V7N Drive

V7N Drive - YAI

1/4 - 10 HP

The V7N was a general purpose, AC motor drive for facilities using DeviceNet communications. The V7N was created by embedding DeviceNet into the control card of the highly successful V7 drive.

The embedded DeviceNet allowed for 64 network nodes. It included programmable MAC ID and baud rate. The V7N supported drive type profiles with flash capability for easy software upgrades. Network status LEDs were visible through the cover and a pluggable connector simplified wiring for added cost reduction.

The V7N Drive is a Legacy product and is no longer promoted in the Americas.

Question	Posted Date
When dealing with harmonic noise, which is better-- an AC or a DC reactor? Posted Date: 06/20/2013 Answer: Use an AC reactor when attaching a reactor to the power supply side, and a DC reactor when attaching to the series + and - bus terminals on the inverter. They are both equally effective. They can also be used in combination. Refer to the attached technical note from a manufacturer of AC chokes and DC reactors for a detailed explanation of solutions to harmonic noise in AC drives.

What will happen if there is only .5'' clearance from either top or bottom of the drive to an enclosure? Posted Date: 03/14/2006 Answer: There MUST be a minimum of 4.7'' clearance above and below the drive (varies by model) to allow airflow over the heat sink. Otherwise, an OH alarm (cooling fin overheat) may occur. Also, a minimum 1.2'' clearance (varies by model) is required on each side of the drive. Refer to the appropriate drives instruction manual for the mounting and clearance specifications.

What is the meaning of CAL or CALL on the keypad display?. Posted Date: 10/28/2005 Answer: Upon drive power up when the drives Run Command or the frequency reference are to be given from PLC thru serial communication - "CALL" will flash on the display for the VS F7/G7 - "CAL" will flash on the display for the VS mini V7/J7 This indicates the unit is awaiting the appropriate communications data. Once a node receives acceptable data from PLC, CALL or CAL will stop flashing. the drive is then ready to run.

What does it mean that, "motor protection time constant for the electrical termal device is 8 minutes"? Posted Date: 11/28/2005 Answer: This refers to Motor Overload Protection Time constant when a cold start is performed. After switching ON the power, a fault will occur if the motor runs at 150% of the load for 8 minutes. It is equal to running the motor at 150% load for 1 minute when using a hot start (after continuing to drive at 100% load). Refer to TM.V7.01 for more information.

What are some counter-measures to reduce harmonics created by AC drives? Posted Date: 06/08/2007 Answer: With inverters, some counter-measures include installing a reactor on the input side (there are both AC and DC type reactors), or the addition of a sinusoidal power supply regen converter.

In some pumping systems the motor speed is normally about 80% of rated motor speed. However, periodic purging of the pumping system requires the pump to go to full speed for a while, then return to normal. How is this done with the V7 Drive? Posted Date: 10/27/2005 Answer: The easiest way is to use the Jog Reference input, S7 to toggle between the normal speed reference and the 'Jog Frequency' (n032). Set parameter n032 to 100% frequency. Now when the Jog Reference input is energized the drive will accelerate to 100% speed. When the Jog Reference is released, the drive will return to normal speed. Note: Earlier versions of the V7 Drive were named GPD 315/V7, GPD 315 or VS Mini V7.
