DF70 R6(RS485) / C6(CAN)
MS Series Motor Drives
Introduction
● High-precision alloy resistor current sensing with low temperature drift;
supports precise current measurement at voltages up to 32V
● CAN or RS485 bus communication; supports direct control via PC, MCU, PLC,
industrial PC, Raspberry Pi, or Arduino
● High-performance 32-bit ARM Cortex-M4 core
● Real-time motor temperature monitoring
● Three-phase full-bridge driver using all N-channel MOSFETs; features low internal resistance and high current capability
● 14-bit single-turn absolute magnetic encoder; requires only one-time calibration, with zero-point retention guaranteed (18-bit encoder available upon request)
