ZERO SEARCH
After any power-on of the control unit (24V DC auxiliary supply) the turret must execute the reference
cycle.
At the end of the reference cycle the turret is locked in position 1.
To execute the reference cycle proceed as follows
1. Set an automatic function (1,2 or 3)
2. Set this code.
POSITION PARITY PBIT01 PBITO2 PBIT04 PBIT08 (PBIT16)
Zero cycle
0 0 0 0 0 0
3. Set impulsive PSTART to reach out the zero position
(PSTART must stay on for more than 30 ms).
4. Wait 500 ms after INDEXD and LOCKED signals give the end of the cycle.
