12-1-1 Preliminary Checks When a Problem Occurs

This section explains the preliminary checks 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, L3)
R88D-KN L-ECT
R88D-KN H-ECT
R88D-KN F-ECT
Control Circuit Power Supply Input Terminals (L1C, L2C)
R88D-KN L-ECT
R88D-KN H-ECT
R88D-KN F-ECT
If the voltage is out of range, there is a risk of operation failure. Be sure that the power supply is
within the specified range.
• Check the voltage of the sequence input power supply (+24 VIN terminal (CN1 pin 7)).
It must be between 11 and 25 VDC.
If the voltage is out of range, there is a risk of operation failure. Be sure that the power supply is within
the specified range.
Checking Whether an Error Has Occurred
• Make an analysis using the 7-segment display on the front of the Servo Drive or using CX-Drive tools.
• When an Error Has Occurred
... Check the error display (
• When an Error Has Not Occurred
... Make an analysis according to the error conditions.
• In either case, refer to 12-4 Troubleshooting on page 12-14 for details.
