Usage and Maintenance

1. Models with suffix 1.7 are prohibited from being connected to a three-phase AC220V power grid. Only AC380~480V power supply is allowed. Incorrect connection will directly damage the IGBT power device;

2. The bare base of FW cannot be powered on independently. It must be matched with the MGP-7 main control card of the same power segment + corresponding power firmware to be debugged and operated;

3. For high-frequency start-stop of large inertia loads, an external large-power braking resistor must be installed to prevent the built-in braking circuit from overheating and burning out;

4. DKC06 (DeviceNet), DKC05 (CANopen), and DKC04 (PROFIBUS) have similar installation dimensions, but the bus hardware is incompatible. It is not possible to directly replace spare parts across model numbers.
