1. FEATURES

• Single Axis Driver for Bipolar step motors

• Operates from +12 to 48 VDC

• Phase currents from 0.3 to 3.0 Amp Peak

NOTE: Phase current of 2.7 Amp and above REQUIRES an additional heatsink,

make sure the temperature of the bracket does not exceed 45° C.

• Hold current reduction capability with adjustable current and timeout settings

• Selectable Step Resolution from Full Step to 256x Microstepping

• Has three optically isolated control inputs and one optically isolated control output

• Pole Damping Technology™ integrated within driver board

Dip switches and a RS485 interface are built-in to the R325P Controller. A USB connection can

be used by using the USB485 Converter Card (sold separately).
