6. Troubleshooting
6.1 What to Do When a Problem Occurs
If a problem occurred, follow the steps below to facilitate speedy recovery and prevent the same problem
from occurring again:
a1. Check the status indicator lamps on the ACON/PCON controller.
SV (steady green) --- The servo is on.
ALM (steady red) --- An alarm is present, or an emergency stop has been actuated or the motor
drive source has been cut off.
a2. Check the status indicator lamps on the PSEL controller main unit.
PWR (steady green) The power is properly turned on.
RDY (steady green) Ready status
ALM (steady orange) Alarm status
EMG (steady red) Emergency stop status
SV1 (steady green) The servo is ON for the first axis.
SV2 (steady green) The servo is ON for the second axis.
b. Check if any alarm has been generated.
If an alarm is present, you can check the corresponding error code by connecting the PC software or
teaching pendant.
Even after the controller has been reset, detailed error information can still be checked using the PC
software or teaching pendant.
c. Check the cables for poor contact, disconnection, or pinching.
Before checking electrical continuity, turn off the power (to prevent a runaway system) and disconnect
the cables (to prevent a sneak current path).
d. Investigate the events leading up to the problem and the operating condition when the problem
occurred.
e. Check the serial numbers of the controller and actuator.
f. Check the controller firmware version.
g. Analyze the error cause.
