How to fix Inovance Servo Drives system parameter abnormal error E3.101?
- R
  Ryan TerryAug 20, 2025
  If your Inovance Servo Drives are showing a system parameter abnormal error E3.101, here are potential solutions: * Restore the default settings (2002-20h=1) and rewrite the parameters. This addresses issues caused by changes in the total number of parameters, parameter values exceeding limits after software updates, control power voltage drops, or power failures during parameter storage. * If parameter writing limits have been exceeded, change the parameter writing method and rewrite the parameters. If the servo drive is faulty, consider replacing it. * If the issue occurred after a software upgrade, reset the servo drive model and servo motor model, and restore the default settings (2002-20h=1). * If the servo drive is faulty, replace it.

Why Inovance SV820N display product model matching fault E3.120?
- M
  Matthew FrancisAug 23, 2025
  The E3.120 error on Inovance Servo Drives indicates a product model matching fault. This can occur due to several reasons: * The motor model and drive model do not match, the parameter setting is incorrect, or the inverter module recognition is incorrect. To resolve this, set 2000-01h (Motor SN) correctly according to the motor nameplate or use a matching motor. * The power rating of the servo motor does not match that of the servo drive. Replace the mismatched products, referring to the '1.4 Table of Servo System Configuration Specifications'. * Settings of the inverter model do not match auto-recognition results. To fix this, set 2001-10h the same as 2001-62h or replace the inverter module.

What to do for Inovance Servo Drives motor overload error E3.620?
- J
  Jennifer KennedyAug 26, 2025
  When Inovance Servo Drives show a motor overload error E3.620, it means the motor's heat accumulation has reached a critical level. To address this: * Use a servo drive of larger capacity and a matching servo motor. * Reduce the load on the motor. * Increase the acceleration/deceleration time to reduce stress on the motor.

  sandra30Aug 28, 2025
  If your Inovance Servo Drives are displaying an internal program abnormal error E3.105, consider the following steps: * Restore the default setting (2002-20h=1), and power on the system again. This can resolve issues related to an abnormal number of parameters during EEPROM read/write operations, abnormal parameter data ranges (often after software updates), or an EEPROM fault. * If the servo drive is faulty, replace it.

What does error E3.130 mean on Inovance Servo Drives?
- D
  Dale CamposSep 4, 2025
  Error E3.130 on Inovance Servo Drives means that different DIs (Digital Inputs) have been assigned the same function. To resolve this, allocate parameters that have been allocated with the same non-zero DI function No. with different DI functions. Then, turn the control power off and on again to allow the modifications to take effect.

What to do if Inovance SV820N Servo Drives show invalid S-ON command error E3.121?
- M
  mgraySep 7, 2025
  If your Inovance Servo Drives are showing an E3.121 error, this indicates an invalid S-ON command. This typically happens when a redundant S-ON signal is given while using certain auxiliary functions. The solution is to turn off the S-ON signal from the host controller.

What causes abnormal communication initialization of coprocessor E3.102 in Inovance SV820N Servo Drives?
- B
  brianmeyersSep 9, 2025
  Abnormal communication initialization of the coprocessor, indicated by error E3.102 in Inovance Servo Drives, can be due to a multi-core communication initialization fault, mismatched software versions between cores, or a faulty FPGA. Contact Inovance for technical support and update the software to ensure compatibility. If the FPGA is faulty, replace the servo drive.

What does Inovance Servo Drives error E3.104 mean?
- K
  karen44Sep 12, 2025
  Error E3.104 on Inovance Servo Drives indicates abnormal communication or interrupt timeout of the coprocessor. This is due to coprocessor or FPGA interrupt timeouts, or cyclic access timeouts among coprocessors. The solution is to replace the servo drive.
