5.4.6.1 Connection Diagram – Star-Delta Starter
The scheme on Figure 5.10 on page 5-20 shows an example of the use of the Control Unit (UC) on the Star-
Delta Starting operation mode with drive through digital inputs (P229 or P232 = 0) at 24 Vdc using three wires
(pushbuttons) control logic (P230 = 1) and measurement of delta current.

(P230=1) and measurement of delta current
ATTENTION!
If the Current Measurement Unit (UMC) is inserted in the delta connection (typical connection), the
motor rated current value (P401) must be adjusted for

The modifications of the scheme for drive through the digital inputs (P229 or P232 = 0) at 24 Vdc, using two wires
(switch) control logic (P230 = 0) is shown on
