Master function output
P503
(Master function output)
For master-slave applications this parameter specifies on which bus system the master transmits
0 ... 3
the control word and the master values (P502) for the slave. On the slave, parameters (P509),
{ 0 }
(P510), (P546 ) define the source from which the slave obtains the control word and the master
values from the master and how these are to be processed by the slave.
Specification of communication mode on the system bus for ParameterBox and NORDCON.

Pulse frequency
P504
(Pulse frequency)
3.0 ... 16.1 kHz The internal pulse frequency for controlling the power unit can be changed with this parameter.
A higher setting reduces motor noise, but leads to increased EMC emissions and reduction of the
{ 6.0 }
possible motor nominal torque.

0 = Off
No control word and master value
output,
If no individual BUS option (e.g.
SK xU4-IOE) is connected to the
system bus, only the device directly
connected to the ParameterBox or
NORDCON is visible.
1 = CANopen (system bus)
Control word and master values are
transferred to the system bus.
If no individual bus option (e.g.
SK xU4-IOE) is connected to the
system bus, only the device directly
connected to the ParameterBox or
NORDCON is visible.
The best possible degree of interference suppression for the device is adhered to by
using the default value and taking the wiring directives into consideration.
Raising the pulse frequency leads to a reduction of the possible output current,
depending on the time (I
reached, the pulse frequency is gradually lowered to the default value. If the inverter
temperature drops by a sufficient amount, the pulse frequency is increased to the
original value.
Setting 16.1: The automatic adaptation of the pulse frequency is activated with this
setting. When doing this, the frequency inverter permanently determines the
maximum possible pulse frequency taking different influential factors into
consideration such as the heat sink temperature or an overcurrent warning
2 = System bus active
No control word and master value
output,
All FIs connected to the system bus
are visible in the ParameterBox or
NORDCON, even if no bus option is
connected. Prerequisite: all FIs must be
set to this mode.
3 = CANopen + system bus active
Control word and master values are
transferred to the system bus
All FIs connected to the system bus
are visible in the ParameterBox or
NORDCON, even if no bus option is
connected. Prerequisite: all other FIs
must be set to mode { 2 } "System bus
