Product Display
- Isolated CANopen communication
- Built-in isolated power supply
- Low power consumption multi-turn absolute value built-in battery
- Automatic charging
- When the motor is powered, there is a charging circuit inside to charge the battery
- After the motor is not powered, the motor shaft is driven to rotate to wake up the encoder and continue to memorize the position the battery current consumption is only 0.07mA
- Battery power down alarm
- CANOPEN host computer is provided to monitor motor status and modify parameters.
- Position mode, support pulse + direction signal, encoder follow
- Speed mode, support PWM duty ratio signal speed regulation
- With locked-rotor, overcurrent protection, overvoltage protection.
