SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the minimum time for falling below the changeover speed when changing from closed-loop controlled opera-
tion to open-loop controlled operation.
Dependency: Refer to: p1755, p1756
Description: Sets the minimum time for exceeding the changeover speed when changing from open-loop controlled operation to
closed-loop controlled operation.
Dependency: Refer to: p1755, p1756
Note: When p1759 = 2000 ms, the delay time becomes ineffective and the model changeover is determined by the output
frequency only.
Description: Induction motor (ASM):
Displays the referred imaginary system deviation for the adaptation circuit of the motor model.
Permanent-magnet synchronous motor (PESM):
Displays the system deviation for speed adaptation.
r1762.0: Angular deviation [rad-el] of the estimated EMF.
r1762.1: Angular deviation [electr. deg.] of the low-level signal response for pulse technique.
Index: [0] = Deviation Model1
[1] = Deviation Model2
Description: Induction motor (ASM):
Displays the referred real system deviation for the adaptation circuit of the motor model.
Permanent-magnet synchronous motor (PESM):
Not used.
