P0305 Rated motor current
Nominal motor current [A] from rating plate
Unit: A Min: 0.01
Dependency: Can be changed only when P0010=1 (quick commissioning)
Depends also on P0320 (motor magnetization current)
Note: For asynchronous motors, the maximum value is defined as the maximum VSD current (r0209).
For synchronous motors, the maximum value is defined as twice the maximum VSD current (r0209).
The minimum value is defined as 1/32 times VSD rated current (r0207).
P0307 Rated motor power
Nominal motor power [kW/hp] from rating plate
Unit: - Min: 0.01
Dependency: If P0100=1 ([kW],frequency default 50 Hz), values will be in [hp]
Can be changed only when P0010=1 (quick commissioning)
P0308 Rated motor cosPhi
Nominal motor power factor (cosPhi) from rating plate
Unit: - Min: 0.000
Dependency: Can be changed only when P0010=1 (quick commissioning)
Visible only when P0100=0 or 2, (motor power entered in [kW])
Setting 0 causes internal calculation of value (see r0332)
P0309 Rated motor efficiency
Nominal motor efficiency in [%] from rating plate
Unit: % Min: 0.0
Dependency: Can be changed only when P0010=1 (quick commissioning)
Visible only when P0100=1, (i.e. motor power entered in [hp])
Setting 0 causes internal calculation of value (see r0332)
Note: P0309=100 % corresponds to superconducting
P0310 Rated motor frequency
Nominal motor frequency [Hz] from rating plate
Unit: Hz Min: 12.00
Dependency: Can be changed only when P0010=1 (quick commissioning)
The pole pair number is recalculated automatically if parameter is changed
P0311 Rated motor speed
Nominal motor speed [rpm] from rating plate
Unit: 1/min Min: 0
Dependency: Can be changed only when P0010=1 (quick commissioning)
Setting 0 causes an internal calculation of value
Required for V/f control with speed controller
Slip compensation in V/f control requires the rated motor speed for correct operation
The pole pair number is recalculated automatically if the parameter is changed
r0313 Motor pole pairs
Displays the number of motor pole pairs that the VSD is currently using for internal calculations
Unit: - Min: -
Value: r0313=1 : 2-pole motor
Dependency: Recalculated automatically when P0310 (rated motor frequency) or P0311 (rated motor speed) is changed
P0340 Calculation of motor parameters
Calculates various motor parameters, including:
Unit: - Min: 0
Data: Calculates various motor parameters, including:
• Motor weight
• Magnetization time
• Demagnetization time P0347 (level 3)
Settings: 0=No calculation
1=Complete parameterization
2=Calc. equivalent circuit data
Note: This parameter is required during commissioning to optimize the VSD's performance
P0350 Stator resistance (line to line)
Stator resistance value in [Ohms] for the connected motor (from line to line). The parameter
value includes the cable resistance
Unit: Ohm Min: 0.00001
Data: Stator resistance value in [Ohms] for the connected motor (from line to line). The parameter value includes the cable
resistance. There are 3 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 2 times higher) than expected
The value entered in P0350 (stator resistance) is the one obtained by the method last used
r0395 CO: Total stator resistance [%]
Displays stator resistance of motor as [%] of combined stator / cable resistance
Unit: % Min: -
