WARNING
Prepare the machine for motion.
Alert everyone present.
In this section, the follower mode is scaled for engineering units. Master mode and lead scaling should be
completed before proceeding with the follower mode scaling procedure.
1. Enter RUN Mode {CP 202} = Follower.
Set the Scaled Feedback display for the disired units:
2. Enter ScFbDisp EQU {CP 250} = Ratio.
3. Enter Lg Number Units {CP 449}.
In follower setpoint mode, the setpoint expresses the ratio between the follower and lead engineering units. For
example if the lead is in centimeters, the follower is in milliliters and the setpoint is 1.25, then the follower will
produce 1.25 ml per cm. Enter the follower setpoint as the ratio of follower to lead engineering units:
4. Enter your Follower SPx {CP-201}.
Verify the Follower Mode Scaling:
5. Place the CX-1200 control into “Run” and also place the lead control into "Run"..
6. If the Scaled FB {MP-40} is not what you expect to see with the Follower SP, then recalculate your scaling terms
and return to step 2.
7. Place the CX-1200 control into “F-Stop” and the lead control into "Stop".
Procedure complete.
