A compact, powerful, digital step & direction drive available in
two power ranges: 4 A/phase and 8 A/phase. Great for OEM
applications requiring basic step & direction control of a
2-phase step motor.
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.
Features:
- Low cost, digital step motor driver in compact package
- Operates from Step & Direction signals or Step CW & Step
CCW (jumper selectable)
- Enable input
- Fault output
- Optically isolated I/O
- Digital filters prevent position error from electrical
noise on command signals
- Jumper selectable: 150 kHz or 2 MHz
- Rotary switch easily selects from many popular motors
- Electronic damping and anti-resonance
- Automatic idle current reduction to reduce heat when motor
is not moving
- Switch selectable: 50% or 90% of running current
- Switch selectable step resolution: 200 (full step), 400
(half step), 2000, 5000, 12800 or 20000 steps/rev
- Switch selectable microstep emulation provides smoother,
more reliable motion in full and half step modes
