Self-test method for 102-M1A1-GEN_102-T1A1-DUM Pulse Encoder

Primary Purpose

• The 102-M1A1-GEN/102-T1A1-DUM are universal Pulse-type axis control modules
• The purpose of self-testing is as follows:
       – To confirm the normalcy of Pulse output
       – To confirm the normalcy of Encoder input
       – In field environments, to detect any discrepancies between these two values, enabling a simple self-diagnostic function
           – Confirm if it’s a module issue
           – After ruling out a module issue, determine if it’s a cable connection problem

Step-by-step hardware implementation instructions

• Hardware: 102-M1A1-GEN + 102-T1A1-DUM
       – Prepare a CN3 connector for 102-T1A1-DUM
       – Wire the C3 connector as follows:As follows
           – PB- ↔ EB- ; PB+ ↔ EB+;
           – PA- ↔ EA-; PA+ ↔ EA+

• For the CN5 part, follow the original machine’s connection method, but ensure that EMG is connected to GND

Step-by-step software implementation instructions

• Software: Use the MyLink tool and configure as follows
       – For the MIO settings, you can follow the original equipment’s connection method
           – Pay attention to the following signals, which should not be activated: EMG / EL+ / EL-
       – For Pulse I/O settings, perform the following steps twice
  A. PulseOut_Mode: 選擇CWCCW_Falling
  A-1. PulseIn_Source: Select External
  A-2 PulseIn_Mode: Select CwCCw
  A-3 Perform single-axis control and confirm that the Command / Position values are the same
  B. PulseOut_Mode: Select ABPhase_Alog
  B-1. PulseIn_Source: Select External
  B-2 PulseIn_Mode: Select 4xAB
  B-3 Perform single-axis control and confirm that the Command / Position values are the same

Conclusion

• After performing the settings twice and executing the Repeat function multiple times
       – If the values remain consistent for both runs, it indicates that the module is functioning normally, and you should check the cable connections
       – If the values are inconsistent between the two runs:
           – Please check the Pulse I/O settings
           – The module may be damaged
