1)
Current [0(4)...20 mA, R
selected with parameter 12.15 AI1 unit selection.
2)
Current [0(4)...20 mA, R
selected with parameter 12.25AI2 unit selection.
3)
Total load capacity of the auxiliary voltage output+24V (X2:10) = 6.0 W (250 mA / 24 V)
- User can use this source for either of theI/O connections (DI1... DI2- RO1 or DI3...DI6 -
RO2~RO3).
4)
The constant speed are set based on the combination of sources as follows:
