With the default settings at shipping, a parameter is set to start up the controller in RS-232C 

communication command input mode (internal clock). When assembling the device, however, the 

mode can be switched for start up with an external clock (high-speed serial communication). For this 

switching, the following parameter is set: 

 

Parameter ID 

Data 

64 

Bit 1      0: RS-232C communication command input   
       1: High-speed serial communication 

 

              P64 = 1: Start up with internal clock 

              P64 = 3: Start up by high-speed serial communication 

 

(Bit 0 of P64 is used to enable or disable encoder correction when homing to the origin; it is usually set 

to 1. For details, see 9.2. , “Parameter Details”) 

 

Power-on usually executes the following automatically: 

・

Reading parameters from EEPROM 

・

Starting homing and servo control 

If there is a problem with the parameters read from EEPROM or if oscillation occurs when homing and 

servo control are executed automatically, the start up mode can be changed. 

 

For this switching, the switches (SW1 and SW2) on the controller board and the logic of the digital I/O 

terminal (A6) are combined.
