Code
6.00V Flash Power Supply reference voltage is out of range (2411 - 2532)
2907
See self-test Voltage Reference "Max"
This tests the voltage across a sense resistor in series of the 6.00 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
8.00V Flash Power Supply reference voltage is out of range (3251 – 3417)
2908
(TR only) See self-test Voltage Reference "HTTR"
This tests the voltage across a sense resistor in series of the 8.00 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
VRef instability
2911 – 2918
This error indicates that one of the channels (voltage reference) feeding the A/D converter is
unstable, i.e., A/D max – A/D min > 8 after 8 attempts. See the table below for more information
for each channel.
Note:
the A/D converter is unstable.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
Description and Probable Causes:
If multiple channels are intermittently failing a 291x (x = channels) error, it is possible that
