Control example for SIMATIC S7 with MOVITRAC

The drive inverter is controlled using SIMATIC S7 in accordance with the selected pro-
cess data configuration either directly using load and transfer commands or by means
of special system functions SFC 14 DPRD_DAT and SFC15 DPWR_DAT.
In principle, S7 data lengths of 3 bytes or more than 4 bytes must be transmitted using
system functions SFC14 and SFC15.

SBus timeout

If one or more drive inverters on the SBus can no longer be addressed by the DFE32B,
the gateway displays error code F11 System error in status word 1 of the corresponding
inverter. The H1 LED (system error) lights up, and the error is also displayed via the di-
agnostics interface. It is necessary to set the SBus timeout interval (P815) of the
MOVITRAC
resets itself in the gateway, which means the current process data are exchanged im-
mediately after communication is restarted.
6.5.3

Unit errors

The gateways detect a series of errors during the self test and respond by locking them-
selves. For the exact error responses and according measures please refer to the error
list (→ "Error list in gateway operation"). A hardware defect causes error F111 system
errorto be displayed on the fieldbus process input data for status words 1 of all drive in-
verters. The H1 LED (system error) at the DFE is lit. The exact error code of the gateway
status can be displayed via the diagnostics interface with MOVITOOLS
(Tool "Status").

Fieldbus timeout response of the DFE32B in gateway operation

You can set how the gateway should respond in case of timeout using the P831 Fieldbus
timeout response parameter.

The drives on the subordinate SBus continue with the last setpoint value.
These drives cannot be controlled when the PROFIBUS communication is
interrupted.
The rapid stop is activated for all drives that have a process data configuration
with control word 1 or 2 when a PROFINET timeout is detected. For this, the
gateway sets the bits 0 to 2 of the control word to 0.
The drives are stopped via the rapid stop ramp.
