1-1This document pertains to the V7 ac drive. This manual reflects the Software Version 0028 formodels CIMR-V7▫▫▫0P1 through V7▫▫▫4P0 and Software Version 0106 for models CIMR-V7▫▫▫5P5and V7▫▫▫7P5. This document is equally applicable to drives identified as GPD315, GPD315/V7,GPD315/V74X, and V74X. Additionally, in this document, the word “drive”, “ac drive”, and “inverter”may be used interchangeably. The V7 (NEMA type1) and V74X (NEMA type 4X/12), hereafterreferred to as the "Drive," are general purpose sine-coded pulse width modulated AC motor driveswhich generate an adjustable voltage/frequency three phase output for complete speed control ofmost conventional squirrel cage induction motors. Automatic stall prevention and voltage boost pre-vent nuisance tripping during load or line side transient conditions. The Drive will not induce anyvoltage line notching distortion back to the utility line, and it maintains a displacement power factor ofnot less than 0.98 throughout its speed range.When properly installed, operated and maintained, the Drive will provide a lifetime of service. It ismandatory that the person who operates, inspects, or maintains this equipment thoroughly read andunderstand this manual before proceeding.Information in this manual covers both the NEMA type 1 and NEMA type 4X/12 configuration of theDrive. It also contains basic information for the operator control station. For detailed operation ofother units in the drive system, refer to their respective manuals.The Drive is thoroughly tested at the factory. After unpacking, verify the part numbers on the name-plate with the purchase order (invoice). Any damages or shortages evident when the equipment isreceived must be reported immediately to the commercial carrier who transported the equipment.Assistance, if required, is available from your sales representative.Do not install a drive that is damaged or missing parts.If the drive will be stored after receiving, keep it in its original packaging and store according tostorage temperature specifications in Appendix 2.Location of the Drive is important to achieve proper performance and normal operating life. The unitshould be installed in an area where it will be protected from:• Extreme cold and heat. Use only within the ambient temperature range (for open chassistype): 14 to 122°F (-10 to +50°C)• Rain, moisture• Oil sprays, splashes• Salt spray• Direct sunlight. (Avoid using outdoors)• Corrosive gases (e.g. sulfurized gas) or liquids• Dust or metallic particles in the air• Physical shock, vibration• Magnetic noise (Example: welding machines, power devices, etc.)• High humidity• Radioactive substances• Combustibles: thinner, solvents, etc.When preparing to mount the Drive, lift it by its base, never 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 3.9 in. clearance aboveand below the Drive to allow air flow over the heat sink fins. A minimum 1.2 in. clearance is requiredon each side of the Drive.Section 1.
