The system could not be initialized. Implausible feedback has been received from
the SINAMICS DCPs
Check the configuration of the SINAMICS DCPs and ensure that these are not
sending the feedback "running" during PLC startup.
Battery current limit < min start current
Fault
Storage battery
Shutdown routine 2
Acknowledge
Precharging of the DC link could not be performed, as the battery current is too
low for startup
Check the battery and the battery current limit transferred from the battery
Start inhibited: Cool down active Unit 5

Shutdown routine 2
Acknowledge
• Started too often in succession
• Precharge resistor of SINAMICS DCP unit 5 is in the cooldown phase when the
start command is issued
In order to avoid hardware damage, wait until the precharge resistors have
cooled down before startup
Start inhibited: Cool down active Unit 6
