Description of the control programs
Operating and Programming 63
PII - Motor States (Speed 1 - 4)
Motor Conveyor RollerDrive
Homing:
During operation of the HPD, a rotation of the carrying rollers relative to the zero position may
occur. The HPD must therefore refer to itself from time to time and possibly correct the position of
the conveyor rollers (Homing).
The input byte "Motor Speed 1" indicates the value 127. When the zero position is reached, the
value 0 is displayed.
Value 127 = HPD adjusting to zero position (Homing straight, 0).
We recommend performing the initialization periodically (e.g. every minute) when
the HPD is at or near the zero position and there is no conveying for about two
seconds, as the process will then take less than 200 ms. If a Homing is started in
another position, the process could take seconds.
It is only possible to start a new Homing run every 30 seconds.
Homing may only be started if the HPD is between +80 und -80, otherwise correct
Homing cannot be performed.
What happens during Homing??
1. If sensor 1 = 0: Motor turns left until Sensor 1 = 1 (ready).
2. If sensor 1 = 1: Motor turns right until Sensor 1 = 0
Motor turns back left until Sensor 1 = 1 (ready).
