BECKHOFF AMP8000 Servo Drive Installation and Debugging Manual

3.2 Power Wiring (AMP8620 X01 B23 Interface)

Single phase or three-phase power supply is connected to terminals 6 (L1), 7 (L2), 8 (L3/N), and PE is connected to terminal 5.

External fuse: maximum 25A, CE suitable for gG (A) type fuses or C-characteristic circuit breakers; UL applies Class J fuses (circuit breakers are not allowed).

Leakage current usually exceeds 30mA, and full current sensitive RCD (rated residual current ≤ 300mA) must be used. Ordinary A-type or AC type RCD cannot reliably detect high-frequency leakage current.

3.3 System output wiring (B23 interface, 9-pin)

Needle 1: TX+/GNDs (communication)

Needle 2: RX+/GNDp

Pin 3: RX -/Up (24V)

Needle 4: TX -/Us

Needle 5: PE

Needle 6:24V DC

Pin 7: DC Link Negative

Needle 8: DC Link positive

Pin 9: GND 24V

This interface simultaneously transmits EtherCAT communication, 24V control, and DC Link power, achieving single cable connection.

3.4 EtherCAT P interface (M8, P encoding)

Cascading or connecting other EtherCAT P devices for power modules/distribution modules:

Needle 1: TX+/GNDs

Needle 2: RX+/GNDp

Needle 3: RX -/Up

Needle 4: TX -/Us

Maximum cable length:

Between power/distribution modules: 75m

Between module and motor: 30m

3.5 Keep the brake manually released (only for models with M8 interface)

In service mode, 24V can be directly applied to the brake M8 interface (pin 2 positive, pin 4 negative) through a dedicated service cable (ZK2020-3100-9001) to achieve manual release. After the service is completed, the service cable must be unplugged and an M8 jumper cap and anti tamper protection must be installed, otherwise the brake cannot be maintained properly during operation.

TwinCAT Debugging Process

4.1 Online Configuration (Recommended)

Create TwinCAT project and scan I/O devices (TE5950 TC3 Drive Manager 2 needs to be installed first).

After scanning AMP8620, the system automatically identifies its submodules (power outputs X40~X41, X42~X44).

Add TC3 Drive Manager 2 project and configure power module parameters (such as brake resistor type) in "Search drives".

Scan the electronic nameplate of the motor (Select Scan motor in PreOp), and the system automatically reads the motor parameters and applies them. After successful scanning, the motor displays green.

Complete the basic NC scaling settings (load inertia, speed/torque limit) and activate the configuration.

4.2 Offline Configuration

If hardware connection is not possible, AMP8620 can be manually added (note EtherCAT P interface type, if not available, uncheck the 'Check Connector' checkbox). The motor parameters need to be input manually and can be adjusted later in the project.

4.3 Security Configuration (TwinSAFE)

The AMP8000 motor integrates safety functions, and the STO/SS1 version (model xx1x/xx2x) and Safe Motion version (xx3x/xx4x) require safety configuration through the AMP8911 TwinSAFE card. When debugging and replacing equipment, it is necessary to follow the AMP8911 operation manual, and safety configurations are not elaborated in this article.

Maintenance and Fault Prevention

5.1 Capacitor shaping (after long-term storage)

If the power module or coupling module is stored for more than 5 years, the DC Link capacitor will lose its shape, and direct power on may result in limited functionality or even shortened lifespan. At this point, the system needs to be connected to the main power supply and run without load for 60 minutes. It can only be used normally after the capacitor is reshaped.

5.2 Brake Function Inspection

Keep the brake in a normally closed state (power-off braking) for static holding and cannot be used as a safety brake (unable to monitor wear). Redundant braking or mechanical counterweights must be added in vertical axis applications. The limit of emergency stop times is: up to 2000 emergency braking times at a maximum of 3000rpm (based on the inertia of the motor itself, an increase in load inertia will reduce the allowed number of times). Functional checks can be performed using a torque wrench or TwinCAT Scope.

5.3 Cleaning and Inspection

Wipe the outer shell with dissolved grease such as isopropanol and non corrosive cleaning agents, and do not immerse or spray.

Regularly check cable wear, flange heat conduction (affecting heat dissipation), and shaft seal status.

Poor thermal connection of motor flanges can cause overheating and affect their lifespan.

5.4 Storage and Transportation

Environmental temperature: storage -25~+55 ° C, transportation -25~+70 ° C, temperature variation ≤ 20K/h.

Relative humidity ≤ 95%, no condensation.

The maximum stacking height varies by model (see documentation), and AMP8620 can stack up to 8 layers.

Common Problems and Troubleshooting Strategies

Troubleshooting steps for possible causes of fault phenomena

The LED of the power module is not lit, and the main power supply is not connected or the fuse is blown. Check the X01 voltage and measure whether the DC Link is established; Check the external fuse

Motor cannot be released (RUN light abnormal), brake not powered or M8 jumper cap missing. Check the 24V control power supply; Confirm that the M8 jumper cap has been installed and tightened (0.4Nm)
