA03 Absolute position detection system
This parameter is made valid when power is switched off,
then on after setting, or when the controller reset has
been performed.
This parameter cannot be used in the speed control
mode.
Set this parameter when using the absolute position
detection system in the position control mode.
0 0 0 x:
Selection of absolute position detection system
0: Used in incremental system
1: Used in absolute position detection system
PA04 Function selection A-1
This parameter is made valid when power is switched off,
then on after setting, or when the controller reset has
been performed.
The servo forced stop function is avoidable.
0 x 0 0:
Selection of servo forced stop
0: Valid (Forced stop (EM1) is used
1: Invalid (Forced stop (EM1) is not used.)
When not using the forced stop (EM1) of servo amplifier,
set the selection of servo forced stop to Invalid (_ _1_).
At this time, the forced stop (EM1) automatically turns on
inside the servo amplifier.
