| 03/14/2006 | When dealing with harmonic noise, which is better-- an AC or a DC reactor? |
| 03/14/2006 | How can I set this AC drive so my motor can’t run below 20hz? Is it the Frequency min. parameter? |

| 10/27/2005 | Can the PID in the V7 Drive be used for positioning? |
| 10/27/2005 | Does installation of an AC Drive near a large capacitor bank (power-factor correction) require special consideration? |
| 10/27/2005 | What does "with volume" and "without volume" refer to? Some V7 manuals and catalogs use this terminology. |
| 10/27/2005 | Can the V7 provide an analog output signal programmed for motor output current? |
| 10/27/2005 | Is a braking resistor internally installed? |
| 10/27/2005 | Can a motor with less capacity than the capacity of the V7 Drive be used? |
| 10/21/2005 | What does it mean when the drive has a RUN command and the STOP light is flashing on the drive display? |
| 10/11/2004 | Can a Dynamic Braking resistor be installed on a J7 Drive? |
| 07/13/2004 | 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? |
| 07/13/2004 | Can the speed reference to a V7 Drive be switched 'on the fly' between run and jog? |
| 07/13/2004 | On the V7 Drive are the Logic inputs and the Logic Common terminal (SC) electrically isolated from the Frequency Reference Common (FC)? |
| 07/13/2004 | Does the Modbus port on the V7 Drive need a termination resistor? |
| 07/13/2004 | The V7 Drive Jog Reference (S7) command is given. Why doesn't the motor move? |
| 07/13/2004 | What is the meaning of CAL or CALL on the keypad display?. |
| 07/13/2004 | What parameter sets the maximum output frequency? |
| 07/13/2004 | What happens when switching to reverse while the motor is rotating forward (FWD=OFF, REV=ON)? |
| 07/13/2004 | Why are the parameters on the digital operator hidden or locked?
|
| 07/13/2004 | What does it mean that, "motor protection time constant for the electrical termal device is 8 minutes"? |
| 07/13/2004 | Why don’t the page numbers in the parameter section of the instruction manual match the page numbers in the body of the manual?
|
| 07/13/2004 | What are some counter-measures to reduce harmonics created by AC drives? |
