No. Name and function
PA03 Absolute position detection system
Turn off the power and then on again, or reset the
controller after setting the parameter to validate the
parameter value.
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
Turn off the power and then on again, or reset the
controller after setting the parameter to validate the
parameter value.
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.
