Product Features

RD-024MB is a 2-phase Stepping Motor Driver that enables the micro-stepping drive. Positioning control by the pulse string signals from Generate Master RC-234 is available.

• Max. 50 V DC supply enables high speed operation.
• New circuit method largely reduces heat generation more than existing products in spite of being high output.
• Low vibration using high resolution micro-stepping.
• All signal input/output circuits are insulated using photo-couplers.
• Switching between 2-clock method and one clock method is available.
• Automatic current down (adjustable current value).
