Unit Description / Notes
P001 = Reference x P208 / Sync speed x (10)
Where:
Reference = Speed Reference in rpm;
Speed = Motor speed in rpm;
Sync Speed = Motor synchronous speed (120 x P403 / Poles);
Poles = Motor number of poles (120 x P403 / P402).
Example:
Desired indication: 90.0 l/s at 1800 rpm
Motor synchronous speed: 1800 rpm
Programming: P208 = 900, P210 = 1, P207 = l, P216 = /, P217 = s

With the Motor Phase Loss Detector enabled (P209 = 1), E15 happens
when the following conditions occur simultaneously during a minimum
time of 2 seconds:
I. P209 = On;
II. Inverter enabled;
III. Speed reference higher than 3 %;
IV. | I - I
u
or | I
Defines the number of digits after the decimal point of the Speed
0 to 3
Reference (P001) and the Motor Speed indications (P002).

When active, it disables (general disabling, motor runs freely) the inverter
when the speed reference and the actual motor speed are lower than
the value set at P291 (Zero Speed Zone).
The CFW-09 will be enabled again, when one of the conditions defined
by the Parameter P212 is satisfied.
