6. Other - Operation Setting

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.
