SD7540A Stepper Motor Driver
Description
Microstepping Stepper Motor Driver - 4.0 Arms/5.6A peak (75VDC)
The AMCI SD7540A is a powerful stepper motor driver in a low cost, compact package. Externally powered from a 24 – 75VDC power supply, this drive pack can operate up to NEMA size 34 motors.
With up to 4 Arms(5.6 A peak) of half step and microstepping capabilities, this drive pack provides higher speed and torque than any other drive in its class. Yet, it is easy to connect to any differential or transistor pulse and direction motion controller signal.
The SD7540A stepper motor driver can also be easily programmed using AMCI’s SPI interface software and CSMD-5 cable. This Windows-based software allows the programmer quick access to fine-tune the application performance.
Available Versions
SD7540A: 4 Amp rms (5.6 A peak), 24 to 75 Volt driver, Micro-step capable driver for SM23 & SM34 motors, needs external power supply

Operational Specifications
| Microstepping Stepper Motor Driver - 4.0 Arms/5.6A peak (75VDC) | |
|---|---|
| Current rating: | 4.0 Arms (average current) / 5.6A peak (peak current) NOTE: There are 2 ways to express the magnitude of current in microstepping stepper motor drivers, RMS and Peak. 1 amp RMS = 1.414 amp Peak. AMCI's SD7540A stepper motor drive is rated for 4.0 amp RMS or 5.6 amp Peak. (See the tutorial on the bottom of this page for more info) |
| Resolution: | 400, 1000, 2000, and 5000 steps per revolution |
| Maximum velocity: | motor/load dependent |
| Motor connections: | eight lead series or parallel, six lead series or center tapped, or four lead motors |
