[Cause]
Pressure equalizing cannot be performed in the current posture. During pressure equalizing, at least one of the J1, J2, or J3 axes must have sufficient sensitivity to the reaction force from the workpiece. This alarm indicates that none of these axes has sufficient sensitivity. The number in parentheses indicates the motion group number.
