Features


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.

CONTROLLER SECTION
Mode Of Operation:
Step and direction, Cw/Ccw
Microstep Resolution: Switch selectable: 200, 200 smooth, 400, 400 smooth, 2000, 5000, 12800, 20000 steps/revolution
Speed Range: Depends upon selected resolution; amplifier is suitable for speeds up to 50 rps
Anti Resonance: Raises the system damping ratio; eliminates midrange instability and allows stable operation to 50 rps
Waveform: Allows for fine adjustment of phase current waveform harmonic content to reduce low-speed torque ripple in the range 0.25 to 1.5 rps
Digital Noise Filter: Step pulse input: 150 kHz or 2 MHz, jumper selectable
Self Test Switch Selectable: Rotates motor 2 revolutions in each direction
Control Inputs: Step, direction, enable, optically isolated; 4 to 30 Vdc, 5 to 15 mA.
Step Input: Min pulse width = 250 ns; max pulse frequency = 2 MHz
Fault Output: Photodarlington, 80 mA, 30 Vdc max; voltage drop = 1.2 Vdc max at 80 mA
