The DR8010 is a single axis stepper motor driver. It can drive motors with up to 80 volts for excellent high speed performance. The DR8010 driver can be used in conjunction with the OptiStep Plus, MN100 or MN400 motion controllers or with any controller capable of producing TTL compatible step and direction signals. Phase current is switch selectable from 32 different levels ranging from 0.7 to 10.0 amps in 0.3 amp increments.
