See RL002 for details 191 Technical Manual for EA190 Series Servo Driver V100 driver Encoder wiring error Check is the encoder is wired following the recommended route in the instructions Correct wiring Poor encoder wiring Check whether the CN5 and encoder of the driver are properly connected and if the shielding layer is sound Reconnect the wire The encoder is damaged After the wiring problem is eliminated, this alarm still occurs Replace the motor RL008 : Encoder abnormality 2 Reason for alarm Inspection Handling method Abnormal AB signal of an incremental encoder CRC check error of an absolute type encoder Same as Al007 Same as Al007 RL009 :
Encoder abnormality 3 Reason for alarm Inspection Handling method Abnormal Z signal of an incremental encoder Same as Al007 Same as Al007 Communication error of an absolute type encoder RL00R : Undervoltage Reason for alarm Inspection Handling method Input voltage of the main circuit is lower than the permitted value Check whether the input voltage and wiring of the main circuit are normal Recheck the power wiring No input voltage of the main circuit Check whether the main circuit voltage is normal Recheck the power switch Power error Check whether the power is consistent with the specification Use a proper power source RL00B :
Overvoltage Reason for alarm Inspection Handling method Input voltage of the main circuit exceeds the permitted value Check whether the main circuit voltage falls within the permitted range Use a proper power source Power input error Check whether the power is consistent with the specification Use a proper power source Too fast deceleration of the motor Check if the system inertia is too high and if the deceleration is too fast Prolong the deceleration time, or use an appropriate external braking resistor The load inertia is high and no braking resistor is connected Check whether overvoltage occurs upon stop Install a braking resistor with proper capacity and resistance, and correctly set the braking resistor parameter Driver hardware alarm The main circuit voltage is within the permitted range according to measurement, but this alarm still occurs when the motor is not running Send it to the distributor or manufacturer for repair RL00C :
Software over-current RL00D / RL00E : Motor overload/driver overload Reason for alarm Inspection Handling method Continuing use when the rated load is exceeded 1: Monitor whether d0-01 is constantly above 100% 2: Monitor whether d0-46 is constantly above the rated value 3: Monitor whether d0-47~49 1: Increase the motor capacity or reduce the load 2: Increase the driver capacity or reduce the load
