Synchronous motor: Expert mode
Code Name / Description Adjustment range Factory setting
SYN- [SYNCHRONOUS MOTOR]
rSAS [Cust. stator R syn]
0 to 65,535 mOhm 0 mOhm
g
T
(1)
Cold state stator resistance (per winding). The factory setting is replaced by the result of the auto-tuning operation, if it has been
performed.
The value can be entered by the user, if he knows it.
LdS [Autotune L d-axis]
0 to 655.35 mH 0 mH
g
Axis "d" stator inductance in mH (per phase).
On motors with smooth poles [Autotune L d-axis] (LdS) = [Autotune L q-axis] (LqS) = Stator inductance L.
The factory setting is replaced by the result of the auto-tuning operation, if it has been performed.
LqS [Autotune L q-axis]
0 to 655.35 mH 0 mH
g
Axis "q" stator inductance in mH (per phase).
On motors with smooth poles [Autotune L d-axis] (LdS) = [Autotune L q-axis] (LqS) = Stator inductance L.
The factory setting is replaced by the result of the auto-tuning operation, if it has been performed.
PHS [Syn. EMF constant]
0 to 6,553.5 mV/rpm 0 mV/rpm
g
(1)
Synchronous motor EMF constant, in mV per rpm (peak voltage per phase).
PHS adjustment allows to reduce the current in operation without load.
FrSS [Nominal freq sync.]
10 to 800 Hz nSPS * PPnS / 60
g
T
Nominal motor frequency for synchronous motor in Hz unit. Automatically updated according to
[Nom motor spdsync] (nSPS) and [Pole pairs] (PPnS) data.
SPb [HF pll bandwith]
0 to 100 Hz 25 Hz
g
Bandwidth of the stator frequency Pll.
SPF [HF pll dump. factor]
0 to 200% 100%
g
Dumping factor of the stator frequency Pll.
PEC [Angle error Comp.]
0 to 500% 0%
g
Error compensation of the angle position in high frequency mode.
It increases performances at low speed in generator and motor mode, particularly for SPM motors.
AUtO [Auto] (AUtO): The drive takes a value equal to the rated slip of the motor, calculated using the drive parameters.
FrI [HF injection freq.]
250 to 1,000 Hz 500 Hz
g
Frequency of the high frequency injection signal. It has an influence on the noise during angle shift measurement and speed
estimation accuracy.
HIr [HF current level]
0 to 200% 50%
g
Ratio for the current level of the high frequency injection signal. It has an influence on the noise during angle shift measurement
and speed estimation accuracy.
MCr [PSI align curr. max]
[Auto] (AUtO) to 300% [Auto] (AUtO)
g
Current level in % of [Nominal I sync.] (nCrS) for [PSI align] (PSI) and [PSIO align] (PSIO) angle shift measurement
modes. This parameter has an impact on the inductor measurement. [PSI align curr. max] (MCr) is used for tune operation.
This current must be equal or higher than the maximum current level of the application, otherwise instability may occur.
If [PSI align curr. max] (MCr) is set to [Auto] (AUtO), [PSI align curr. max] (MCr) = 150% of [Nominal I sync.] (nCrS)
during the tune operation and 100% of [Nominal I sync.] (nCrS) during angle shift measurement in case of standard
alignment ([PSI align] (PSI) or [PSIO align] (PSIO)).
ILr [Injection level align]
0 to 200% 25%
g
Current level in % of [Nominal I sync.] (nCrS) for high frequency phase-shift angle measurement IPMA type.
