31
Precharge Error
➁
The precharge function has failed to complete within 30
seconds (default) of the precharge request. The precharge time
out is configurable by
A precharge request is initiated when the DC Bus voltage is
above the Undervoltage Trip level and the precharge input is
high (the requirement for the precharge being high can be
bypassed by setting
[PreChrg Control] bit 01 “PreChrg
Enable” off).
Verify the value in
[PreChrg
TimeOut].
Verify the bit value in
[PreChrg
Control] = 1 “Enbl PrChrg”.
Configured with
[PreChrg Err Cnfg]
32
PWM Asynch
➀
The Motor Control Processor is not synchronized with
SynchLink.
33
+/- 15volt Power
➀
The12V DC control voltage is outside the tolerance range. The
positive voltage power must be within the band from +17.00 to
+11.61V DC. The negative voltage power must be within the
band from -17.00 to -11.61V DC.
Replace switch mode power supply. For
smaller frames, replace drive.
35
Parameter Chksum
➀
The checksum read from the EEPROM does not match the
checksum calculated
Cycle power
Replace Main Control Board
38
Brake OL Trip
➁
The calculated temperature of the dynamic braking resistor is
too high. The temperature is calculated by a thermal model.
If the resistor is internal, the model uses resistor characteristic
stored in the power structure EEPROM memory.
If the resistor is external, the model uses values of
[Brake Watts].
Verify actual temperature of brake:
-
If hot, wait for brake to cool
-
If cold, cycle power to the drive
If cold, verify Par 416 [Brake PulseWatts] and
Par 417 [Brake Watts] are correct.
Configured with
[Brake OL Cnfg]
39
PowerEE CRC Fail
➀
The Cycling Ring Checksum (CRC) of the data stored in the
Power Board EEPROM does not match the stored CRC.
Cycle power
In High Horse Power units, check
communication bus lines - 10 pin connector in
Main Control Board, High Horse Power
interface board, and fiber optic cable
connections.
40
SLink Mult Oflow
➁
A SynchLink Multiplier Overflow has occurred.
[SL Mult
State] displays SynchLink multiplier overflow errors.
Configured with
[SL MultErr Cnfg]
41
Ridethru Timeout
➀
The drive has been in a bus loss ridethrough condition for more
than two seconds (default). The ridethrough timeout is
configurable by
[Power Loss Time].
Verify the AC Line.
Verify the value in Par 407 [Power Loss Time].
42
DC Bus Undervolt
➁
Bus voltage has fallen below the level configured by
[Line Undervolts].
Verify the AC Line.
In frames 1-4, and 9 - 13 verify the precharge
resistor is present. (With power off, there
should be a resistance between DC+ and
BR+).
In frames 5 & 6, check the precharge board
for errors. See the precharge board LED for
fault sequence.
Configured with
[BusUndervoltCnfg]
43
VoltageFdbk Loss
➁
Loss of Motor or DC Bus Voltage Feedback has occurred
because of a communication failure between Motor Control and
Voltage Feedback board.
Check the communication line between Motor
Control (MC) and Voltage Feedback board.
Replace the Voltage Feedback board.
Configured with
[VoltFdbkLossCnfg]
44
Runtime Data Rst
➂
Runtime data (hours, energy) has been reset to zero due to a
checksum error.
45
Enable Health
➀
Safety circuit is active.
Check input signal to the Safety circuit.
46
Interp Out Synch
➁
Interpolator for position feedback lost synchronization with
Velocity Position Loop (VPL).
Configured with
[Interp Flt Cnfg]
47
MC CML Task Fail
➂
Current Minor Loop (CML) task has been delayed or run with
incorrect interval.
Cycle power.
48
No Ctrl Device
➀
The controlling device (HIM or controller) has been
disconnected while the drive was running.
No. Name
