■Permissible current of wire
The following table shows permissible currents of wire based on Table 28.1 of UL 508A and Table 40.3 of UL 508C.
The permissible current values listed in this table are for when the number of wires bundled is three or less. When the number
of wires bundled is four to six, the permissible current values are 80 % of the values in the table.
• Permissible currents of copper wire (insulated conductor)
■Rated input current of servo amplifier
The following table shows the 3-phase rated input currents and maximum wire sizes for the MR-J5 series.
