For master-slave applications this parameter specifies on which bus system the master transmits
the control word and the master values (P502) for the slave. On the slave, parameters (P509),
(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 Parameter Box and NORDCON.
0 = Off
No control word and and master value,
If no exclusive BUS option (e.g.
SK xU4-IOE) is connected to the
system bus, only the device
immediately connected to the
Parameter Box/NORDCON is visible.
2 = Systembus active
No control word and master value
output,
All VFDs connected to the system bus
are visible in the Parameter Box or
NORDCON even if no bus option is
connected. Prerequisite: all VFDs must
be set to this mode.
1 = CANopen (systembus)
Control words and master values are
transferred to the system bus
If no exclusive BUS option (e.g.
SK xU4-IOE) is connected to the
system bus, only the device
immediately connected to the
Parameter Box/NORDCON is visible.
3 = C systembus active
Control word and master values are
transferred to the system bus
All VFDs connected to the system bus
are visible in the Parameter Box or
NORDCON even if no bus option is
connected. Prerequisite: all other VFDs
must be set to mode { 2 } "System bus
active"

Pulse frequency
(pulse frequency)
S
3.0 ... 16.1 kHz
{ 6.0 }
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
possible motor nominal torque.
NOTE: 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.
NOTE: Raising the pulse frequency leads to a reduction of the possible output current,
depending on the time (I
2
t curve). When the temperature warning limit (C001) is
reached, the pulse frequency is gradually lowered to the default value. If the VFD
temperature drops by a sufficient amount, the pulse frequency is increased to the
original value.

NOTE:
Setting
16.1 : The automatic adaptation of the pulse frequency is activated with this
setting. When doing this, the variable frequency drive permanently determines the
maximum possible pulse frequency taking different influential factors into
consideration such as the heat sink temperature or an overcurrent warning.

NOTE: In case of overload of the variable frequency drive, the pulse frequency is
automatically reduced depending on the actual overload level to avoid overcurrent
shutdown (see also
P537 ).
With use of a sinus filter, a constant pulse frequency is required at any time as
otherwise "Module error" ( E4.0 ) shutdowns may be triggered.
The following settings are used to select the required, constant pulse frequencies.
Setting
16.2 : 6 kHz
Setting
16.3 : 8 kHz
Please note: With these settings, short circuits at the output which occur before
enabling may possibly not be detected correctly.
