About the 3v4140
The 3V4140 drive Reliance Electric drive is an AC, pulse width modulated drive that can provide both vector regulation and general purpose regulation for a large range of industrial applications. This unit can provide operators with a highly rated, dynamic response and be able to maintain the motor control functionalities in a precise manner. While many of the GV3000 drives have a regulator version of 6.0, the 3V4140 model operates on a regulator version of 4.0.
The 3V4140 is a three-horsepower AC drive and includes a three-phase AC line distribution system with a symmetrical fault current capacity of 85,000 amperes. The AC line reactor has a line impedance rated at less than 5 percent.
The 3V4140 drive has a line frequency range from 50 to 60 hertz (rated at plus or minus 5 hertz) and a line voltage variation range from -10 to 10 percent.
The 3V4140 is designed with an operational temperature range of 0 to 40 degrees Celsius or 32 to 104 degrees Fahrenheit. When powered off in storage, the temperature range is expanded to -40 to 65 degrees C or -40 to 149 degrees F.
Owners of this GV3000 series drive can expect a number of installation and usage-based faults in drive function. One such fault encountered by users of the 3V4140 can be described as a communication loss between the drives' Regulator, PC, and OIM. Represented on the built-in display interface as SrL, this fault is caused by an error in serial port communication cable, PC or OIM communication port setup. Corrective action when faced with this common fault would be to check on the setup of the communication ports and port cables, to ensure proper connections. For more information on fault code troubleshooting and general drive programming, please access the D2-3324-1 instruction guide.
This model has a regulator board built in; the regulator board is used to provide a variety of features, such as an analog output, snubber resistor braking signals, form A and B contacts for drive status indicators, and PWM gating signals to the IGBT power devices. The analog output associated with the 3v4140 model is used for scaling voltages, 0-10 VDC, or a current signal of 1-20 mA, which will be proportional to the motor torque/current or motor speed. More information on the above features in relation to the regulator board can be found in the D2-3324-1 GV3000 AC Power Module Reference, Installation, and Troubleshooting Manual attached above.
