Programmable inputs (Sequence start)
5.1.2.5
The Softstarter can start up to 3 different motors used
in different applications with different parameter sets.
The parameter set is chosen through input signals to the
Softstarter.
See Figure 5.14, Sequential start of motors using a
Softstarter.
If the Softstarter trips for any reason, and the trip must
stop the motor, all motors are stopped.
When you use sequence start, see Figure 5.15 or Figure
5.16 for the connection.
The start command (terminal 13, 14, 16 and 17) must be
maintained during operation, otherwise a direct stop is
done.
Soft stop can only be done for the motor currently fed by
the Softstarter, by giving a stop command (terminal 14).
