6.1. Setting Controller Activation Mode
Clock selection
With the default settings at shipping, a parameter is set to activate the controller with the internal clock.
When assembling the device, however, the mode can be switched for activation with an external clock
(high-speed serial communication). For this switching, the following parameter is set:
Parameter ID Data
64
Bit 1 0: Internal clock
1: High-speed serial communication
P64 = 1: Activation with internal clock
P64 = 3: Activation 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 8-2, “Parameter Details.”)
Activation 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 power-on activation 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.
