Diagram
Default Connections
General Description
This function can be used only in NE1A-series Controllers with unit version
1.0 or later.
The Enable Switch function block monitors the status of the enable-switch
device.
The Output Enable signal is ON when the input from the monitored enable-
switch device is active. The Output Enable signal is OFF when the input is not
active or an error is detected in the function block.
In addition, if the enable-switch device is the type that outputs a grip signal
and release signal, the device’s Grip Input and Release Input signal status
can be monitored. The received Grip Input and Release Input signals do not
affect the status of the Output Enable signal.
