Preliminary Checks When a Problem Occurs

This section explains the preliminary checks and analytical software required to determine the
cause of a problem if one occurs.
Checking the Power Supply Voltage
12
Check the voltage at the power supply input terminals.
Main Circuit Power Supply Input Terminals (L1, L2, L3)
R88D-KN@L-ECT-R (50 to 400 W):
R88D-KN@H-ECT-R (100 W to 1.5 kW): Single-phase 200 to 240 VAC (170 to 264 V) 50/60 Hz
R88D-KN@H-ECT-R (750 W to 1.5 kW): 3-phase 200 to 240 VAC (170 to 264 V) 50/60 Hz
R88D-KN@F-ECT-R (750 W to 5 kW):
Control Circuit Power Supply Input Terminals (L1C, L2C)
R88D-KN@L-ECT-R (50 to 400 W):
R88D-KN@H-ECT-R (100 W to 1.5 kW): Single-phase 200 to 240 VAC (170 to 264 V) 50/60 Hz
R88D-KN@F-ECT-R (750 W to 5 kW):
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
When an Error Has Not Occurred
In either case, refer to 12-4 Troubleshooting on page 12-13 for details.

(2 kW to 5 kW):
... Check the error display (@@) and make an analysis based on the error that is indicated.
... Make an analysis according to the error conditions.
