Example of how to determine the “new value”
Suppose “64” was the value found here. Converted to BCD, this is 0110 0100 (0110 binary is 6
decimal, 0100 binary is 4
decimal). 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.

Remove and re-apply main power to the drive after the above programming is finished.
In a normal PID scenario, the error signal the PID acts upon is the setpoint command minus the feedback;
with the above programming, the dancer PID acts upon the feedback (RX) only and tries to maintain it at
the zero setting. Therefore, any speed reference (from the RR or IV terminals, for example) has no effect
on drive output frequency when PID is on. NOTE, HOWEVER, THAT PID WILL NOT BE ACTIVE IF
THE SPEED REFERENCE IS ZERO (make sure the RR or IV terminals or other frequency reference
source are commanding at least 0.01 Hz. The actual value does not matter).
