The STR series stepper drive is a compact,
powerful, digital step and direction drive
available in three power ranges: 2 A/phase, 4 A/phase
and 8 A/phase. The STR series is ideal for
applications requiring basic step and
direction control of a 2-phase step motor.
STR drives feature advanced microstepping performance
and sophisticated current control with anti-resonance.
Anti-resonance electronically damps motor and system
resonances, which improves motor smoothness and torque
over a wide speed range.
All setup is done via dip switches and a
rotary switch on the side of the drive,
including motor selection, running current,
idle current, and step resolution.
STR drives are available with a large family
of compatible 2-phase step motors, selected
to optimize performance of both the drive
and motor.
NOTE: These drives require step pulses from a PLC or other controller.
