EA180 Series Servo Drive Users Manual 102 Torque limit is too low Confirm the torque limit Correctly adjust the torque limit value Excessive load inertia Calculate the ratio of load inertia to motor rotor inertia Reduce load inertia or reevaluate motor capacity Al014 : Input phase loss Alarm Scenarios Inspection Troubleshooting Main circuit power supply is abnormal Check L1, L2, L3 power cords for loose connection or single-phase input only If three-phase power supply is connected correctly but there is still fault, send the device to the distributor or the manufacturer for overhaul.
Drive parameters setting error Set the single-phase powered drive to three-phase powered Set parameters correctly Al015: Motor phase sequence error Alarm Scenarios Inspection Troubleshooting The rotation direction of the motor is not consistent with the given direction. Check whether U, V, W wiring is correct If the wiring is correct but there is still fault, send the device to the distributor or the manufacturer for overhaul. Al016 : Drive exception Alarm Scenarios Inspection Troubleshooting Drive parameters setting exception - Check d2-09 ~ d2-10 and drive nameplate and make a record, then contact the distributor or manufacturer Al017 :
Braking resistor overload Alarm Scenarios Inspection Troubleshooting Braking resistor is not connected or capacity is too small. 1: Confirm the connection status of the braking resistor 2: Calculate braking resistance value 1: Reconnect the braking resistor 2: Use an appropriate brake resistor Failure of IGBT for braking Check for damage of IGBT for braking Send it to distributor or manufacturer for overhaul. Parameter setting error when an external braking resistor is connected Confirm the setting values of the braking resistance (P8-10) and braking resistor power (P8-11) parameters Set parameters correctly Al018:
Encoder overheating Alarm Scenarios Inspection Troubleshooting Absolute encoder overheating Check whether the ambient temperature of the motor is too high Reduce ambient temperature or force air cooling of motor Al019 : Absolute encoder battery low warning Alarm Scenarios Inspection Troubleshooting Absolute encoder battery voltage is below 3.1 V Measure the battery voltage Replace the battery (Please replace the battery while keeping the encoder well connected to the CN5 terminal and the drive is powered on. If the battery is replaced when the encoder is off, the Al01A alarm will occur when the encoder is powered on again.) Al01A :
Absolute encoder battery low Alarm Scenarios Inspection Troubleshooting Absolute encoder battery voltage is lower than 2.5 V, multi-turn position information has been lost. Measure the battery voltage Replace the battery and manually clear the multi-turn fault information through AF-16 function after power-on, and then power-on again.
