5.11 Setting basic functions
Procedure with Startdrive
Proceed as follows to check as to whether the fail-safe digital inputs are only used for the
safety functions:
1. Select the screen for the digital inputs.
2. Remove all interconnections of the digital inputs that you use as fail-safe digital input F-DI:
3. You must delete the digital input connections for all CDS if you use the switchover of the
command data sets (CDS).
You can find a description of the CDS switchover in the operating instructions.
You have ensured that the fail-safe digital inputs only control the safety functions in the inverter.
Checking the interconnection of the feedback signal input for the fail-safe digital output
The interconnection of the feedback signal input with a "standard" function may lead to the
drive behaving in unexpected ways.
Preconditions
● You are using the fail-safe digital output of the inverter.
● You use one of the test modes 2 or 3, where the inverter evaluates the status of the
connected actuator via a digital input.
You must check as to whether this digital input is assigned a "standard" function.
Procedure with STARTER
In order to prevent that the feedback signal input of the fail-safe digital output unintentionally
controls the "standard" functions in the inverter, proceed as follows:
1. Select the inputs/outputs in the project navigator of STARTER.
2. Select the screen for the digital inputs.
