Diagnosis
No fault detected
Check encoder power supply wiring and encoder current
requirement Maximum current = 200mA @ 15V, or 300mA
@ 8V and 5V
Check the excitation output wiring.
Check cable continuity
Check wiring of feedback signals is correct
Check supply voltage or excitation output level
Replace feedback device
Check the encoder signal for noise
Check encoder shielding
Check the integrity of the encoder mechanical mounting
Repeat the offset measurement test
Ensure encoder power supply is correct
Ensure baud rate is correct
Check encoder wiring
Replace feedback device
Check the encoder signal for noise
Check the encoder cable shielding
Replace encoder
Check the correct encoder type is entered into Pr 15/16/17.15
Check encoder wiring
Check supply voltage level
Replace feedback device
Change the setting of Pr 15/16/17.18 and manually enter
the number of turns (Pr 15/16/17.09) and the equivalent
number of lines per revolution (Pr 15/16/17.10)
Check motor temperature
