Dancer control overview
Performs dancer control by setting 40 to 43 in Pr. 128 "PID action selection". The main speed com-
mand is the speed command of each operation mode (external, PU, Network). Performs PID control by
the position detection signal of the dancer roller, then the result is added to the main speed com-
mand. For acceleration/deceleration of the main speed, set the acceleration time in Pr. 44 "Second ac-
celeration/deceleration time" and the deceleration time in Pr. 45 "Second deceleration time".
Set 0s normally to Pr. 7 "Acceleration time" and Pr. 8 "Deceleration time". When the Pr. 7 and Pr. 8 set-
ting is large, response of dancer control during acceleration/deceleration is slow.

Connection diagram
The following figure shows a typical application example:
Pr. 128 = 41
Pr. 182 = 14
Pr. 190 = 15
Pr. 191 = 14
Pr. 192 = 16
Fig. 6-159: Example in source logic
The main speed command differs according to each operation mode (external, PU,
communication).
The used output signal terminal changes depending on the Pr. 190 to Pr. 192 "Output terminal
selection" setting.
The used input signal terminal changes depending on the Pr. 178 to Pr. 184 "Input terminal
selection" setting.
The AU signal need not be input.
