Motor
Graco Motors
To calibrate and autotune motors purchased from
Graco, perform the following steps:
1.
Motor Selection. Parameter Pr 20.37 is reserved
for the motor calibration information listed on the
pump’s identification plate. The value of Pr 20.37 is
determined as follows:
EP1XXX=> Pr 20.37 = 1
EP2XXX=> Pr 20.37 = 0
2.
Load Graco Motor Defaults. Navigate to Pr 20.16
and set its value to 56. At this time the specific
Graco motor parameters will be loaded and the
number 56 will be replaced by 0 automatically.
3.
Follow the instructions under Autotune the Motor,
page 10.
4.
Continue with step 1. Pressure Sensor Calibration
on page 10.

CAUTION
The system must be calibrated before start-up. Failure
to calibrate will result in malfunction, alarm trips, and
decreased safety.
CAUTION
Before installing the motor it must be calibrated and
autotuned, to prevent degraded performance or shut-
down due to unnecessary trips.
First, identify if the motor was purchased from Graco:
•
For motors supplied by Graco, see Graco
Motors, below.
•
For motors not supplied by Graco, see
Non-Graco Motors, below.
Graco does not support the use of the Graco VFD
CAM mode on motors not supplied by Graco.
Use only 1500 rpm or 1800 rpm rated motors.
