Detection Delay Time
F 1 - 0 4 : Operation Selection at
Speed Deviation
Parameters F 1 - 1 0 and F 1 - 1 1 work together to determine when a Speed Deviation
( D E V ) fault will occur. Parameter F 1 - 1 0 determines how far the motor speed has to
differ from the speed reference (set as a percentage of E 1 - 0 4 ), and F 1 - 1 1 determines
how long the speed has to deviate before a fault will occur. Use F 1 - 0 4 to determine
stopping method if a speed deviation fault occurs.
EXAMPLE:
F 1 - 1 0 = 1 0 %, F 1 - 1 1 = 0 . 5 sec, F 1 - 0 4 = 1 , and E 1 - 0 4 (Max
Frequency) = 6 0 Hz. As can be seen below, the motor speed must drop
over 10% below the speed reference for 0.5 seconds before a fault occurs.
10% speed = E 1 - 0 4 x 0.1 = 60 x 0.1 = 6Hz
