How to solve Error Code 33

Fault code:【33】Parallel CAN communication failureReason:1. Hardware connection issues2. Protocol configuration error3. Bus load is too high4. Power supply issues5. Environmental factorsSolution:1. Cable damage/poor contact: Check and replace the damaged cable to ensure that the plug is securely fastened and not looseAbnormal terminal resistance: Connect 120 Ω resistors at both ends of the bus to ensure that the resistance values matchElectromagnetic interference: Shielded twisted pair cables and standardized grounding are used to reduce the impact of external electromagnetic interference2. Inconsistent baud rate: Unified baud rate setting for all nodes (commonly 500k or 1M)ID filtering configuration error: Check and adjust the ID filtering logic to ensure that data is received correctly3. Too many nodes: Optimize network topology, reduce branch lines or increase buffer nodesLoad rate exceeding limit: Control the bus load rate to not exceed 70%, and upgrade the bus specifications if necessary4. Voltage instability: Install a voltage regulator module to ensure that power supply fluctuations are ≤ 10%Poor grounding: Check and optimize the common ground design to reduce potential difference interference5. Abnormal temperature/humidity: Increase environmental temperature monitoring to avoid component failure due to extreme environmentsVibration interference: Strengthen the fixed points of the line to reduce poor contact caused by vibration6. Parallel synchronization issue: Ensure that all inverters start synchronously to avoid bus conflicts caused by differences in startup sequenceRedundant design: adopting dual bus architecture or adding fiber backup channelsNote: Please do not dismantle the machine without permission, otherwise it will be out of the warranty of Ktech.
