Positioning jobs

After switching on the operating voltage, it must be waited
until the CMAX is completely installed, signals no error
(see Fig. 4/1) and delivers the inputs SCON.ENABLED and
SCON.OPEN logic 1. Afterwards, the corresponding positionĆ
ing job can be executed via the control bytes (module outĆ
put data) (see section 4.5 and the CMAX communication
profile" description).

Homing after POWER ON

Only with incremental position measuring systems:
After the CMAX operating voltage is switched on again, the
relationship between measured variable and current position
is lost. For that reason, homing must always be carried out
after switching on again.

After switching on the power supply, only the positioning
commands homing (CPOS.HOM), jog (CPOS.JOGx) and the
movement test are permissible for incremental displacement
encoders. Other positioning commands lead to error E10
(Drive is not referenced").
