Motor Drive - Johnson Controls FRICK QUANTUM HD Operation

ACCESSING:
DESCRIPTION: This screen is used to view and set mo-
tor related calibration values that are not shown on other
screens.
This screen should be used anytime a motor related sen-
sor is found to be out of calibration. The recommended
practice for adjusting the calibration reading is to fi rst
determine which sensor(s) need to be calibrated. Once
this is determined, you must know the actual reading that
should be showing. This can be accomplished by compar-
ing the Current Value shown, with the actual value us-
ing a separate measurement device, such as a Digital Volt
Meter, or Current Clamp, etc. Determine the difference
between what the Current Value for the sensor is, and
what the reading of the separate device shows. As an ex-
ample, assume that the Motor Amps on this screen reads
120, but a separate device shows a reading of 123. Select
either the Current Value box and enter 123 there, or enter
the difference between the Current Value and the actual
reading (3) into the Offset box. The new reading will now
be 123, and should match your separate reading.
The following fi elds are provided:

[Current Value] - This box will initially show the
actual value being read by a sensor. It is also a
setpoint box that allows the user to set the cur-
rent value that is being read by the sensor to a
different value, in the case that the calibration is
inaccurate, this new value will be added to the
actual value to update the offset (see below).
[Offset] - A value entered here will allow the
user to compensate for calibration issues with
a sensor. This value is then added to the Cur-
rent Value, to create a new Current Value (see
above).
Low - This will show the low end range that the
sensor is capable of reading.
High - This will show the high end range that the
sensor is capable of reading.
Sensor Output - This will show the current type
of sensor that is being used.
I/O Board - This will show the current I/O board
that the sensor is assigned to.
I/O Channel - This will show the current I/O
channel that the sensor is assigned to.
