One the enclosed drives ATV31C and ATV320W series drives there is an option for a ZH28 version.
There is not a data sheet for this version of drive as it is modified after it leaves the factory.
The nearest data sheets would be for the standard items ATV31C version drives and the ATV320W version drives.
The ZH28 modification gives you the following items added to the standard item.
A main switch disconnector from the Vario rotary switch range, sized for the drive rating.
A potentiometer added to the front cover for the local speed control option.
A three position stay put selector switch for the off forward and reverse options, but as default only the run forwards is pre-wired.
These switches would be pre-wired from the front door to the main drive control terminals, the three position switch would have the +24 to DI1 connected only for run forwards only ( although the three position switch is fitted ) But the reverse can be easily added by looping the +24 to the other contact block on the switch and a wire being bought back to the DI2 input.
The potentiometer would be pre-wired across the +10, AI1 and com terminals for the local speed control.
This is how these drives would come from being ordered. The closest data sheets would be as the standard catalogue part codes for the ATV31C drives and the ATV320 W version drives, with the XB5AD33 selector switch fitted, the XB5AD912R4K7 potentiometer type fitted, and the Vario isolator range fitted and pre-wired.
