 To configure the system for motor 1, go to "Configure torque
sensor"
– or –
 To configure another motor, press Next ... until the
respective motor code (M2, M3 or M4) is displayed.
The torque can be measured by means of force transducers or a
torque-measuring shaft. The signal is transferred via a ± 10V AC
output or a frequency output. In line M.. (e.g. for motor 1: M1),
adjust the following settings:
