DCM-2 HART INTERFACE Calibration - Feedback
FEEDBACK SIGNAL
CALIBRATION
DCM-2 boards have the capability of providing
a 4–20 mA output signal so that the drive’s true
output shaft travel can be monitored remotely.
The signal comes calibrated from the factory to
provide a precise 4–20 mA signal corresponding
to 0–100% drive travel. Normally, calibration
is not required even if the position reference
calibration or direction of travel are changed,
because the DCM-2 automatically compensates
for these changes and appropriately scales the
position feedback signal.
If the Feedback must be changed, it is
accomplished by using a Hart communication
device. First, navigate to the Configuration menu.
Next, select the Feedback Setup submenu.
Through this submenu, the Feedback range may
be changed, as well as the curve. Online help is
available through the communication device.
