193 Technical Manual for EA190 Series Servo Driver V100 The gain setting is too small Check if the setting is appropriate Properly set the gain value The torque limit is too low Check the torque limit value Properly adjust the torque limit value The load inertia is too high Calculate the ratio of the load to the rotor inertia of the motor Reduce the load inertia or reevaluate the motor capacity RL014 :
Input phase loss Reason for alarm Inspection Handling method Main circuit power abnormal Check whether power lines L1, L2 and L3 are loose or there is only single-phase input Make sure a normal three-phase power source is connected; if the abnormality persists, send the product to the distributor or manufacturer for repair Drive parameter setting error Set the single-phase power supply to three-phase power supply for the driver Set the parameter correctly RL015 :
Motor phase sequence error Reason for alarm Inspection Handling method The motor rotates in a direction inconsistent with the set direction Check whether U, V and W are properly wired Ensure proper wiring; if the abnormality persists, send the product to the distributor or manufacturer for repair RL016 : Parameter setting abnormal Reason for alarm Inspection Handling method Some parameters of the driver are abnormal - Check d2-09~d2-10 and the driver nameplate and make records; contact the distributor or manufacturer RL017 : Braking resistor overload Reason for alarm Inspection Handling method No braking resistor is connected or the braking resistor connected has a too small capacity 1:
Check connection of the braking resistor 2: Calculate resistance of the braking resistor 1: Reconnect the external braking resistor 2: Use a suitable braking resistor IGBT for braking fails Check whether the IGBT for braking is damaged Send it to the distributor or manufacturer for repair The parameter is set incorrectly when an external braking resistor is connected Check the settings of the braking resistor (P8-10) and the braking resistor power (P8-11) Set the parameter correctly RL018 :
Encoder overheated Reason for alarm Inspection Handling method The absolute type encoder is overheated Check whether the ambient temperature for motor operation is too high Lower the ambient temperature or cool down the motor by forced air cooling RL019 : Battery low alarm for the absolute type encoder Reason for alarm Inspection Handling method The battery voltage of the absolute type encoder is lower than 3.1V Measure the battery voltage Replace the battery (make sure the encoder and driver CN5 terminals are well connected and the battery is replaced when the driver is powered on.
If the battery is replaced when the encoder is powered off, an Al01A alarm will occur upon power-on again) RL01R : The battery voltage of the absolute type encoder is too low Reason for alarm Inspection Handling method The battery voltage of the absolute type encoder is lower than 2.5V Multi-turn position information is lost Measure the battery voltage Replace the battery, manually clear the multi-turn alarm information through AF-16 after power-on, power the encoder on again Fail to clear alarms after Clear the multi-turn alarm information
