∗1
Set the parameter according to the specification of the machine used.
∗2
The increment applies when Pr.21 = "0 (initial value)".
∗3
The increment applies when Pr.358 = "0 (initial value)".
Parameter setting procedure for speed control of intermediate shafts
Set the roller (reel) diameter of the intermediate shaft in millimeters in both
Pr.1235 and Pr.1236.
Set the acceleration time in 0.1 second
Set the deceleration time in 0.1 second
Set "0" (Line speed command).
Set the reference line speed (travel amount per minute) in 0.1 m
for the acceleration/deceleration time for the line speed command.
To assign the Tension control selection (X114) signal, set "114" in any of the
parameters.
To assign the Line speed acceleration (Y237) signal and the Line speed
deceleration (Y238) signal, set "237" and "238" in any two of the parameters.
Set "0".
Set "0".
Set "9999" (Winding diameter calculation disabled).
Set "26" (Line speed command value).
Set the line speed (travel amount per minute) in 0.1 m
maximum (100%) output via terminal AM.
Set a gear ratio when the motor shaft has a reduction gear. (The increment is 1
for each parameter.)
Set "9999" (Function disabled).
Set "40".
Set "9999" (Without proportional control).
Set "9999" (Without integral control).
Set "9999" (Without differential control).
The initial value is "0" (m/min).
Choose an appropriate value (increment) according to the specifications of the
machine used.
The Y237/Y238 signal output range can be set for the target line speed
command. (Refer to
