Factory setting
It is only possible to change the motor standard during quick commissioning.
6.3.10.2 Unit system
Some physical units depend on the system of units selected (SI or US), for example the power
[kW or hp] or the torque [Nm or lbf ft]. You can select in which system of units the converter
represents its physical values.
Options when selecting the system of units
The following options apply when selecting the system of units:
● p0505 = 1: System of units SI (factory setting)
Torque [Nm], power [kW], temperature [°C or K]
● p0505 = 2: Referred system of units/SI
Represented as [%]
● p0505 = 3: US system of units
Torque [lbf ft], power [hp], temperature [°F]
● p0505 = 4: System of units, referred/US
Represented as [%]
