Remedy
permissible to reset the safety functions as the safety functions are currently
enabled.
Remedy with operator panel:
p0010 = 30 Parameter reset
p9761 = ... Enter password for the safety functions.
p0970 = 5 Reset start safety parameter.
The inverter sets p0970 = 5 once it has reset the pa-
rameter.
Then reset the inverter to the factory setting again.
Switch off the inverter and switch on again, upgrade the firmware or contact
technical support.
Set F-DI to a logical 0 signal.
This message is withdrawn after the Safety commissioning has ended.
After the next time that the "STO" function is deselected, the message is
withdrawn and the monitoring time is reset
Check the connection to the signal source for interrupts.
Check the level of the signal supplied.
The input current measured by the analog input can be read out in r0752.
Check that the sensor is connected correctly.
Check the following:
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
Reduce the motor load.
Check ambient temperature.
Check sensor's wiring and connection.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
Make sure that the sensor is connected correctly.
Check the parameterization (p0601).
Check the adapted parameter values and if required correct.
