DP lift motor going up error |
DP lift motor. DP lift sensor 1. DP main PWB. |
| When the DP lift motor is driven, DP lift sensor 1 does not turn on within 1500 pulse. (Three recovery times.) The above has been detected 5 times. * The number of detection should be weighted with one for the rise at job start and two for the irregular rise during transpoting. The accumulated number must be cleared at completion of a normal rise. The default threshold is 5. |
