7. Troubleshooting
7.1 Handling Problems
If problems occur, handle them according to the following procedure for prompt recovery and prevention of
recurrence.
a. Check the status indicator LEDs
RDY (Green) Indicates that P-Driver is operating normally.
RUN (Green) Indicates that the servo is on.
ALM (Red) Indicates that an alarm is generated.
ENC (Yellow) Indicates that the encoder is disconnected or not connected.
b. Host controller errors
c. Check the voltage of the main power supply
d. Check the voltage of the power supply for I/O signal interface
e. Check the voltage of the brake power supply (in the case of an actuator with brake)
f. Check the alarm status
Check alarm codes with the PC software.
g. Check the cable connections to see if they are not disconnected or caught
When checking cables for conductivity, turn the power supply off first (to prevent runaway) and
remove wiring (to prevent current from being conducted from electrical circuits).
h. Check the I/O signals
i. Check the noise prevention measures (e.g. connection of grounding wire, installation of surge
killers)
j. Review the situation before the problem occurred and the operating conditions at the occurrence
k. Analyze the causes of the problem
l. Take appropriate action
Please check items (a) through (j) before contacting IAI.
7.2 Fault Diagnosis
Fault conditions can be classified into the following three types:
a. Errors occurring when turning the power supply on
b. Errors without alarm display
c. Errors with alarm display
