sinee — 10.2Warning diagnosis and handling measures

196 Technical Manual for EA190 Series Servo Driver V100 Warning reason Inspection Handling method Excess environment temperature Check whether the ambient temperature falls within the permitted range Improve the cooling condition of the servo driver and lower the ambient temperature The driver cooling fan is damaged Check if the cooling fan of the driver runs during operation Replace the non-operating fan Installation direction of the servo driver or the air inlet/outlet of the cooling fan is blocked 1: Check whether the driver is installed in conformity to specified requirements 2: Check whether the radiator of the driver is blocked 1:

Install the driver according to requirements provided in Chapter II 2: Clear blockage The servo driver has some fault Cut off the power and wait for some time before restart the device If the alarm still remains, replace the servo driver RLE03 : Motor overload warning Warning reason Inspection Handling method The motor load reaches the overload warning threshold set by P8-09 1: Refer to Al00D and Al00E 2: Parameter P8-09 is set too small 1: Refer to Al00D and Al00E 2: Properly increase the set value of P8-09 RLE04 : Driver overload warning Warning reason Inspection Handling method The driver load reaches the overload warning threshold set by P8-08 1: Refer to Al00D and Al00E 2:

Parameter P8-08 is set too small 1: Refer to Al00D and Al00E 2: Properly increase the set value of P8-08 RLE05 :

Position deviation too high warning Warning reason Inspection Handling method The warning threshold for a position following error is too small Check whether parameter P1-18 is set properly Increase the set value of P1-18 The pulse command frequency is higher than the requirement of the specification Check the pulse command frequency Adjust the pulse frequency to make it no higher than the requirement of the specification 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 RLE06 :

Braking overload warning Warning reason 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 braking resistor with proper resistance The load inertia is too high Check whether the total load/rotor inertia ratio is proper Reduce the load inertia or replace with a motor with higher inertia Improper parameter setting Check the settings of the braking resistor (P8-10) and the braking resistor power (P8-11) Set the P8-10 and P8-11 parameters correctly Check whether the braking resistor derating percentage (P8-13) is proper When an external braking resistor is used, if the power is high enough, increase the set value of P8-13 Check whether the deceleration time is too short Increase the deceleration time. - PoT - : Forward overrun warning Warning reason Inspection Handling method
