Troubleshooting
4-9
70
HiHp Fan Fdbk Ls
(High Horse Power Only) Fan Feedback Loss - a fan feedback signal
has been lost.
1. Check the main cooling fan.
2. Check the Main Control Board cooling fan.
71
HiHp Drv OvrLoad
(High Horse Power Only) Drive Overload - the circuit board on the
Power Module has detected an overload.
Measure output current of the drive. If the level
is ever greater than the maximum drive rated
output current level reduce the load. If the
levels are always well below the drive rated
levels, then replace the power module.
72
HiHp PwrBd PrcEr
(High Horse Power Only) Power Board Processor Error - a
microprocessor on the Power Board has detected a communication
error.
1. Check fiber-optic connections between the
Power Interface Circuit Board and Voltage
Feedback Circuit Board.
2. Check connections between the Main
Control Board and the Power Interface
Circuit Board.
3. Replace the Voltage Feedback Circuit Board
4. Replace the Power Interface Circuit Board.
5. Replace the Main Control Board.
73
HiHp PrChrg Cntc
(High Horse Power Only) Precharge Contactor Fault - proper
contactor feedback has not occurred. The precharge contactor has
probably failed to pick up or the feedback signal has failed. This fault
only applies to DC input drives.
• Check precharge circuit wiring.
• Check for loose connections on X50
terminal block and/or the X9 and X15
connectors on the ASIC Board.
74
HiHp PwrEE Error
(High Horse Power Only) Power EEPROM Error - the rating of the
drive and data in the Power EEPROM on the Power Board do not
match.
Replace output power module or program a
new power board.
75
HiHP PwrBd Otemp
(High Horse Power Only) Power Board Over-Temperature -
temperature of the Power Board on has exceeded 85
° C.
Check the main cooling fan and fan power
supply, replace if necessary.
85
Position Error
Position feedback exceeds the position error tolerance setting, Par
913 [Motn PositErrTol].
