7.2.7 Regarded Safety Related Errors taken Measures

The following table lists safety related errors, possible error causes and the measures or advice for the handling. 

Fault 

Measures, Discussion

Safe position encoder

general fault
Safe encoder stuck at
Safe encoder missing

The safe position encoder is permanently checked by orbit and cross monitoring. 

Motor Temperature from safe stator

No Communication
Communication frozen

Motor temperature is cyclically read.
Checksum and life signal are checked.

Safe Digital Inputs

Inconsistent values
Stuck At

The two input channels are checked for consistency. 

Not detected:

 Stuck at must be detected on the output module, e.g. with test pulse

Safe Digital Outputs

Inconsistency
Stuck at 

The output is permanently feedbacked to detect inconsistencies.
Stuck at high is detected.

Safe Field Bus

Disconnected
Bus Timing
Inconsistent data

Bus cycle time is watched.
Bus cycle time is watched.
Bus is realized as black channel until the safety module. Data are CRC protected.

Safety Parameter Configuration

Parameter out of range
Inconsistency

Wrong encoder type
configured

All parameters are range checked.
Inconsistent parameter combinations are reported as failure. E.g. non-safe encoder
selected in combination with SLS selection over safe digital inputs. 
At startup the electronic data sheet from the stator is read and checked with the configured
type.

Brake Driver

Hardware fault (cannot turn off
brake current)

Dual channel architecture. There are two switches in series to switch off the brake current.
The drive checks periodically if the brake driver can switch off the current. 

STO

Hardware fault, cannot turn off
the power state

Dual channel architecture. The PWM pulse transmission for the power state can be
switched off on high and low side separately. 

The table is continued on the next page.
