[ 2 ] Current in the loom operation state (Excluding the jacguard)
(Towel weaving machine)
•
In addition to the above, a current of
(A) flows through the machine
excluding the power consumption of the motor.
(Label weaving machine with separate inverter)
•
In addition to the above, a current of
(A) flows through the machine
excluding the power consumption of the motor.
[ 3 ] Motor rated current In
Towel weaving machine
[ 4 ] Cable selection
Select the cable according to steps [1], [2] and [3].
(1) Obtain the current flowing in cable
①
between the circuit breaker on the switchboard and the inverter.
(Excluding the jacquard.)
Current at the start of the machine = Motor rated current x Approx. 7
Current during operation =
+ Motor rated current
(Towel weaving machine)
Current during operation =
+ Motor rated current
(Label weaving machine with separate inverter)
(2) Select the cable
①
so that:
- the total voltage drop caused by line voltage fluctuation and by the cable becomes within 10% at the
starting current and
- the current flowing during operation becomes within the allowable current value of the cable.
Out of the above cables, you should select the cable of a larger diameter.
