6-1-1 Preliminary Checks when a Problem Occurs
This section explains the preliminary checks and analytical tools required to determine
the cause of a problem if one occurs.
Checking the Power Supply Voltage
• Check the voltage at the power supply input terminals.
Main-circuit Power Supply Input Terminals (L1, L2)
Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
If the voltage is outside of this range, there is a risk of incorrect operation, so be
sure that the power supply is correct.
• Check the voltage of the sequence input power supply and verify that the +24 VIN
Terminal (pin CN1-5) is within the allowed range of 23 to 25 VDC. If the voltage is
outside of this range, there is a risk of malfunction, so be sure that the power supply
is correct.
Checking Whether an Alarm Has Occurred
Check the alarm indicators (AL1 to AL3) on the front of the Servo Driver to see
whether an alarm has occurred.
Checking Whether an Alarm Has Occurred
• When an alarm is indicated:
Check the status of the alarm indicators (AL1 to AL3) and evaluate the problem
based on the alarm indicated.
• When an alarm is not indicated:
Evaluate the problem with the error information.
Note: In either case, refer to 6-3 Troubleshooting for details.
