6.2 Rotation direction monitoring

Rotation is controlled via the frequency converter.

(TWU 3-...-HS-I) automatically turns in the right
direction.
• In the version with an external frequency con-
verter (TWU 3-...-HS-ECP), the direction of rota-
tion is shown on the display and can be adjusted
from the menu. See "Setting the operating
parameters".
6.3 Operation and function (TWU 3-...-HS-ECP)
Once all the installation work is complete, the
operating parameters have to be adjusted on the
frequency converter.
These adjustments are only possible in the
"ECP" version. In the "I" version with an internal
frequency converter, no further adjustments are
possible.
