[ 2 ] Current in each loom operation state
NOTE:
The loom with an electronic shedding motion requires the additional current besides the
above current to operate the electronic shedding motor. The additionally required current can be
roughly calculated by the formula below:
•
Shedding motion for 8 frames
(A)
•
Shedding motion for 10 frames
(A)
•
Shedding motion for 12 frames
(A)
•
Shedding motion for 16 frames
