9 Fault messages
When an error occurs, the following three steps must be performed:

Error analysis:
If the error text displayed by MSC is not sufficiently self-
explaining, additional error causes are listed in the online help of MSC or in section
15.6
2.
Error elimination:
Eliminate the cause of the error in compliance with the safety
instructions (section 2.4
3.
Error acknowledgement:
Clear the error by clicking the button
Clear
in the MSC
error window. Alternatively, the error can also be acknowledged via a bus system.
Risk of damage to property
Clearing an error via MSC can lead to a sudden restart if the superordinate control
system or an external logic system enables the power automatically.
If the drive is checked in order to find the cause of an error, suitable interrupting devices
(STO inputs, deactivation of the power supply) must be present and activated.
The following precautionary measures can be applied:
l
Disconnection of the mains power supply connector
l
Activation of the STO safety function
l
Deactivation of the bus system via MSC or by disconnecting the bus connector
l
Interruption of the connection to the motor
l
Disconnection of the shaft connection (coupling) between the motor and output
shaft in order to test the motor without damaging the machine.
