MOOG MSD Multi Axis Servo Drive System (DC-AC)

Connect to PC: Connect Moog DRIVE ADMINIST 5 software via USB or Ethernet interface.

Parameter configuration: Use the software wizard to set motor parameters, control modes, etc.

Start test: sequentially enable the power supply, power level, and motion control, and test the motor operation under no-load conditions.

4.2 Status and Fault Diagnosis

Equipment status display:

5.1 ": No DC link voltage, not ready.

3: The power level is ready and can be started.

5 ": The drive is ready to receive the set values.

Fault indication: Display "Er" alternately flashing fault code and location, which can be reset by 24V or confirmed by software.

4.3 Safety Torque Shutdown (STO)

The STO function is implemented through X4/22 terminals and complies with IEC/EN 61800-5-2 safety standards. For detailed instructions, please refer to the independent document (CB19388).

5、 Project Planning and System Selection

5.1 Comparison of Multi Axis System Solutions

Solution for using power supply unit:

Advantages: Supports energy feedback, power factor correction, and all axes can operate at full power simultaneously.

Disadvantages: High initial investment and large space occupation.

Power supply scheme using AC-AC servo drive:

Advantages: Low cost and compact structure.

Disadvantage: Regenerated energy can only be dissipated through braking resistors, and the total number of axles is limited.

5.2 Selection calculation steps

Calculate shaft power demand: Calculate effective torque and peak power based on load torque, speed, and motion curve.

Choose motor and encoder: Select the motor type (servo motor) and encoder (Resolve, Sin/Cos, EnDat, etc.) based on dynamic performance and accuracy requirements.

Match driver: Select the corresponding size DC-AC driver based on the rated current and peak current of the motor.

Select power supply unit: Determine the specifications of the power supply unit or AC-AC driver based on the total system power, simultaneous coefficient, and DC link capacitance.

5.3 Example of cost-benefit analysis

Taking the three-axis system as an example:

Independent AC shaft scheme: investment cost of 100%, energy consumption benchmark.

AC-AC power supply multi axis solution: investment of 108%, energy saving of 5%, investment payback period of about 6 months.

Multi axis solution for power supply unit: investment of 163%, energy saving of 10%, investment payback period of about 23 months.

6、 Technical data of liquid cooling system

Coolant requirements: It is recommended to add anti-corrosion agent to deionized water to avoid excessive chloride ions and sulfates.

Flow and pressure:

Size 3-4: Approximately 3-4 L/min, maximum pressure 2 bar.

Size 6A-7: Approximately 12-14 L/min, maximum pressure 2 bar.

Temperature monitoring: When the temperature of the radiator exceeds 65 ° C (air-cooled) or 90 ° C (liquid cooled), the equipment will be protected and shut down.
