RD-026MB 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 of max. 6A.
- 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).
