Digital inputs DI1…DI5 also support 10 to 24 V AC
Terminal sizes: 0.14…2.5 mm

(all terminals)
Tightening torques: 0.5…0.6 N·m (0.4 lbf·ft)
Notes:
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.
1)
Total load capacity of the Auxiliary voltage 24V (X2:10) is 6.0 W (250 mA / 24 V)
minus the power taken by the option modules installed on the board. 2)
In scalar control: See Menu > Primary settings > Start, stop, reference > Constant
speeds / constant frequencies or parameter group 28 Frequency reference chain.
3)
In vector control: See Menu > Primary settings > Start, stop, reference > Constant
speeds / constant frequencies or parameter group 22 Speed reference selection.
Connected with jumpers at the factory. 4)
Use shielded twisted-pair cables for digital signals. 5)
Ground the outer shield of the cables 360 degrees at the cabinet entry. 6)
With E205 in frames R10 and R11, digital input DI6 is reserved for internal overtem-
perature supervison of the cabinet. See section
DI6 for internal overtemperature supervision
with E205 in frames R10 and R11 (page 142)
7)
WARNING! Connect external AC power supply (24 V AC) to control unit connectors
40 and 41. If you connect it to connector AGND, DGND or SGND, the power supply
or the control unit can get damaged.

DI6 for internal overtemperature supervision with E205 in frames
R10 and R11
With E205, digital input DI6 is used by default for the internal overtemperature
supervision of the cabinet in frames R10 and R11. The I/O connection is shown below.

*) Internal overtemperature supervision of the cabinet is connected between DI6 and
+24V auxiliary voltage supply.
If DI6 is to be used for another purpose, change the overtemperature supervision wiring
from DI6 to another free digital input either on the control unit or on the CMOD-01
