Servo Off Codes; Emergency Stop - Haas+Sohn HRT 160 Operator's And Service Manual

0 too SL (Zero margin too small) Zero margin too small is the distance between the home switch
and the final stopped motor position, after seeking home, is either less than 1/8 or greater
than 7/8 of a motor revolution.
This alarm may occur while homing the rotary table. The distance between the home switch and the final motor
position at zero is less than 1/8 of a motor revolution. To prevent this alarm, parameter 45 must be set properly.
Start with the default value for parameter 45 (0) and add 1/2 of a motor revolution (1/2 motor revolution is equal
to the value in parameter 28 divided by 2). Home the rotary table after the new value for parameter 45 has been
entered.
There are no user-serviceable parts inside, so refer all problems to HAAS Automation for
repair.

Pushing the EMERGENCY STOP button will turn the servo off and cause the spindle to decelerate and stop.
Position will not be lost. If the step was not completed you will still be on that step. Push CYCLE START to
turn the servo on. The remote cycle start and cycle finish will not function until the EMERGENCY STOP is
removed by pushing the START button. If an EMERGENCY STOP is performed, the display will indicate an:
E-StoP
CE machines have an Emergency-stop switch on the top of the control. Pressing the E-stop switch will turn off
the servo and aborts the step in progress.
