Figure 5-30 Err59 (Back EMF auto-tuning fault)
Err59
Set motor parameters correctly.
Yes
No
Replace the motor and contact
motor manufacturer to find the
demagnetizing cause.
Yes
Contact the agent or
Inovance.
Check motor parameters in group F1 are
set correctly.
Replace with a motor of the same type to
check whether the motor is demagnetized.
Figure 5-31 Err61 (Brake pipe in braking protection state for long time)
Err61
Use a braking unit.
Yes
Increase the braking protection time and
observe whether the braking resistor overheats.
If yes, replace a large braking resistor.
Contact the agent or
Inovance.
No
Check whether bus voltage is higher
than braking voltage for long time.
Yes
Check whether the braking protection
time is too short.
Figure 5-32 Err63 (Reverse running time reached)
Err63
Increase the flow fall time.
Yes
Increase the hydraulic pressure
reference fall time
Contact the agent or
Inovance.
No
Check whether the hydraulic pressure
reference fall time is too short.
Check whether the flow fall time is too short.
Yes
Note
•
Err47 and Err48 are related to the multi-pump convergent ow solution.
•
If only one pump is controlled, disable DI5. If the multi-pump convergent ow solution is used, refer to
descriptions in Appendix C.
