Chapter 6: Fieldbus Expansion and Fast Debugging

6.1 Expansion Card Installation and Identification

AX2000 offers a variety of fieldbus expansion card options, all of which are plug and play. After insertion, the driver software automatically recognizes and activates the corresponding parameter interface:

PROFIBUS DP: Dual SubD 9 interfaces (parallel), supporting DP-V0/V1.

SERCOS: Fiber optic interface (F-SMA), supports 2/4/8/16 MBaud, requires configuration of station address (0-63) and fiber power (SLEN parameters).

DeviceNet: Rotary switch sets station address (0-63) and baud rate (125/250/500 kbps), supports Group 2 or UCMM connections.

EtherCAT: Dual RJ45 interface (IN/OUT), supporting CoE (CANopen over EtherCAT) protocol.

-2CAN -: Separate RS232 and CAN interfaces into independent SubD connectors, with built-in 120 Ω bus terminal resistance switches.

6.2 Quick Debugging Process (Quickstart)

Minimum wiring: Connect the main power supply (L1/L2/L3), 24V auxiliary power supply (X4), motor power line (X9), and feedback line (X1/X2), and connect the PC to X6 through an empty modem cable.

Start software DRIVE. EXE: Select the corresponding COM port and upload the current parameters of the driver.

Basic settings: Set the grid voltage (max. Mains Voltage), phase loss response mode (Warning/Error), and unit system.

Motor selection: Select the corresponding Beckhoff motor model from the built-in motor parameter library. If using a third-party motor, manually input the number of poles, rated current, and inductance parameters.

Feedback configuration: Select FBTYPE and verify phase angle (MPHASE) - For SinCos encoders without data channels, Wake&Shake initialization needs to be performed.

Save and Cold Start: After making critical configuration changes, it is necessary to save them to EEPROM and perform a Cold Start.

Trial operation: Verify the correctness of motor operation direction and feedback through software enable (SW Enable) and Jog function (F6 speed mode).

Chapter 7: Quick Check of Fault Codes and Troubleshooting of Common Problems

Fault code, fault description, most common causes, troubleshooting measures

F02 DC bus overvoltage regeneration energy feedback overload/external braking resistor not connected correctly. 1. Check if the X8 terminal short-circuit is removed (if an external resistor is used).

2. Measure whether the external resistance value is ≥ 33 Ω (minimum allowable value).

3. Confirm that the regeneration power parameter settings match the actual situation.

F05 DC bus undervoltage main power supply phase loss/low voltage/fuse failure 1. Measure L1/L2/L3 three-phase voltage.

2. Check the external fuse (gG type, see p.19).

F04 feedback: broken/short circuited encoder cable, broken shielding layer, loose connector. 1. Check the locking status of X1/X2 connectors.

2. Use an oscilloscope to check if the SinCos signal is normal (1Vpp).

F11 brake fault: Short circuit/disconnection of brake coil/overload of braking current. 1. Measure the resistance between B+/B - (normal value>20 Ω).

2. Confirm that the braking current does not exceed the upper limit of 2A.

N05 power phase loss warning: If one phase of the main power supply is missing (PMODE=Warning) during single-phase power supply testing, this warning is normal; If it occurs during three-phase operation, the input power supply and fuses need to be checked.

F16/F19 power supply BTB fault/phase loss error. The main power supply is severely unbalanced or lacks phase. Check the quality of the main power supply and the configuration of the upstream filtering/isolation transformer.
