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.
