Interface and communication configuration

Power terminals: L1/L2/L3 incoming lines, U/V/W motor power, External braking resistor connection terminals

Encoder port: Special aviation socket, Compatible with resolver, TTL incremental ABZ encoder

Slot: Top-mounted MGP main control card, Exports DI/DO, ±10V analog, Pulse instructions Communication

1. RS232 debugging port (activated with MGP card): IndraWorks debugging, firmware burning

2. The main body is equipped with a standard PROFIBUS-DP interface, and the S20 bus port is enhanced with lightning protection and filtering

3. Optional expansion of CANopen sub-card is available Core function

The S20 only has power hardware reinforcement, while the control logic still relies on the MGP main control card to implement.

Control mode: ±10V analog speed regulation + pulse position + PROFIBUS bus integration of three axes, supporting electronic gearing, origin return to zero, and brake sequence control.

Protection: Overcurrent / overvoltage / undervoltage / overtemperature / encoder break line / output short circuit all hardware protection. The S20 fault threshold is optimized for harmonic disturbance resistance. Applicable scenarios

High-temperature sealed cabinet printing equipment, extruder auxiliary equipment, heavy-duty winding equipment, multi-axis assembly line (the internal environment of the cabinet is high, and the grid harmonics are large, PROFIBUS control system)

Usage and Maintenance

1.7 High-voltage models are prohibited from being connected to three-phase 220V power supply. They are only allowed to be powered by industrial 380V.

2. The FW base cannot be powered on independently. It must be equipped with MGP card + matching firmware. The S20 is compatible with the standard MGP card.

3. The S20 model is preferred for replacing equipment with poor ventilation and high environmental temperature. It cannot be directly replaced with the ordinary 040 base in the high-temperature position.

4. Frequent forward and reverse rotations with large inertia loads must be equipped with large-power external braking resistors.
