DG80 R7 (RS485) C7 (CAN)
MG Series Motor Drives
Introduction
● High-precision, low-drift gold-resistor current sensing; supports precise current measurement at voltages up to 60V
● CAN or RS485 bus communication; supports direct control via PC, MCU, PLC, industrial PC, Raspberry Pi, or Arduino
● High-performance ARM main controller featuring a 32-bit Cortex-M4 core clocked at 180MHz
● Real-time motor temperature monitoring
● Three-phase full-bridge driver using all N-channel MOSFETs; features low internal resistance and high current capability
● 18-bit single-turn absolute magnetic encoder; requires only one-time calibration, with zero-point retention guaranteed
