6.1. Setting Controller Start Up Mode
Clock selection
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”)
Start up mode
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.
