Execute the forced dormant error detection
If the inverter outputs alarm A01699 or A01697, you must initiate forced dormant error
detection at the next opportunity.
These alarms do not affect the operation of your machine. Before the forced dormant error
detection you must stop the drive.
Table 2- 6
Extended Safety
You define the signal with which the inverter tests
its circuits for speed monitoring.
If you select the forced dormant error detection,
the inverter will check the circuits of both
Extended Safety and Basic Safety.
Examples for the times when forced dormant error detection is performed
● When the drives are at a standstill after the system has been switched on.
● When the protective door is opened.
● At defined intervals (e.g. every 8 hours).
● In automatic mode (time and event dependent).

Initiating the forced dormant error detection
2.11 Forced dormant error detection (test stop)
Basic Safety
The inverter checks its circuits used to switch off
the torque if one of the following conditions
exists:
After the power supply has been switched on
•
(power on reset).
Each time after the STO.function has been
•
selected.
In the event of forced dormant error detection
