GPD 503 SIMPLIFIED START-UP PROCEDURE
This procedure will quickly get you up and running by Digital Operator keypad or user supplied
remote operator control. It assumes that the GPD 503 and motor are correctly wired (see pages
1-8 thru 1-15), and start-up is to be performed without any changes to factory set constants.
Detailed information on the many other features of this drive will be found in later sections of this
manual.
INSTALLATION
1. Be certain your input voltage source, motor, and drive name plates are all marked either 230V,
460V, or 575V. Other voltages can be used, but require additional programming, see Section
2.
2. Mount drive on a vertical surface with adequate space for air circulation.
3. Remove front cover, fit conduit to bottom plate, and connect power and ground wires as
shown.
CAUTION
Be certain you connect input power to terminals L1, L2, and L3 only, or serious damage
will result. Connect motor to terminals T1, T2, and T3 only.
KEYPAD OPERATION
1. Replace cover and apply input power - keypad display shows " F00.00 "; DRIVE, FWD, and
STOP lamp S are on. Press and hold JOG key, noting direction of motor rotation. If it is
incorrect, remove power, wait for “CHARGE” light to go out, then switch wires between
terminals T1, and T2. Replace cover, and apply input power.
2. Run, Stop, and Frequency (Speed) - Here, the terms frequency and speed are used
interchangeably. A value of 60.00 (Hz) in the “ F00.00 ” display equals full speed (frequency)
for common motors. Press RUN key; RUN lamp lights, STOP lamp flashes (to indicate drive is
running at zero speed). Note flashing "0" in “
F00.00 ” display. Press “up arrow” key one time
to increase display frequency value to 10.00. Press DATA/ENTER key to enter speed data,
noting that motor shaft begins to turn. Repeat this procedure using “up arrow”, “down arrow”
and “right arrow” (RESET) keys to introduce various speeds, noting that the drive responds to
each new value only after the DATA/ENTER key is pressed. The “
F00.00 ” display indicates
the frequency command the drive is looking at, whether it is running or not.
3. Reversing - can be selected while stopped, or while running. With the drive stopped, press
FWD/REV key and note the REV lamp lights and FWD lamp goes out. If drive is running
when this key is pressed, the drive will decelerate the motor to 0 Hz, then accelerate the
motor to the same speed in the opposite direction. You can try this while running, provided
your machine can be operated in reverse direction without damage.
4. Displays - With drive stopped, each time the DISPL (display) key is pressed, a different
function appears. The first function on power up is the “ F00.00 ” display, discussed above.
Press DISPL and “ 0.00 ” appears; this is a display of output frequency (speed) and is
recognized as the only display without alpha characters. The next is “ 0.0A ”; the “A” indicates
this display is output amps. For other display information, refer to Section 3.
5. Faults - If an unacceptable operating condition such as code Ou (over voltage), Uu (under
voltage), OC (over current), etc. occurs, the drive will trip, and the motor will coast to a stop.
The appropriate fault code will be displayed. Examine fault code; consult Sections 6 & 7 for
fault correction procedure.
