Er.110: Setting Error of Frequency-Division Pulse Output

Fault Code Description:
This error occurs when using the encoder’s frequency division output function (H05-38 = 0), and the set frequency division pulse count does not match the encoder specifications.

Possible Causes and Solutions:

   The frequency division pulse count does not match the encoder specifications:
   - Troubleshooting Method: For incremental encoders, the frequency division pulse count must not exceed the encoder's resolution.
   - 20-bit serial incremental encoder resolution: 1048576 P/r.
   - 2500-PPR serial incremental encoder resolution: 10000 P/r.
   - For absolute encoders, the frequency division pulse count must not exceed one-quarter of the encoder's resolution.
   - Solution: Adjust the value of H05-17 (Encoder frequency division pulses) according to the encoder's specifications.

Important Notes:

   Incremental Encoder: The pulse count depends on the encoder’s resolution. If this resolution is exceeded, this error occurs. Ensure that settings are correct.
   Absolute Encoder: The frequency division pulses should not exceed one-quarter of the encoder's resolution. Otherwise, this error may occur.

Summary: This error indicates incorrect configuration of the encoder’s frequency division settings and can be easily resolved by following the steps above.

Er.111: Servo Internal Parameter Error
An abnormality in the internal parameters of the servo drive has been detected.

Er.120 - Product Model Mismatch Error

Fault Code Description:
Er.120 indicates a mismatch between the model numbers or power ratings of components like the motor and servo drive. This error typically occurs when the power ratings of the servo drive and motor do not match or when serial numbers are missing or incorrect.

Causes:

   Product Serial Number (SN) Missing (motor or servo drive):
   - The serial number of the servo motor or servo drive may not be set or may be incorrect.

   Motor and Servo Drive Power Ratings Do Not Match:
   - The motor's rated current may be higher than the servo drive's rated current.

   Encoder Type Does Not Meet Requirements:
   - The encoder type used may not be supported by the servo drive.

Troubleshooting and Solutions:

   Product SN is missing:
   - Troubleshooting Method: Check the labels of the servo motor and servo drive. Ensure that the equipment used is an IS620P series servo drive and a 20-bit servo motor (-U2***). Also, verify that the value of H00-00 (Motor SN) is set to 14000.
   - Solution: If the serial number of the motor or servo drive is missing, set the correct serial number (H00-00 = 14000).

   Motor and servo drive power ratings do not match:
   - Troubleshooting Method: Compare the rated current of the motor and the rated current of the servo drive. If the motor’s rated current is higher than the servo drive’s, the power ratings do not match.
   - Solution: Replace the mismatched product with one that has the correct power rating.

   Encoder type does not meet requirements:
   - Troubleshooting Method: Check whether the encoder type used is supported by the servo drive. You can verify the encoder type by checking the manual.
   - Solution: If the encoder type does not meet the requirements, use a compatible encoder or servo drive.

Summary: Er.120 error is usually caused by mismatched power ratings between the motor and servo drive, incorrect product serial numbers, or unsupported encoder types. Choosing the correct products and making the appropriate settings will resolve this error.

Er.121 - Invalid Servo ON Command (S-ON Signal Invalid)

Fault Code Description:
Er.121 indicates that the external S-ON (Servo ON) signal is active when the servo drive is internally activated. This means the external S-ON signal is either incompatible with the servo drive or has been given unnecessarily.

Causes:

   External S-ON signal active when servo drive is internally activated:
   - An unnecessary S-ON signal might have been given while using auxiliary functions.

Troubleshooting and Solutions:

   External S-ON signal active when servo drive is internally activated:
   - Troubleshooting Method: Check if auxiliary functions (H0D-02, H0D-03, H0D-12) are being used and if the DI (Digital Input) function FunIN.1: S-ON signal is turned on.
   - Solution: Turn off the FunIN.1: S-ON signal in hardware DI and virtual DI functions. This will prevent the unnecessary S-ON signal from activating.

Summary: Er.121 error occurs when an unnecessary S-ON signal is given while using auxiliary functions. To resolve this issue, check the DI function and related auxiliary functions, and turn off the S-ON signal if necessary.
