9.1.10 TR Grey – Scaling parameter
Risk of physical injury and material damage due to shifting of the zero
point when the measuring system is switched on again after positioning
in de-energized state!
The zero point of
the multiturn measuring system may be lost if more than
32767 revolutions are executed in de-energized state!
• Make sure that positioning operations in de-
energized state take place
within 32767 revolutions on a multiturn measuring system.
• If this cannot be
ensured, the issued position must first be verified with the
desired mechanical position before the application can be started.
The physical resolution of the measuring system can be changed by using the scaling parameters
– TR Grey – Measuring Range
– TR Grey – Revolutions Numerator
– TR Grey – Revolutions Denominator
The measuring system supports the gear function for rotary axes.
This means that the number of steps per revolution and the quotient of Revolutions numerator
/ Revolutions denominator can be a decimal number.
The output actual position value is offset by a zero-point correction, the set counting direction and the
entered gearbox parameter.
MEASURING RANGE
Defines the total number of steps of the measuring system, before the measuring system restarts at 0.
UDINT
Lower limit
2 steps
Upper limit
536 870 912 steps (30 bits)
Default
536870912
The actual upper limit value to be entered for the measuring range in steps depends on the
measuring system design and can be calculated using the formula below. As the value "0" is already
counted as a step, the end value = measuring range in steps – 1.
Measuring range = steps per revolution * number of revolutions
For the purposes of calculation, the parameters Steps/Revolution and Number of Revolutions can
be taken from the measuring system nameplate.
