WARNING
Do not touch circuit components until main input power has been turned
OFF. Status indicator LEDs and Digital Operator display will be extinguished
when the DC bus voltage is below 50 VDC. Wait at least one additional
minute.
Do not connect or disconnect wires and connectors while the main input
power is turned on.
CAUTION
The GPD 315 leaves the factory with parameters initialized for 2-Wire control
(when using external Run/Stop signals). Before using the initialization
function of constant
n001 , know your control wiring configuration:
8 = Factory 2-Wire Control Initialization (Maintained RUN Contact)
9 = Factory 3-Wire Control Initialization (Momentary START/STOP Contact)
Entering either Initialization code resets all parameters to factory settings,
and automatically returns parameter
n001 setting to “ 1 ”. If the GPD 315 is
connected for 3-Wire control and this parameter is set to “ 8 ” (2-Wire
Control Initialization), the motor may run in reverse direction WITHOUT A
RUN COMMAND APPLIED. Equipment damage or personal injury may
result.
Data subject to change without notice.

- ii -
CAUTION
Parameter n012 must be set to proper motor voltage. Drive leaves factory
with this parameter set for “ 400 ” volts.
CAUTION
Always ground the GPD 315 using its ground terminal ( ) (near the main
circuit output terminals). See paragraph 1.4A, “Grounding”.
Never connect main circuit output terminals T1 (U), T2 (V) & T3 (W) to AC
main circuit power supply.
CAUTION
When drive is programmed for auto-restart ( n082 = " 1 " thru " 10 "), the
motor may restart unexpectedly — personal injury may result.
IMPORTANT
Wiring should be performed only by qualified personnel.
Always ground the GPD 315 using ground terminal ( ). See paragraph 1.4C, “Grounding”.
Verify that the rated voltage of the drive matches the voltage of the incoming power.
Never connect main circuit output terminals T1, T2, and T3 to AC main circuit power supply.
All parameters have been factory set. Do not change their settings unnecessarily.
Do not perform a “HIPOT” or withstand voltage test on any part of the GPD 315. Equipment uses
semi-conductors and is vulnerable to high voltage.
The Control PCB employs CMOS ICs which are easily damaged by static electricity. Use proper
electrostatic discharge (ESD) procedures when handling the Control PCB. Never touch the printed
control board (PCB) while the main input power is turned on.
Any modification of the product by the user is not the responsibility of MagneTek, and will void the
warranty.
Do not remove the Digital Operator or change dipswitch SW2 or rotary switch SW1 unless the main
input power is turned OFF.

1-1
The GPD 315 is a high performance sine-coded pulse width modulated special purpose AC motor
drive which generates an adjustable voltage/frequency three phase output for complete speed
control of most conventional squirrel cage induction motors. Automatic stall prevention and voltage
boost prevents nuisance tripping during load or line side transient conditions. The GPD 315 will not
induce any voltage line notching distortion back to the utility line and maintains a displacement
power factor of not less than 0.98 throughout its speed range.
When properly installed, operated and maintained, the GPD 315 will provide a lifetime of service. It
is mandatory that the person who operates, inspects, or maintains this equipment thoroughly read
and understand this manual before proceeding.
This manual primarily describes the GPD 315, but contains basic information for the operator control
station as well. For detailed operation of other units in the drive system, refer to their respective
manuals.
The GPD 315 is thoroughly tested at the factory. After unpacking, verify the part numbers with the
purchase order (invoice). Any damages or shortages evident when the equipment is received must
be reported immediately to the commercial carrier who transported the equipment. Assistance, if
required, is available from your sales representative.
If the drive will be stored after receiving, keep it in its original packaging and store according to
storage temperature specifications in Appendix 2.
Location of the GPD 315 is important to achieve proper performance and normal operating life. The
unit should be installed in an area where it will be protected from:
• Direct sunlight, rain or moisture.
• Corrosive gases or liquids.
• Vibration, airborne dust or metallic particles.
When preparing to mount the GPD 315, lift it by its base,
never by the front cover. For effective
cooling, as well as proper maintenance, the GPD 315 must be installed on a flat, non-flammable
vertical surface (wall or panel) using four mounting screws. There MUST be a MINIMUM 4.7 in.
clearance above and below the GPD 315 to allow air flow over the heat sink fins. A minimum 1.2 in.
clearance is required on each side on the GPD 315.
Make sure air entering the drive is below 122°F (50°C) by adding a fan or other cooling device, if
needed. See environmental specifications in Appendix 2.

The GPD 315 leaves the factory with all parameters set for 2-Wire external reference control. Figure
1-5 must be used for all external connections.
To use the GPD 315 in a 3-Wire application, drive parameters
n001, n003, and n004 must be
reprogrammed, using the Digital Operator. Figure 1-6 must then be used for all external connections.
A. Main Circuit Input/Output
Complete wire interconnections according to Tables 1-1 and 1-2; observe the following:
• Use 600 V vinyl-sheathed wire (75°C copper) or equivalent. Wire size should be determined
considering voltage drop of leads.
• NEVER connect AC main power to output terminals T1 ( U ), T2 ( V ), and T3 ( W ).
• NEVER allow wire leads to contact metal surfaces. Short-circuit may result.
• NEVER connect power factor correction capacitors or noise filters to GPD 315 output.
• SIZE OF WIRE MUST BE SUITABLE FOR CLASS I CIRCUITS.
• Use only factory supplied installation instructions to install optional dynamic braking resistors.
Failure to do so may cause equipment damage or personal injury.
• Motor lead length should NOT EXCEED 164 feet (50 meters), and motor wiring should be run in
a separate conduit from the power wiring. If lead length must exceed this distance, reduce
carrier frequency and consult factory for proper installation procedures.
• Use UL listed closed loop connectors or CSA certified ring connectors sized for the selected wire
gauge. Install using the correct crimp tool recommended by the connector manufacturer.
