Step Input Signal Specification

The OEM650's inputs are optically isolated and may be driven (activated) by providing a positive pulse to the plus input with respect to the minus input. This input may also be differentially driven. The input driver must provide a minimum of 6.5 mA— approximately 3.5 VDC (15 mA maximum).

Step Pulse Input

Operate the step pulse input within the following guidelines:

❏200 nanosecond-pulse minimum

❏40% - 60% duty cycle (2 MHz maximum pulse rate

Direction Input Signal Specification

The OEM650's inputs are optically isolated and may be driven (activated) by providing a positive pulse to the plus input with respect to the minus input. The input may also be differentially driven. The input driver must provide a minimum of 10 mA— approximately 3.5 VDC—to ensure adequate operation.

Direction Input

The direction may change polarity coincident with the last step pulse. The direction input must be stable for at least 120 µsec before the drive receives the first pulse.
