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.
Input terminal
Main circuit power
supply input (L1, L2,
L3)
Control Circuit Power
Supply Input Termi-
nals (24 V, or +24 V,
0V)
*1. The values outside parentheses indicate the rated value, and the values inside parentheses indicate the range
of acceptable variation. If the voltage is out of this range, operation failure may result. Be sure that the power
supply is within the specified range.
Make sure that the power supply voltage for control input signals is within the range of 12 VDC-5% to
24 VDC+5%, and the power supply voltage for safety input signals is within the range of 24 VDC±5%.
If the voltage is out of this range, operation failure may result. Be sure that the power supply is within
the specified range.
Checking the Error Occurrence
Check whether an error exists by the use of the 7-segment LED display on the front of the Servo Drive
or from the Sysmac Studio.
 When an Error Exists
Check the error display () and make an analysis based on the error that is indicated.
Refer to 12-5-1 Troubleshooting Using Error Displays on page 12-16.
 When an Error Does Not Exist
Make an analysis according to the error conditions.
Refer to 12-5-3 Troubleshooting Using the Operation State on page 12-42.
