Description
The port (on the local computer) on which the system
listens for new minor errors, which occurred on the
remote computer.
The port (on the local computer) on which the system
listens for new major errors, which occurred on the
remote computer.
The default port on the remote computer to which the
local computer sends commands and configuration data
(e.g. start/stop measuring). This value is just the default
value. It has no effect on the remote computer. The
actual port to which the local computer sends commands
needs to be configured when connecting to the remote
computer.
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a torque with
the real word unit Newton-meter.
A torque can also be measured even when no load is
applied. This torque is a function of the motors
frequency. The software calculates with the frequency
of the motor x (in rounds per minutes) and this formula
a correction value. This value is subtracted from the
measured torque in Nm.
correction value [Nm] = f(frequency of the motor [rpm])
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a normal force
with the real world unit Newton.
With the rising temperature the normal force falls due to
thermal expansion of the geometry. The software
calculates with the oven temperature (in °C) and this
formula a correction value. This value is subtracted from
the measured normal force in Newton.
correction value [N] = f(oven temperature [°C])
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a normal force
with the real world unit Newton. This formula is used
instead of the above formula when the “room
temperature force module” is installed.
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a normal force
with the real world unit Newton. This formula is used
for the normal force channel of the “room temperature
force module”.
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a friction force
with the real world unit Newton. This formula is used
for the friction force channel of the “room temperature
force module”.
The measured signal x (in volts) will be evaluated with
this formula. The result is interpreted as a current with
the real world unit Ampere.
