OEM650 Inputs & Output SchematicStep Input Signal SpecificationThe OEM650's inputs are optically isolated and may be driven(activated) by providing a positive pulse to the plus input withrespect to the minus input. This input may also be differentiallydriven. The input driver must provide a minimum of 6.5 mA—approximately 3.5 VDC (15 mA maximum).Step Pulse InputOperate the step pulse input within the following guidelines:❏ 200 nanosecond-pulse minimum❏ 40% - 60% duty cycle (2 MHz maximum pulse rateDirection Input Signal SpecificationThe OEM650's inputs are optically isolated and may be driven(activated) by providing a positive pulse to the plus input withrespect to the minus input. The input may also be differentiallydriven. The input driver must provide a minimum of 10 mA—approximately 3.5 VDC—to ensure adequate operation.Direction InputThe direction may change polarity coincident with the last steppulse. The direction input must be stable for at least 120 μsecbefore the drive receives the first pulse.
