Figure 2-18. OEM650 Inputs & Output Schematic
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.
