Waiting for Defaulting Parameters:
When ID (S1, S2) is set to 0xFF, the drive starts up in a special mode and the Error

will be set to their default value. To leave this state, power down the drive and
change the ID. Also see in the Usermanual_LinMot-Talk under chapter trouble
shooting.

Defaulting Parameters Done:
When the parameters have set to their default values (initiated via S1/S2 on power
up) the Warn and En LEDs blink together at 2 Hz. To leave this state, power down
the drive. Also see in the Usermanual_LinMot-Talk under chapter trouble shooting.
Bootstrap
If also both RT LEDs are on, the drive is in the bootstrap mode. Set S5 to off.
