2.2.2 Profibus module SK TU1-PBR
This Profibus module is internally
supplied from the frequency inverter.
Therefore, this Profibus participant is
only detected by the master system
if mains voltage is applied to the
frequency inverter.
Termination resistor
The termination resistor for the last
bus participant is located in the
Profibus standard plug.
A transfer rate of up to 1.5Mbit/s can
be used.
Profibus LED display
Further information regarding the
status LED displays is listed in
Section 8.2.

2.2.3 Profibus module SK TU1-PBR-24V
This Profibus module is supplied with voltage by an external 24V
connection. The Profibus participant can therefore be identified by
the master system even without a power supply to the frequency
inverter. The data required for this purpose are set using a rotary
coding switch. The data is read in when the 24V are applied.
A transfer rate of up to 12Mbit/s can be used.
Connection of the supply voltage
The supply voltage is 24V DC ±25% (Terminal 45 = 24V, terminal 46
= GND, approx. 100mA). Connection is via screw terminals with a
maximum conductor cross-section of 2.5mm². Wire end sleeves must
be used for flexible cables.
The assignment of the socket is identical to that for the option SK
TU1-PBR.
Termination resistor
The termination resistor for the last bus participant is located in the SUB-D9 Profibus standard plug.
Profibus LED display
Further information regarding the status LED displays is listed in Section 8.2.
Setting the PPO type
The 4 PPO types can be selected with the rotary coding switch for the PPO type (Section 7.2 and
7.2.1).
1 to 4 means the address range 00 to 99. With +100, the addresses from 100 to 126 can be set.
When set to PGM the value from parameter P507 of the frequency inverter is used. For this, the
frequency inverter must be supplied with mains voltage.
