⚫ PM Motor Parameter R (H106)
Set the wiring resistance (in
Alternatively, set 50% of the measured phase-to-phase resistance of the motor.
⚫ PM Motor Parameter Ld (H107)
Set the d-axis inductance (in mH) of the motor in Y-connection.
Alternatively, set 50% of the phase-to-phase inductance of the motor measured with an LCR meter.
Be sure to set this parameter so that Ld is equal to or less than Lq. Not doing so may result in an
overload.
⚫ PM Motor Parameter Lq (H108)
Set the q-axis inductance (in mH) of the motor in Y-connection.
Alternatively, set 50% of the phase-to-phase inductance of the motor measured with an LCR meter.
Be sure to set this parameter so that Ld is equal to or less than Lq.
⚫ PM Motor Parameter Ke (H109)
Set the inductive voltage parameter of your PM motor in Vp/(rad/s).
This value must be set in "Vp/(rad/s)." If the datasheet provides this parameter in a different unit, you
need to perform unit conversion.
Example
If the inductive voltage parameter for one phase is 10 [mV/r/min], the set value can be calculated as
follows:
10 [mV/r/min] = (10/1000 [V])
⚫ PM Motor Parameter J (H110)
Calculate the motor-shaft conversion of the moment of load inertia, add the moment of inertia of the
motor to it, and set the sum.
⚫ Motor Cable Length (b033)
Set the cable length from the inverter to the motor.
To maximize the performance of the inverter, set the cable length to 20 m or shorter.
