19.30 Slip frequency actual temperature
(This is relevant at asynchronous motors with an encoder if the temperature monitoring
is active,
Z128.2– bits 0 to 7).
Slip frequency of the motor at nominal torque current and nominal flux (magnetic flux =
100%) according to the motor temperature actual value
Z128.3–. The parameter is cal-
culated by the temperature adaption characteristic and is used to determine the "Slip pre-
set value" (Z146.16–). See ZTemperature adaption slip frequency– on page 508.
19.32 Rotor time constant
Display of the rotor time constant for the asynchronous motor; required for flux control.
The value is calculated from the magnetic current Z107.14–, the nominal current
Z107.9– and the slip frequency cold Z107.15–.
Has no significance for synchronous motors.
19.50 Notch position O.K.
19.51 Current ref. for notch position detection
Current for the notch position detection.
Standardization:
100% = Motor Nominal current Z107.9–
Bit Meaning
0 Plausibility O.K. (Absolute encoder present)
1 Notch position search active
2 Notch position search ended
3 Notch position search failed or plausibility error
