The G902 is a step pulse multiplier for the G320 servo drive that acts like an encoder divider. There are options to change the G902 to 1/10, 1/5, 1/2 and 1/1 of the encoder resolution. This is only beneficial if you have a high resolution encoder and cannot replace it due to motor or design constraints.
There is a jumper block on the G902 that allows the user to select a COMMON +5V (default) or a COMMON GND for the STEP and DIRECTION lines. Using the G902 will turn your G320 into a G340.
For use with G320 servo drives
1, 2, 5 or 10 step pulses out for every input step
Phase-locked loop pulse multiplier
Jumper settable resolution
Optoisolated step and direction inputs
Please Note: The G902 is meant for the G320 only, not the G320X as there is an onboard step pulse multiplier on it already. The G902 requires a G320 to operate and is not a standalone product.
