Standard full hardware fault protection including overcurrent, overvoltage, undervoltage, overheating, encoder break, phase loss, etc., and can store 32 sets of position programs. Applicable scenarios

Small CNC engraving machines, food packaging machines, labeling machines, automated conveying lines, small robotic arms, textile precision auxiliary machines

Usage and Maintenance

1. The suffix 3 indicates a low-voltage model. It is prohibited to connect to a three-phase 380V power supply. Only AC 200~240V power supply is supported.

2. The entire machine comes with an MGP board and 0RS firmware. Upon arrival, it can be directly matched with the same specification motor for power-on debugging.

3. The full series of MGP firmware (0RS/01VRS) for the same power DKC02.3-012-3 can be universally rewritten and replaced.

4. For high-frequency reciprocating start-stop and large inertia load conditions, it is recommended to connect an external small-power braking resistor to extend the service life.
