Dancer control block diagram
The main speed can be selected from all operation mode such as external (analog voltage
input, multi-speed), PU (digital frequency setting), communication (RS485).

NOTES
Changing the terminal function using any of Pr.178 to Pr.182 may affect the other functions.
Make setting after confirming the function of each terminal.
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Differ-
ent setting may cause a fault, failure or malfunction. (Refer to page 6-148 for setting.)
