8.4.11 Motor fault
Output motor fault is "On" in the case of a fault when the motor no longer is able
to transport the medium. It is used to forward the fault information to another
aggregate.
The following table shows the output motor fault state for the corresponding
causes of fault:
Motor type
Fault
"Motor fault " state
1, 2-speed motor
or
twin motor
[Mot 1] precom no checkb signal
On
1
or
2-speed motor
[Motor 1] no flow
On
1
or
2-speed motor
[Motor 1] overload
On
Twin motor
[Motor 1] fault
On
Twin motor
[Motor 1A] no flow
Off
Twin motor
[Motor 1B] no flow
Off
Twin motor
[Motor 1A] overload

8.4.12 Start and stop conditions
You can configure two inputs as start and stop conditions for each motor block.

Start condition 1
---, N.X1, N.X2,... (digital and analog inputs).
Start condition 2
---, N.X1, N.X2,... (digital and analog inputs).
Stop condition 1
---, N.X1, N.X2,... (digital and analog inputs).
Stop condition 2
---, N.X1, N.X2,... (digital and analog inputs).
Stop conditions take priority over start conditions (see Section 8.4.19).
The speed start condition determines which speed is to be enabled during switch-
on by start condition 1 or 2 at the motor.
