Configure Torque Sensor
The torque can be measured by means of force transducers or a torque-measuring shaft.
The signal is transferred via a ±10 V AC output or a frequency output. In line M, (for
example, motor 1: M1), adjust the following settings:
Column Settings Description
Gain 1... Slope
Unit Nm/Hz
Nm/V
Depending on force transducer or sensing shaft type
Zero 1... Voltage or frequency corresponding to speed = 0
Unit Hz, V Unit for zero, depending on sensor type
1. Move the cursor to a field in line M1 and press Enter.
A list of possible options is displayed.
2. Select a value and press Enter to confirm.
The value is now shown in the display field.
Configure Speed Sensor
Possible speed sensors include the incremental encoder (measuring with TTL / AC
output) or an analog signal. In line n (for example, motor 1: n1), adjust the settings:

1. Move the cursor to a field in line n1 and press Enter.
A list of possible options is displayed.
2. Select a value and press Enter to confirm.
The value is now shown in the display field.
Configure Motor or Generator
