1. FEATURES R701P • 10 microstepping driver • Common Ground or Common + 5 Volts Input Option Available • Optically isolated Step, Direction, and Disable/Enable inputs • Automatic Current Reduction • Adjustable trimpot for noise and vibration reduction • Operates from 18 to 80 VDC •... -
Page 5: Heatsinking
Heatsinking The R701P needs an additional heatsink for current settings greater than 3 Amps. The case temperature (measured from the bottom plate) should not exceed 70° C. For best results, use heatsink compound between the R701P and the heatsink. 4. MECHANICAL SPECIFICATIONS Size: 2.5”... -

Page 7: How To Connect
How to Connect For safety reasons, please connect the power supply (Terminal 2) last. Terminal 1: Power Ground - Connect the power supply ground here. Terminal 2: +18 to 80 VDC - Connect the positive (+) end of the power supply here. The maximum power supply current required is 67% of the motor’s rated phase current. -

These inputs are optically isolated from the rest of the drive. Terminal 10 is the common anode connection for the opto-isolators and must be connected to the +3.3VDC,+5 VDC supply of your indexer or pulse generator. These inputs are meant to be driven by 3.3V to 5.5V logic capable of sourcing or sinking 2.5 mA of current. -
Page 9: Resistor Values For The Opto Supply
Figure 3: Connections Diagram Resistor Values for the Opto Supply The optocouplers must be powered by an external power supply to maintain isolation. The Opto Supply (Terminal 10) for the optocouplers can be between +5 to 24 VDC with respect to the signal input. -

7. CONFIGURING AND CONTROL OF THE R701P Adjust Trimpot This trimpot adjusts the motor for the smoothest possible low speed operation. Set the motor speed to about ¼ revolutions per second, and then, using a flathead screwdriver turn the trimpot until a distinct null is noted in the motor’s vibration. -

Page 12: Main Connector
Main Connector The R701P uses a 2-piece modular main connector. The connector is split into two pieces: Terminals 1 through 6 (power supply and motor leads) and Terminals 7 through 12 (control interface). Each can be removed separately by pulling the connector body upwards and off of the mating header pins on the R701P. -

6 Lead Wire Motor Connection (Full-Winding) For a full winding connection, use both end wires, the center tap is ignored. (NC: No Connection). Figure 5.3: 6 Lead Wire Full Winding Connection 8 Lead Wire Motor Connection (Parallel Connection) Eight wire motors can be connected in two ways: Parallel and Series. When in parallel, the wires are simply connected such that the beginning of each winding are connected together. -

9. TROUBLESHOOTING & FAQ The Motor is in Holding Position, but does not rotate: This means that Power is being supplied to the driver and motor, so the power supply is OK. However, the signal generator might be causing the problem. Try changing the signal to TTL. If this doesn't help, is the external +5 VDC Power connected? Be sure that the step pulses are a 0 to 5V squarewave with even on and off time.
