Troubleshooting and Error Codes 1-11
73 HiHp PrChrg Cntc Precharge Contactor Fault - the
precharge contactor did not send
back the active feedback.
On drives with DC input:
•
Check for loose or incorrect
connections from the external
precharge circuit to the X50
terminal block and to the ASIC
board (X9 and X15)
On drives with AC input:
•
Check the precharge resistors
and relays on the Rectifier board
74 HiHp PwrEE Error Power EEPROM Error - the CRC of
the data stored in the High Power
Fiber Optic Interface circuit board
EEPROM does not match the stored
CRC.
1. Cycle power.
2. Check the communication bus
lines:
•
10 pin connector between the
Main Control board and High
Power Fiber Optic Interface
board
•
Fiber-optic connections
between the High Power Fiber
Optic Interface board and ASIC
board
3. Replace the High Power Fiber
Optic Interface board
4. Replace the ASIC board
75 HiHP PwrBd
Otemp Power Board Over Temperature - the
temperature of the High Power Fiber
Optic Interface circuit board has
exceeded 85
°
C.
•
Verify that the ambient
temperature is within the
specification.
•
Check the main cooling fan and
fan power supply, replace if
necessary
•
Replace the Power modules if the
ambient temperature is within
specification and the cooling fans
are operating properly
81 + Soft Over Trvl (Motion Only)
Position feedback exceeds the
maximum positive travel setting,
parameter 694 [Motn Mx Pos Trvl].
Configured with parameter 395 [+Sft
OvrTrvlCnfg]
82 - Soft Over Trvl (Motion Only)
Position feedback, exceeds the
maximum negative travel setting,
parameter 695 [Motn Mx Neg Trvl].
Configured with parameter 396 [-Sft
OvrTrvlCnfg]
83 + Hard Over Trvl (Motion Only)
Signal for the hardware positive over
travel appears on a digital input.
Configured with parameter 397 [+Hrd
OvrTrvlCnfg]
84 - Hard Over Trvl (Motion Only)
Signal for the hardware negative over
travel appears on a digital input.
Configured with parameter 398 [-Hrd
OvrTrvlCnfg]
85 Position Error (Motion Only)
Parameter 769 [Position Error]
exceeded parameter 696 [Motn
PositErrTol].
•
Verify the value in [Motn
PositErrTol].
•
Configured with parameter 399
[Position ErrCnfg]
86 Drive Homing When the drive is in Drive Homing
mode (parameter 740 [Position
Control], bit 24 or bit 27 is On), the
Drive Homing Alarm triggers and the
drive moves to a home position
automatically.
•
Check parameter 740 [Position
Control], bit14 “Find Home” or bit
27 “Return Home”.
No. Name Description Action (if appropriate)
