X10 24 V AC/DC
Total load capacity of the Auxiliary voltage output +24V (X2:10) is 6.0 W (250 mA / 24 V DC).
Digital inputs DI1...DI5 also support 10...24 V AC.
Terminal sizes (all terminals): 0.14 ... 2.5 mm 2 (26...14 AWG)
Tightening torques: 0.5 ... 0.6 N·m (4.4 ... 5.3 lbf·in)
Wire strip length 7...8 mm (0.3 in)
Notes:
1) Current [0(4)...20 mA, R in = 100 ohm] or voltage [0(2)...10 V, R in >200 kohm]. Change
of setting requires changing the corresponding parameter.
2) Total load capacity of the Auxiliary voltage output +24V (X2:10) is 6.0 W (250 mA / 24 V)
minus the power taken by the option modules installed on the board.
3) In scalar control: See Menu > Primary settings > Start, stop, reference > Constant
speeds / constant frequencies or parameter group 28 Frequency reference chain.
In vector control: See Menu > Primary settings > Start, stop, reference > Constant
speeds / constant frequencies or parameter group 22 Speed reference selection.
