8.4.1.19 0x2A: Encoder channel b cable break
8.4.1.20 0x2B: Encoder channel z cable break
8.4.1.21 0x2C: SSI error
8.4.1.22 0x30: Internal nonvolatile memory initialization error
Error Code:
0x2A
Error Name:
Encoder channel b cable break
Description:
Cable break is detected on encoder channel b
Severity of error:
Minor
Action:
• Check cable and cable connection
• Check PIN assignment
• Check encoder/SSI power supply
• Check functionality
If a SSI sensor is used, this wire is not connected to the sensor. Hence, the cable break fault on
channel b will always be active.
Error Code:
0x2B
Error Name:
Encoder channel z cable break
Description:
Cable break is detected on encoder channel z / SSI data line
Severity of error:
Minor
Action:
• Check cable and cable connection
• Check PIN assignment
• Check encoder/SSI power supply
• Check functionality
Error Code:
0x2C
Error Name:
SSI error
Description:
SSI error is detected
Severity of error:
Minor
Action:
• Check cable and cable connection
• Check PIN assignment
• Check encoder/SSI power supply
• Check sensor configuration (frequency and bit size)
Error Code:
0x30
Error Name:
Internal nonvolatile memory initialization error
Description:
An internal error during EEPROM initialization / database was detected
Severity of error:
Major
Action:
• Restart the valve
If the error still occurs after restarting the valve, send the valve back to factory for
service.
