Step 2 Setting the tension command value
Set a tension command value calculated per Step 1 under each of eight operation data numbers from 0 to 7.
When the system parameter for analog input signals [SyS-1-05] is set to “Enable,” two analog points and six
digital points are available to assign settings. If the parameter is set to “Disable,” eight digital points are
available to assign settings.

Note
If operation data No. 0 is selected for tension controlled operation, the speed limit value
(p.120) set under operation data No. 0 will also be selected. Different operation data
numbers cannot be selected for the two parameters.
Select a desired tension command value from among the predefined settings, based on a combination of
ON/OFF statuses of M0 to M2 inputs.

Using the internal potentiometer VR1
1.
Set the system parameter for analog input signals [SyS-1-05] to “Enable.”
Note
When a system parameter has been changed, the new parameter will become
effective after the power is cycled. If a 24 VDC power supply is used, also cycle the
24 VDC power supply.
2.
Turn the M0 to M2 inputs OFF and select operation data No. 0.
3.
Set the tension command value using the
internal potentiometer VR1.
