Remarks
7: External thermal relay input (OH) signal (Setting "7" is
required for signals input from the SF-V5RU thermal
protector.)
Setting 0% is required to disable additional input to the
dancer signal (compensation for addition via terminal 1) while
the X114 signal is OFF and the normal operation is carried
out.
Use Pr.358 to set the increment.
Use Pr.358 to set the increment. Maximum line speed (2000
m/min) is set.
0: m/min (increment of the maximum line speed)
If setting Pr.361 to "8", set a line speed command value in this
parameter.
0: Signals for the actual line speed are not input (the actual
line speed is determined by calculating from the line speed
setting).
5: Dancer signals input via terminal 1.
Setting must be lower than the acceleration/deceleration rate
of the line speed command (input via terminals 2 and 5).
(In this example, setting these parameters are not required as
the cushion time is considered for the line speed command.
However, 0.5 seconds is set as a precaution against noise.)
Setting this parameter avoids intermittent operation after the
initial roll diameter calculation is completed.
By adjusting the speed control proportional gain, response
improvement is achievable according to the roll diameter.
Pr.644 (proportional gain for the maximum roll diameter) and
Pr.641 (proportional gain for the minimum roll diameter) are
used for determination of the setting of Pr.642 and Pr.643.
Pr.642 = α/5 + Pr.641
(
Pr.643 = 8 × α/15 + Pr.641 α = Pr.644 - Pr.641)
When "1" (storing roll diameters enabled) is set, the input of
the Stored winding diameter clear (X109) signal is required.
The storing of roll diameters (writing in EEPROM) is
conducted when the inverter power or the X114 signal turns
OFF.
Note that the storing is not conducted when the RES signal is
input. Therefore, avoid inputting the RES signal frequently
without storing the roll diameters.
For the input of the RES signal by necessity such as a reset
of the inverter fault, it is recommended to configure the
sequence that the RES signal will be input after the X114
signal turns OFF and before the X114 signal turns ON again.
Be sure to set this parameter when storing roll diameters is
set to enabled (the value of the stored roll diameter is not
applied to any setting if this parameter is not set).
0: Vector control (speed control)
Set 0 seconds to disable the integral so that the inverter acts
as a proportional amplifier.
Set this parameter when noise is superimposed on the input
analog signals.
Use this parameter to decrease whining sound of a motor at a
stop.
