16 SP200 AC Drive Quick Start Guide
Fault Codes and Troubleshooting
• If no fault condition exists, the LED will be green.
• If a fault condition exists, the LED will be continuously red when a local keypad is
connected, or flashing red when a local keypad is not connected.
• All faults can be reset by cycling the reset control input, pressing the stop key, or
cycling power, except as noted in Corrective Action in the table below.

Fault
Description Fault Cause Corrective Action
CF 2 Control Input Illegal control input
sequence. - 3-wire: Verify Start and Jog
inputs are not both ON.
- 2-wire: Verify that only one
input (Forward, Reverse, or
Jog) is on.
FL 2 Function Loss Start attempt while
STOP (Function Loss)
input is off. Verify STOP (Function Loss)
input is ON before attempting
to start drive.
LU 3 Under Voltage 1
1 Auto Resettable
- Low input line.
- Temporary loss of
input line. Check input line to verify
voltage is within operating
specifications.
HU 4 Over Voltage 1 - High input line.
- Decel time too fast.
- Overhauling load.
- Check input line to verify
voltage is within operating
specifications.
- Increase decel time.
dO 5 Drive Overload 1 Excessive driven load. Reduce the load.
OL 5 Motor Overload 1 Excessive driven load. - Verify P-02 is set correctly.
- Reduce the load.
OH 6 Over
Temperature
1
- Operating environment
is too hot.
- Fan is blocked or not
operating.
- Excessive driven load.
- Verify the ambient
temperature is < 50 °.
- Verify clearance above/
below drive.
- Check for fan obstruction.
Replace fan if required.
- Reduce the carrier
frequency (P-64).
- Reduce the load.
OC 7 Over Current 1
(300%)
- Shaft rotation blocked.
- Excessive driven load.
- Output wiring is
incorrect or shorted.
- Check for obstructions to
shaft rotation or reduce
excessive load.
- Increase accel / decel time.
- Verify output wiring is
correct.
CL 8 Bad Keypad
Connection Bad connection from
keypad to drive. Verify keypad is properly
connected to drive.
UF 9 Negative Slope Conflicting parameter
values. Adjust values of parameters -
P-50 through P-54.
J1 10 Ground Short Phase U - Verify output wiring is correct
- Verify output phase is not
grounded.
- Verify motor is not damaged.
J2 10 Phase V
J3 10 Phase W
J4 10 Phase to Phase
Short Phase U - V - Verify output wiring is
correct.
- Verify motor is not damaged.
J5 10 Phase U - W
J6 10 Phase V - W
CH 11 Checksum Failure Parameter value out of
range.
Load default parameter values
(P-60 =1), then cycle power. If
fault persists, replace drive.
UP 12 Microprocessor
Fault Internal processor error. Cycle power. If fault persists,
replace drive.
