Exceeded negative side hardware OT. This alarm is generated when the machine reaches the stoke end. When this alarm is not generated, feed of all axes is stopped during automatic operation. During manual operation, only the feed of the axis on which the alarm occurred is stopped. Check 24v to overtravel limit switch. Move off hard limit switch. The signal is active low requiring 24v applied to deactivate so loss of 24v or tripping switch causes the alarm.
