7.3 Fault Codes
When there is a fault, you can view the fault code using the value in parameter 10
[
LAST FAULT], the value of Class 0x29 (Control Supervisor Object), Instance 1,
Attribute 13 (Fault Code), or the display on the keypad.
Fault Codes
1
Name Description Corrective Action
Parameter
Value DeviceNet Display
0 0x0000 No Fault Normal operation. No action required.
1 0x5300 F.FL Function Loss Open connection on
Function Loss control
terminal block inputs
(terminals 7 and 11).
- Check and restore the Function Loss
connection on the terminal block. Refer to
VSM500 Integrated Drive/Motor User
Manual .
- Check the external sensors wired into the
Function Loss string.
2 0x2220 F.OC Over Current Shaft rotation blocked.
Excessive driven load.
Input power is not
correctly wired to the
VSM500 unit.
Motor section ground
fault.
- Check for obstructions to shaft rotation.
- Reduce excessive load.
- Increase accel/decel time using the rotary
switches or parameter 32 [ACCEL TIME]
and parameter 33 - [DECEL TIMe].
- Verify that input wiring is correctly
connected. Refer to the VSM500
Integrated Drive/Motor User Manual.
- Check motor section for ground fault.
Replace VSM500 unit if a ground fault is
detected.
3 0x7122 F.OL Motor Overload Excessive current to
motor for an extended
time due to excessive
load or short circuit.
- Check for obstruction to shaft rotation.
- Reduce the driven load.
- Check input wiring is correctly connected.
Refer to the VSM500 Integrated
Drive/Motor User Manual.
- Check for blower obstruction.
- Replace blower if required.
4 0x3210 F.HU Over Voltage High input line.
Deceleration time is too
fast or overhauling load.
- Check input line to verify that voltage is
within operating specification.
- Increase deceleration time using the
accel/decel rotary switch. Refer to the
VSM500 Integrated Drive/Motor User
Manual.
5 0x3220 F.LU Under Voltage
while Stopped
Low input line or
temporary loss of input
line.
Check input line to verify voltage is within
operating specifications.
60x4310F.OHOver
Temperature
Operating environment is
too hot.
Blower is blocked or not
operating.
Excessive driven load.
- Check the application site and verify the
ambient temperature is within the
operating specification.
- Check for blower obstruction. Replace
blower if required.
- Reduce load or make sure VSM500 unit
matches the application requirement.
7 0x7510 F.CL Communication
Loss
Communication between
the DeviceNet option
board and the drive has
failed.
Check cable connection between the
regulator board and DeviceNet option
board.
80x6310F.dCHParameter
Checksum
Contents of the EEPROM
is corrupted.
Reset parameters to default values and
cycle power.
