NOTE!
In the example above, the Check Back signal was configured for digital input, P208 = 1. The factory
setting is Check Back by motor current, P208 = 0. If P208 = 0, then the digital input I14 becomes free
for the user.
NOTE!
In the Dahlander Starter mode the parameter P401 must be programmed with the low speed nominal
current and P402 must be programmed with the high speed nominal current.
NOTE!
The motor speed can be changed with the motor switched on, after the time defined in P212 has
elapsed.
5.4.7.1 Connection Diagram – Dahlander Starter
The scheme on Figure 5.13 on page 5-22 shows an example of the use of the Control Unit (UC) on the Dahlander
Starting operation mode with drive through digital inputs (P229 or P232 = 0) at 24 Vdc using three wires
(pushbuttons) control logic (P230 = 1).
