Set the micro switch next to the phone jack on the control board in the‘5” position. Suppose that the dancer output voltage when the dancer is in the desired position is 2.5volts. 2.5/5.0 = 0.50 or 50 percent. Enter 50 into RX Reference Setting Point #1 (FREQUENCYSETTING PARAMETERS group). After the following Super User programming is done, the drivewill automatically adjust its output frequency to maintain the dancer’s output voltage (and thereforeposition) at 2.5 volts.(3) These are suggestions and will have to be field-adjusted. See Application Guideline 24 for PIDinformationWith the RX Bias/Gain programmed as above, the drive will increase its output frequency when thedancer voltage is above 2.5 volts; it will decrease its output frequency whenever the dancer voltage isbelow 2.5 volts. If this relationship is the opposite of what is desired for a particular dancer, program RXReference Point #2 Frequency (FREQUENCY SETTING PARAMETERS group)to ‘-60’. Now the drive will increase its output frequency whenever the dancer voltage is below 2.5 voltsand decrease its output frequency whenever the dancer voltage is above 2.5 volts.Additional ProgrammingKEYSTROKE RESULTING DISPLAYLOCAL/REMOTE OUTPUT FREQUENCY0.0 HzREAD/WRITE OUTPUT FREQUENCY0.0 HzREAD/WRITE hold down OUTPUT FREQUENCY0.0 HzLOCAL/REMOTE GROUP: SUPERUSERREAD/WRITE RAMFdown arrow RAMdown arrow EEPREAD/WRITE 0380up arrow until 04B9READ/WRITE somethingarrows until (4) new valueREAD/WRITE 04B9 alternating with new value, then 04B9PRG OUTPUT FREQUENCY0.0 Hz(4) Example of how to determine the “new value”Suppose “64” was the value found here. Converted to BCD, this is 0110 0100 (0010 binary is 6 decimal, 0100 binaryis 4 decimal). Process dancer control is turned on by setting the leftmost bit to ‘1’, so the new BCD values will be1110 0100, which is E4 in hex. Use the up arrow to adjust the 64 to read E4.
