Communcation Parameters
The following communication paramters are relevant
in case of external drives control.
Cmd Location (2.02)
Purpose: Determines whether Drive is externally con-
trolled via conventional I/O or serial interface.
Value:
0 Macro depend
1 Terminals (X1...X5 on SDCS-CON-3)
2 Bus - The serial interface for external control is
specified in Parameter
Modul Type (8.01)
(Fieldbus, RS232-Port or Panel-Port)
3 Key - Automatic switch over between bus and
terminals
Comm Fault Time (2.08)
Purpose: For supervision of communication on the
serial interface which is used for external drive control
(defined in Paramter
Modul Type (8.01) .
Value:
0.01...10 sec
Determines the maximum allowed down time for
communication in seconds. If no messages are
received within this time, an error message will be
issued and the drive will behave according to
Parameter
Comm Fault Mode (2.07) ;
0.00s = ignore error, Continue drive operation.
Comm Fault Mode (2.07)
Purpose: Defines how the drive will behave in case of
communication error.
Value:
0 Brake with deceleration ramp (Parameter
5.10) , then switch off drive and error message
1 Brake with torque = torque limit (Parameter
3.07, 3.08) , then switch off of drive and error
message.
2 Immediate switch off drive and error message
