STR3 - Miniature Advanced Microstep Drive
Microstep Drive for step &
Great for OEM applications requiring basic step &
direction control of a 2-phase step motor
- Step & direction or CW/CCW pulse control
- High performance
- Mictostep emulation
- Simple setup
- Matched step motors available
Designed for OEMs
The STR3 miniature stepper drive is great for OEM applications requiring basic step & direction control of a 2-phase step motor. The drive accepts a range of supply voltages, from 12 to 48 volts DC, and is ideal for use with motor frame sizes NEMA 8 to NEMA 24. Recommended motors for use with this drive are listed below.
- Step & Direction or CW/CCW Pulse control
- Automatic idle current reduction
- Built-in self test move profile
- DIP switch setup - no software required
Compact Size for Mounting Anywhere
The STR3 is ultra-compact, meaning it can be mounted just about anywhere on the machine. Next to the motor, directly on the machine frame, tucked behind some other components, or located in a control panel with other devices, the STR3 is right at home.
- Compact size 2.38 x 1.77 x 1.10 inches
- Pluggable connectors for motor, supply voltage and I/O
Small but Powerful
The STR3 drive features advanced microstepping performance and sophisticated current control with anti-resonance. Each STR3 drive can microstep up to 20,000 steps/rev with a 1.8° step motor (1/100 step), and can even microstep the step motor when the command pulses are low resolution. This feature is called Microstep Emulation. Anti-resonance electronically damps motor and system resonances, which improves motor smoothness and torque over a wide speed range.
- Current range 0.3A to 3 A/phase
- Electronic damping (anti-resonance)
- Microstepping & Microstep Emulation
- Selectable digital input filter
