5.2 Parameterisation of the bus module (SK CU4-
… or SK TU4-…)
The following parameters affect the bus modules.
5.2.1 BUS module standard parameters (P150)
Parameter
{Factory setting}
Setting value / Description / Note Device Supervisor
Parameter
set
P150 Set relays
0 ... 4
{ 0 }
0 = Via bus
1 = Outputs OFF
2 = Output 1 to (DO1)
3 = Output 2 to (DO2)
4 = Outputs 1 and 2 ON
P151 Timeout for external bus
0 ... 32767 ms
{ 0 }
Monitoring function of the relevant active bus technology unit. Following receipt of a valid
telegram, the next one must arrive within the set period. Otherwise the inverter reports an error
and switches off with the error message E010 / E10.3 >Bus Time Out<.
0 = Off: Monitoring is switched off.
Behaviour is identical to parameter (P513) telegram timeout for SK 200E.
NOTE: The time-out time must be set to at least 2x the value of the Profibus cycle time
in parameter (P151).
P152 Factory setting
0 ... 1
{ 0 }
By selecting the appropriate value and confirming it with the ENTER key, the selected
parameter range is entered in the factory setting. Once the setting has been made, the value of
the parameter returns automatically to 0.
0 = No change: Does not change the parameterisation.
1 = Load factory settings: The complete parameterisation of the FI is reset to the factory
setting. All originally parameterised data are lost.
P153 ... [-01]
... [-02]
Minimum system bus cycle
0 ... 250 ms
{ [-01] = 10 }
{ [-02] = 5 }
Reduction of the bus load on the system bus by adjustment of the minimum cycle time (inhibit
time):
… [-01] = SDO Inhibit time … [-02] = PDO inhibit time
P154 ... [-01]
... [-02]
TB-IO access
0 ... 5
{ [-01] = 0 }
{ [-02] = 0 }
SW V1.1R0 and
higher
Direct access to the frequency inverter via 2 digital inputs and/or 2 digital outputs of the bus
module SK xU4-PBR:
… [-01 ] = Access to inputs
Definition of functions:
DigIn1 of the bus module  (P480[-11])
DigIn2 of the bus module  (P480[-12])
… [-02] = Access to outputs
DigOut1 of bus module  (P481[-09])
DigOut2 of bus module  (P481[-10])
Settings:
3 = No effect: The IOs are not evaluated by the FI.
Bits 8 and 9 of the control word can be set or
read out via the PLC. (Section 7.2.1.7, 7.2.1.8)
4 = Broadcast: (This setting can only be used with
(P154[-01])) - All FIs read the inputs, the
settings for (P154[-02]) have no effect.
5 = FI 1: reads and writes the IO
6 = FI 2: reads and writes the IO
7 = FI 3: reads and writes the IO
8 = FI 4: reads and writes the IO
