Pm Motor Resistance; Pm Motor Inductance - KEB COMBIVERT F5 Instruction Manual

Parameter Description - Motor Data
PM motor resistance
PM motor inductance
86
This parameter not required for closed loop induction motor
IM
operation and will not be visible in these modes.
For PM motors enter the phase to phase resistance value.
Some motor manufacturers list the per phase value therefore
PM
you must multiply by two. This value can also be measured
by the drive's auto-tune function, see parameter LF.3. Incorrect
settings of this parameter could lead to oscillation in the current
control and audible noise in the motor, since the regulator values
for the current control are calculated from this value.

This information is not used for induction motors and therefore
IM
the parameter is not visible in induction motor mode.
This is the total phase to phase reflected leakage inductance of
PM
the motor winding. The inductance listed on the manufacturer's
data sheet will most likely be for one phase. So it will be necessary
to multiply the value by two and then enter it into the drive. This
value can also be measured by the drive's auto-tune function,
see parameter LF.3. Incorrect settings of this parameter could
lead to oscillation in the current control since the regulator values
for the current control are calculated from this value.
