When replacing the motor for the application and the heat sink cooling fans. How do I reset Cumulative Motor Operation Time U1-13 and Heat Sink Cooling Fan Operation Time U1-40? Posted Date: 09/16/2013 Answer: When a motor replacement is needed, Cumulative Motor Operation Time (U1-13) can be reset with setting parameter o2-07=000000. When replacing the heat sink cooling fans on the drives, Heat Sink Cooling Fan Operation Time (U1-40) can be reset with setting parameter o2-10=00000.

When reading 42h it does not match U1-03? Using Ethernet or Modbus protocols. Posted Date: 08/31/2012 Answer: When using 42h, please use the following formula: "Value of Read" divided by "8192" times "Drives Rated Output Current". You can also read 26h which does not require this formula.

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.

How to program HOA for P7 drive? Posted Date: 07/17/2012 Answer: Pending on the digital operator you have you will not be able to use HOA in a P7 drive. JVOP-160 will not allow HOA function because there is no HAND or AUTO button. -Work around - wiring Cust would have to wire up terminal S5 and SN for Multi speed ref. This will toggle between D1-01 and A2. Analog ref would now be wired to A2 and AC. (Make sure S1 dip switch is set correctly according to H3-08) Set B1-01 =00 D1-01 = Desired speed H1-03 = 3 H1-04 = 4 H3-08 = 0 for 0-10vdc, 1 for 4-20ma H3-09 = 2 Product Group/Line: Inverter Drives, P7 Drive Topic/Sub Topic: Ask a Technical Question, Programming Document Number: DRV-8W4LSR Published Date: 07/17/2012	07/17/2012
