Interface and communication configuration

Power terminals: L1/L2/L3 three-phase incoming lines, U/V/W motor power terminals, dedicated terminals for external braking resistors

Encoder aviation socket: Compatible with rotary transformers, TTL incremental ABZ, full type feedback of sine encoder

Top card slot: Fixed assembly of MGP-7 high-voltage main control card, card body outputs DI/DO switch quantities, ±10V analog speed regulation, pulse direction instructions

Communication interfaces

1. RS232 debugging serial port (enable MGP card): IndraWorks parameter debugging, firmware download and burning

2. Integrated native PROFIBUS-DP bus interface in the body, 03.3 model type标配 DP， does not support SERCOS bus

3. Card slot can be expanded to select CANopen sub-card Core function

The main body only consists of power inverter hardware, and all motion control functions are realized by the MGP-7 control card.

Control mode: ±10V analog quantity, pulse position, PROFIBUS bus multi-axis control combined in one, supporting electronic gearing, master-slave synchronization, origin search, and motor brake timing control.

Hardware full protection: overcurrent, overvoltage, undervoltage, power module overheating, encoder break, output phase-to-phase short circuit, bus fault self-lock shutdown. Applicable scenarios

Heavy-duty CNC floor-mounted lathes, rubber-plastic single/double screw extrusion main machines, large-scale cable winding units, heavy-duty paper coating roller systems, automated heavy-duty handling truss equipment.

Usage and Maintenance

1. -7 The high-pressure base must not be connected to AC220V three-phase power supply. It is only allowed to use 380~480V industrial power supply. Misconnection will directly damage the power module.

2. The FW empty base cannot be powered on and operated independently. It must be equipped with the corresponding MGP-7 main control card + matching power firmware.

3. Frequent start-stop and large inertia impact loads must be equipped with external high-power braking resistors to prevent the internal braking circuit from breaking down.

4. The 100A/40A small-power base cannot be directly replaced. The bus capacity and power IGBT hardware specifications are not compatible.
