4.4.16 TenMax_EU
This is the maximum tension for the section. Maximum tension is usually determined
by the machine builder and/or motor rating and gear ratio. Pounds and ounces are
typical units for the Imperial System. Newtons are typical units for the metric system.
Usage - Connect to the Maximum Tension tag or set the value of Maximum Tension
in the JSR instruction
4.4.17 RadiusCalc_EU
This is the Radius of the roll controlling tension. For a variable diameter section, this
value will be calculated from the diameter calculator. The units need to match the
same units as Line Speed Max (see below). Typical units are feet (Imperial) or
meters (Metric).
Usage - Connect to the Calculated Radius tag or set the value of Radius in the JSR
instruction.
4.4.18 GearRatio
The gear ratio of the machine section.
Usage – Connect to the gear ratio tag or set the value of gear ratio in the JSR
instruction.
4.4.19 MtrTrqRated_EU
This is motor rated torque in engineering units. The engineering units for this term
must match with the engineering units for TenMax_EU and RadiusCalc_EU. For
example if the tag TenMax_EU has units of pounds and the RadiusCalc_EU has
units of feet, than the units for motor rated torque would be foot-pounds.
The Motor Rated torque can be calculated using the motor’s nameplate data. For
Imperial Units (Foot-Lbs), the equation is the following:
For Metric Units (Newton-Meters), the equation is the following:
Note: Application Module users, The rated motor torque is calculated by the program.
Usage – Connect to the Rated Motor Torque tag or set the value of Rated Motor
Torque in the JSR instruction.
4.4.20 LineSpdMax_EU
This is the Line Speed Maximum in engineering units.
Usage – Connect to the Line Speed Max tag or set the value of Line Speed Max in
the JSR instruction.
