the Analog_Offset_error.
The Analog_Offset_setpoint axes system variable is the setpoint specified
in the analog offset function block. The Analog_Offset_error is a system
variable that contains the calculated difference between the current Flex I/
O analog input and the Analog_Offset_setpoint. These variables are in the
same units as those of the predefined Flex I/O analog input module.
Programming an Analog Offset Function
To enable an Analog Offset Function, use the following GML
Commander blocks after you have configured the Flex I/O Analog Input
Module.
Before you can activate the Analog Offset function, the feedback for the
configured axis must be turned on.
Configure Cam
Use the Configure Cam block to set up the necessary conditions for
executing a time-lock or position-lock cam, or to set up a pending
position-lock cam to blend one position-lock cam profile into another.
Typically, this block immediately precedes a Time Lock Cam block or a
Position Lock Cam block
