Measured Values

Torque

The torque is measured by means of a force transducer or torque measuring shaft with a
±10 V dc output or a frequency output.

Rotational Speed

The speed is measured by means of an incremental encoder with TTl or AC output;
alternatively, for example, an analog signal from a speedometer can be used.

Sense of Direction

The sense of direction is detected by means of a permanent signal (L = sense of direction
positive, H = sense of direction negative); alternatively, it can be determined using an
incremental encoder.
In this case, the following applies: if the signal is leading, the sense of direction is
positive; if the signal is lagging, the sense of direction is negative.

Configuring the Process Interface

Prior to starting the measuring process, the torque sensor and the speed sensor must be
configured. To configure the Process Interface, select menu Motor/Generator Setup. The
configuration procedure consists of the following steps:

Call Up Motor/Generator Setup

If the Power Analyzer is equipped with a process interface, menu item PI is shown
automatically in the menu.
