P0340 Calculation of motor parameters
Min: 0 Def: 0 Max: 4
Level 2
Data: Calculates various motor parameters, including:
Motor weight P0344 (Level 3)
Magnetization time P0346 (Level 3)
Demagnetization time P0347 (Level 3)
Stator resistance P0350 (Level 2)
Reference frequency P2000 (Level 2)
Reference current P2002 (Level 3).
Enum: 0=No calculation
1=Complete parameterization
2=Calc. equivalent circuit data
3=Calc. V/f and vector control
4=Calc. only controller setting
Note: This parameter is required during commissioning to optimize inverter performance.
P0350 Stator resistance (line-to-line)
Min: 0.00001 Def: 4.0 Max: 2000.0
Level 2
Data: Stator resistance value in [Ohms] for connected motor (from line-to-line). The parameter value includes the cable
resistance. There are three ways to determine the value for this parameter:
1. Calculate using P0340=1 (data entered from rating plate) or P3900=1, 2 or 3 (end of quick commissioning)
2. Measure using P1910=1 (motor data identification-value for stator resistance is overwritten)
3. Measure manually using an Ohmmeter.
Note: Since measured line-to-line, this value may appear to be higher (up to two times higher) than expected.
The value entered in P0350 (stator resistance) is the one obtained by the method last used.

P0400 Select encoder type
Min: 0 Def: 0 Max: 12
Level 3
Settings: 0=Disabled
1=Single channel encoder
2=Quadrature encoder without zero pulse

degrees.
