1. FEATURES
• Single Axis Driver with indexer for Bipolar step motors
• Encoder readout function available
• 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).
