7.4.2 Example telegrams
Various example telegrams are shown below to clarify the control and parameterisation of the frequency
inverter with the various field bus systems.
7.4.2.1 Example for switching the frequency inverter on and off
In this example, a FI will be operated with a setpoint (setpoint frequency) and an actual value (actual
frequency). The "maximum frequency" is 50Hz.
Parameter settings:
 P105 = 50
 P543 = 1
 P546 = 1

The FI is enabled, the motor is supplied with current and rotates with a frequency of 12.5Hz.
7.4.2.2 CANopen with USS process data
The following example is designed to clarify control using PDOs. The following settings are assumed:
 FI 1 on field bus module SK xU4-CAO
 Node-ID
"4"
 Parameter (P509) "Source control word"
for SK500E: Setting: {6} "CANopen control word" (object number (21FD
hex
) = 6) or
for SK200E: Setting: {3} "System bus" (object number (21FD
hex
) = 3,
(P510)= {0}
 Rx-PDO1 is used for control. The device transmits its actual values via Tx-PDO1
 The drive profile is disabled
for SK 500E: Setting: (P551) = {0} or
for SK200E: Setting: (P168 [-01]) = {0}
