Communication phase 3 signifies that the drive is in restricted parameter-setting mode.
In this mode - as in parameter-setting mode (phase 2) - you can write to many param-
eters which are no longer editable in communication phase 4 (operation mode). No
communication parameters can be written in phase 3. During communication phase 3
the green LED H5 on the drive unit cyclically displays the flash code set out in the follow-
ing table.

3.5 Communication phase 4
Before the system can switch to communication phase 4, command S-0-0128 - “Prepare
switch to communication phase 4” - must be executed. During this preparatory phase
the drive checks criteria including the validity of the parameters required for communica-
tion phase 4. When the prepare-to-switch command has been successfully executed,
the drive is switched to communication phase 4 by the master. During communication
phase 4 the green LED H5 on the drive unit cyclically displays the flash code set out in
the following table. The drive can only be enabled via the control word in communica-
tion phase 4.
