PNU Description

10.25 Oscillation

Function:
Parameters P480 to P483 define the waveshape of a rectangular signal (oscillation setpoint K0203). The value set in P480 determines the
signal level for the time period set in P481 and the value set in P482 the signal level for the time period set in P483.
Oscillation: Selected in P485. The free-running rectangular signal is switched through to the output K0208.

CAUTION!
The encoders for measurement and monitoring of the brush length, bearing condition, air flow and motor temperature must be
safely isolated from the power circuit.

1) PTC thermistor according to DIN 44081 / 44082 with specified R at rated
response temperature, 1330 Ω on Siemens motors (setting 4 must be
selected). When a PTC thermistor is selected as the temperature
sensor, it is not necessary to set parameters P491 and P492 (alarm and
trip temperatures). These two temperatures are predetermined by the
type of PTC thermistor installed. Whether an alarm or fault is output
when the operating point of the PTC thermistor is reached depends on
how the relevant input is parameterized (P493.F or P494.F).
