YASKAWA GPD515C, Техническое руководство

Страница: 2 / 26

The GPD 515/G5, hereafter referred to as the drive, is a general purpose sine-coded pulse
width modulated 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 drive 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 drive 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 515/G5, but contains basic information for the
operator control station as well. This manual is equally applicable to drives labelled
GPD 515 or G5.
The drive 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 drive 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 drive, lift it by its base, n e v e r by the front cover. For
effective cooling as well as proper maintenance, the drive 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 drive to allow air flow over the heat sink
fins. A minimum 1.2 in. clearance is required on each side on the drive.
A GPD 515/G5 in a free-standing floor-mount cabinet must be positioned with enough
clear-ance for opening the door of the cabinet; this will ensure sufficient air space for
cooling. Make sure air entering the drive is below 113°F (45°C) (for protected chassis
drives), or below 104°F (40°C) (for NEMA 1 drives), by adding a fan or other cooling
device, if needed. See environmental specifications in Appendix 2.
