Error Code & Diagnostics – Endurance Console:
Note: A logs of recent error codes are found in the Engineering Mode
.
1.) ER01 – Communication Error
 Communication disruption between the inverter and the upper control board :
 The inverter sends a signal to the upper control board every 1.5 seconds to check to see
if they are still in communication with each other. If no response, the inverter shuts the
AC motor down.
 The code CE10 appears on the display after the communication is reestablished

The potential reasons for the communication disruption could be :

A faulty display board
 A faulty inverter
 Faulty cabling
2) ER02 – Incline Motor Error

Loss of elevation calibration from the elevation motor to the upper display board. Or no
movement from elevation motor.
 Check for loose wires or connections. Run the Auto Calibration process to re-calibrate
the elevation pot.
 If no movement from elevation motor, check wires and connections from elevation
motor to inverter board. If elevation wire is damaged, replace Elevation Motor.

Check harness wires from Inverter Board to Upper Board, if loose or damaged wire
found, replace the Upper Harness.
3) ER03 – Safety Key/Replace Safety Key

The Upper display board monitors the safety circuit and flags this condition when the
safety is pulled. Always check that the safety key is pushed in before proceeding.
 Potential reasons for this error are:
Faulty Safety circuit
Faulty cabling
Faulty Display Board
4) ER04 – (Also OL) AC Motor Over-Current Error
 The inverter monitors the AC motor in order to determine the amount of over current.
 It also monitors the amount of time that the current is over the maximum limit. The
standard maximum limit is 150% of the rated current of the motor (which for the drive
motor the rating is 7amps). For the error code
(OL) to come up, the motor would have
to be over loaded for over 60 seconds. The inverter would then shut down the AC
drive motor.
 The potential reasons for an AC motor over-current condition could be :

Failure of one or more of the internal motor components (bearings, rotor, stator
windings, etc.)
 Excessive load on the AC drive motor putting excessive loading onto the motor (Friction
in the belt and deck, bad roller bearing, etc.)

Note- a Heavy Person walking at slow speeds may cause this error due to the extra load.
The same is true for a heavy person who is running at high speeds.
