Configuring an encoder with Startdrive
When configuring the encoder, you must select an encoder type that has the best possible fit
to the real encoder.
Precondition
You have started the commissioning Wizard of the inverter.
Procedure
1. In the "Encoder" commissioning step, select the multiturn encoder with SSI interface.
2. Complete the commissioning Wizard.
