6.10. DRIVER ERRORS
When the DRIVER detects an error, it stops and interrupts the power supply to the tread belt and
elevation motor. An error code identifying the fault condition is saved in the error history log. In
addition, it sends an error status signal to the Display Board via the serial link. Upon receiving this
error signal, the Display Board halts the exercise and shows the “THE EQUIPMENT IS
BLOCKED” message on the display.
The errors logged by the inverter can also be viewed as described in the relevant paragraph of the
Service menu.
The following table shows the correspondence between the numbers, codes and possible solution:
1/OH
OVERHEATING of the heat sinks of the
low kit driver and of the PFC.
• Check the running deck
• Check the fans
•
2/OC
OVERCURRENT, even if only temporary,
on the inverter output.
• low kit driver
• Check P409 (torque) = 100-115
3/UU
UNDERVOLTAGE condition, due to an
even temporary drop in line voltage.
• Bad power distribution line of
110/220 V AC
•
4/OU
OVERVOLTAGE
•
5/ST
SERIAL TIMEOUT, there is no signals
exchange between high kit and low kit
• Check the serial communication
6/PE
EEPROM error: is generated when there is
an error detected in the data stored on the
• low kit Driver
ELEVATION MOTOR ENCODER error.
• Check Up/Down Troubleshooting
8/EdA
BELT MOTOR ENCODER error.
• low kit Driver
• Check P409 (torque) = 100-115
9/OtM
BELT MOTOR THERMAL CUT-OUT
open.
• Check motor casing fan
• Check the running belt
10/Oli
Inverter overload caused by a DC current
exceeding, for the maximum allowed time
(I2t), the maximum permissible threshold for
the inverter.
-
11/OLm
Motor overload caused by a DC current
exceeding, for the maximum allowed time
(I2t), the maximum permissible threshold for
the motor in question.
-
12/OLr
Braking resistor overload.
• Check the resistor=150 Ω
