PC01 ERZ Error excessive alarm level
This parameter cannot be used in the speed control mode.
Used to set the error excessive alarm level in mm unit.
When "0" is set in this parameter, the alarm level is 3mm. When a value other
than "0" is set, the alarm level is the amount of the set value. However, the alarm
level stays at 200mm even if a value exceeding "200" is set.
Note. Setting can be changed in parameter No.PC06. Each
