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 Off
Twin motor [Motor 1A] overload Off

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 sp
eed start condition determines which speed is to be enabled during switch-
on by start condition 1 or 2 at the motor.
