sinee — 10.1Alarm diagnosis and handling measures

194 Technical Manual for EA190 Series Servo Driver V100 replacement of the battery through AF-16. RL01B : Driver and motor matching error Reason for alarm Inspection Handling method The driver and the motor do not match 1: Check whether the motor and the driver have consistent voltage level 2: Check whether the motor code in the driver is consistent with that on the motor nameplate 1: Correctly match the driver and the motor 2: Enter a correct motor code RL01C :

Homing failure Reason for alarm Inspection Handling method Parameter Pb-00 is set too small Check whether a proper value is set for Pb-00 Increase the value of Pb-00 The external detector or limit switch fails Check the external detector, limit switch and wire Troubleshooting RL01D : Main power failure Reason for alarm Inspection Handling method The main circuit power is cut off Check whether the power supply logic is correct Adjust the power supply logic, or maintain the current status when the main circuit power needs to be cut off RL01F :

The system needs to be restarted Reason for alarm Inspection Handling method Some operations require restart of the driver to become valid None Cut off the driver power and power it on again RL027 : UVW short-to-ground alarm Reason for alarm Inspection Handling method The motor U, V or W wire is shorted to the ground Check the motor wire and connectors. Make good of insulation Internal wire insulation of the motor is damaged Check insulation of the motor windings Send it to the distributor or manufacturer for repair RL028 :

Load inertia identification fails Reason for alarm Inspection Handling method The load inertia is too high Check whether the load inertia is too high Manage to reduce the load inertia or replace with a motor with higher inertia The mechanical connection between the load and the motor is abnormal Check whether the load and the motor is properly connected Eliminate mechanical problems The number of revolutions for the motor is too small Check whether revolutions of the motor is greater than the set value of P8-03 Properly increase the set value of the tens and hundreds places of P8-03 Properly increase the set value of P8-02 Properly decrease the set value of the thousands and hundreds places of P8-03 The set value of the tens and ones places of P8-03 is too small Check whether the motor can rotate for more revolutions RL02C :

The temperature sensor of the servo driver is abnormal Reason for alarm Inspection Handling method Open-circuit or short-circuit occurs to the built-in temperature sensor of the servo driver Check whether the alarm is cleared after power-on again Send it to the distributor or manufacturer for repair
