P503
Master function output
S
0 ... 1
[ 0 ]
The output of the master function via the system bus is activated with this parameter.
The control words and setpoint values to be output refer to the P509 source of the FI control.
The master value to be transmitted via the system bus is determined by parameter P502.
0 =
Off
1 =

P504 Pulse
frequency
S
3.0 ... 16.0 kHz
[ 6.0 ]
The internal pulse frequency for actuating the power component can be changed with this
parameter. A higher setting reduces motor noise, but leads to increased EMC emissions and
reduction of the possible motor nominal torque.
NOTE:
The radio interference suppression limiting curve A1 according to EN55011 is
complied with at a setting of 6.0kHz on condition that the wiring guidelines are
complied with. For further details, see Section 8.4. EMC limit value classes.
NOTE:
Raising the pulse frequency leads to a reduction of the possible output current,
depending on the time (I
2
t curve). For further details, see Section 8.5. Power de-
rating.
