Setting Description
- Input of the cos phi of the motor according to motor name plate.
Setting Description
400 V Input of the motor rated voltage according to motor name plate.
Setting Description
x Basic position before and after the automatic calibration.
• Bring motor to working temperature
• Activate calibration mode by setting „1"
• Set drive command (e.g. return)
• Set control release
• Press UP (▲) -key in Ld.08 once shortly
• The calibration starts and is completed after approx. 10 s
• Ld.08 displays now the measured value
• Cancel the drive command
• Open control release, thereby the measure procedure is finished
Setting Description
249,99 Ω With this parameter the direct input of the motor winding resistance can be
made.
Measure with a multimeter:
The motor resistance is measured, independent of the motor connection (∆/Y),
between two phases of the motor feed line. That way the ohmic line resistance
is recorded at the same time (important in case of long feed lines). At that the
motor should be at working temperature.
Input of the motor winding resistance according to data sheet:
When taking the motor resistance from a data sheet, the R120 - equivalent
resistance (phase value) is mostly specified there. Then the following values,
depending on the used connection, must be adjusted in Ld.08 :
Star connection: Ld.08 = 2 • R1
Delta connection: Ld.08 = 0,666 • R1
If only the warm resistance R1W is specified:
Star connection: Ld.08 = 1,4 • R1
Delta connection: Ld.08 = 0,46 • R1
Setting Description
x,x mH Input of the leakage inductivity of the motor winding.
When taking the leakage inductivity from a data sheet, the phase value for
σLS is mostly specified there. Then the following value, depending on the
used connection, must be entere in Ld.09:
Star connection: Ld.09 = 2 x σLS
Delta connection: Ld.09 = 2/3 x σLS
Setting Description

data sheet. The value is automatically calculated at asynchronous machines
