Power-on Order
If the power to the external device is turned ON before the start of the Controller is completed, DA
output or pulse output may be output momentarily during the startup of the Controller, and the external
device may malfunction.
To avoid malfunction of the external device, configure the external circuit so that the power of the ex-
ternal device is turned ON after waiting for 2 seconds or more after the start of the Controller is com-
pleted.
A CK5M CPU Unit starts up in approximately 20 to 40 seconds and a CK3M CPU Unit starts up in 40
to 60 seconds.
The Controller startup time varies depending on the slave and unit configuration, so check with the de-
vice to be used and take sufficient margin for the waiting time for turning ON the power to the external
device.
