safety card
DANGER
The MOVISAFE
®
CS..A safety card has an error and automatically restarts in the fol-
lowing cases:
- The DC-24-V supply voltage was switched off and back on.
- The safety card was in the standby state.
- Several inverter faults were acknowledged.
Severe or fatal injuries
•
To prevent automatic restart in the aforementioned cases, the parameter
Error
status after startup
(8703.240) must be parameterized to "Start inhibit". Start in-
hibit must be acknowledged.
12.4.1
Fault classes
The occurring safety card errors are divided into 5 different error classes. Depending
on the fault class, the response described in the following table is carried out.
Fault class
Response
Message.
Entry in fault memory, no further response.
Warning.
Entry in fault memory, no further response.
Output fault, input fault, encoder
fault.
Entry in fault memory and safe state of digital in-
puts and outputs as applicable.
System error.
Entry in fault memory and safe state of digital in-
puts and outputs.
Critical fault.
Entry in fault memory and safe state of digital in-
puts and outputs. No safe communication.
Message
No error response is carried out in the case of a message. An entry is made in the
fault memory. In addition, the corresponding error code is transferred.
Warning
No error response is carried out in the case of a warning. An entry is made in the fault
memory. In addition, the corresponding error code is transferred.
A warning is information, e.g. about a fault in the encoder system, which has no effect
with regard to safety technology at the time of occurrence, but which can represent a
fault at a later time.
Output fault, input fault, encoder fault
Output fault
If the safety card detects an error at a safe digital output, all safe digital outputs are
switched to the safe state. In addition, the drive safety function STO is activated and
the safety card is set to the safe state. In the FS protocol, the bits of the outputs F-
DO0 and F-DO1 are set to "0" and the bits for the drive safety function STO and the
error are set to "1".
In addition, the corresponding error code is transferred for the output error that oc-
curred.
