 07/15/2009 | Are there plans to replace the P5 600V drive with a new 600V fan/pump HVAC drive? |
| 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? |
| 11/29/2005 | Can a contactor be installed between a drive and motor to start and stop the motor? |
| 11/29/2005 | The P5/506 bypass panel "Fault" light is ON, but no fault code is shown on the keypad display. What's wrong? |
| 11/28/2005 | What will happen if there is only .5'' clearance from either top or bottom of the drive to an enclosure? |
| 11/28/2005 | Do Yaskawa drives have a lock-out prohibiting setting or changing of parameters? |
| 11/28/2005 | Which PID parameters require set-up when configuring the GPD506 / P5 drive for PID pumping applications? |
| 10/28/2005 | What are the maintenance recommendations for drives that sit on shelves for a couple years without power? Should the drives be powered up from time to time? |
| 10/27/2005 | Does installation of an AC Drive near a large capacitor bank (power-factor correction) require special consideration? |
| 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 | On what applications should the GPD 506/P5 be used? |
| 10/11/2004 | Can the GPD 506/P5 be programmed in other languages? |
| 07/13/2004 | What overload protection does the GPD 506/P5V have? |
| 07/13/2004 | On a GPD 506/P5 Bypass unit, what is the Normal/Test switch used for and when would it be needed in an operation? |
| 07/13/2004 | When using the analog output function on a GPD506/P5, how is the output scaled when output current is selected? |
| 07/13/2004 | What is the purpose of a softcharge resistor and contactor in a GPD506 / P5 drive? |
| 07/13/2004 | What is the vertical and horizontal clearance specification (in inches) for mounting any of the GPD506/P5 stand alone drives? |
| 07/13/2004 | How is the kW output scaled on the Dual Analog Output option board (Model DS418)? |
| 07/13/2004 | Serial communication is lost intermittently between the building automation system (BAS) and a Lonworks board on the GPD506 / P5 drive. What might be causing this? |
| 07/13/2004 | I want the motor never to run below a certain speed and I am using PID, but there may be times when this low speed will be "too much". Is there a solution for this? |
| 07/13/2004 | The P5/GPD506 inverter is displaying an "OH2" fault that will not clear. The heat sink fan(s) is running, and the drive is cool. Why won't it clear? |
| 07/13/2004 | How can the P5/GPD506 parameter settings be adjusted or changed while the bypass drive is running in bypass mode? |
| 07/13/2004 | Harmonic current distortion data. |
| 07/13/2004 | The "sleep" function can only be used when PID is enabled. If an analog (0-10VDC or 4-20mA) signal for speed reference is used, is there any way to use "sleep" without enabling PID? |
