1. After power-on, the drive indicates the status "Drive ready" by setting digital output
DO1 to HIGH level.
2. After controller enable, the positioning program is started by setting digital input DI6
to HIGH level.
3. The table traverses upwards until reaching the home switch.
– The home switch is 10 mm above the start position and connected to digital input
DI2.
4. After the homing mark has been detected, the table traverses downwards until
reaching the start position (first pick-up position).
5. The drive indicates the status "Homing completed/table in start position" by setting
digital output DO2 to HIGH level.
6. The internal sheet counter is reset to zero and stacking can start.
7. When a sheet has been added, digital input DI8 changes to HIGH level.
– After this, the table is lowered by one sheet thickness each.
8. 10 sheets can be piled up before the drive indicates the status "Maximum number of
sheets reached" by setting digital output DO3 to HIGH level.
– Then, the stack must be removed.
9. After the stack has been removed and digital input DI6 has been set to HIGH level, the
table traverses back to the start position (first pick-up position).
– A new stacking process can be started.
