The dancer trims the drive’s output frequency a maximum of +/- 12.5 % of the Maximum Output
Frequency
(2)
The following is an example of how to adjust the RX Bias/Gain:
Suppose dancer output is 1-5 volts. 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 2.5
volts. 2.5/5.0 = 0.50 or 50 percent. Enter 50 into RX Reference Setting Point #1 (FREQUENCY
SETTING PARAMETERS group). After the following Super
User programming is done, the drive
will automatically adjust its output frequency to maintain the dancer’s output voltage
(and therefore
position) at 2.5 volts.
(3)
These are suggestions and will have to be field-adjusted. See Application Guideline 24 for PID
information
With the RX Bias/Gain programmed as above, the drive will increase its output frequency when the
dancer voltage is above 2.5 volts; it will decrease its output frequency whenever the dancer voltage is
below 2.5 volts. If this relationship is the opposite of what is desired for a particular dancer, program RX
Reference 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 volts
and decrease its output frequency whenever the dancer voltage is above 2.5 volts.

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 binary
is 4 decimal). Process dancer control is turned on by setting the leftmost bit to ‘1’, so the new BCD values will be
1
110 0100, which is E4 in hex. Use the up arrow to adjust the 64 to read E4.
