Time of the forced dormant error detection
In the case of warning A01699 , you must initiate a forced dormant error detection at the next
opportunity. These alarms do not affect the operation of your machine.
● Switch off the motor.
● Select function STO or switch off the inverter supply voltage temporarily and on again.
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).
