4.2.6.3 Use of the temperature detection
The temperature detection provides the user all possibilities within the resistance
range specified in
„Temperature detection terminals T1, T2“
. This can be:
Thermal contact (NC contact)
e.g. at the brake resistor
T1
T2
Temperature sensor (PTC)
e.g. at motor temperature detection
T1
T2
Mixed sensor chain
T1
T2

4.2.7 final test information
Final test information of the machines/systems which are provided with drive converters
according to
4.3 calculation of the motor voltage
The motor voltage for dimensioning of the drive is depending on the used components.
The mains voltage reduces according to the following table:
