Frequently Asked Questions

Who should operate or install the PositionServo drive?

All operations concerning transport, installation, commissioning, and maintenance must be carried out by qualified, skilled personnel.

What is the maximum number of variables that can be manipulated at once using array functions?

The function supports up to 10 variables (array elements).

How do I read multiple run-time variables as 32-bit integers?

Use SS940_GetArrayAsInteger, providing the interface handle, an array of variable indexes, and the count.

Are the drive controllers safe for use in residential settings?

No, these products can cause radio interference in residential areas.
