In tension control system, it is crucial to detect the line speed accurately. At present, there are
three sources for line speed signal:
‹ Analog Input (AVI, ACI, AUI)
The full-scale value of analog input corresponds to maximum line speed (set in Pr.10-38).
The most common way is to use AFM of master driver (rotation speed is in direct
proportion to line speed) as the line speed signal.
‹ Communication Setting
When it is set to 04, the current line speed can be directly input to Pr.10-41 via RS-485
communication.
‹ Pulse Input
Encoder can be used to detect the line speed or use DFM of master driver (rotation speed
is in direct proportion to line speed) as the line speed signal.
When it is set to 05, pulse signal needs to be input to PG03 through channel B and use
with Pr.10-40.
When it is set to 06, pulse signal needs to be input to PG03 through channel B and use
with Pr.03-07, which should be set equal to Pr.03-07 of master driver.
