Wiring Precautions - Delta C2000 series User Manual

Wiring precautions:

Reserves 5mm and properly install the wire into the terminal; fasten the installation by a
slotted screwdriver. If the wire is stripped, sort the wire before install into the terminal.
Flathead screwdriver: blade width 3.5mm, tip thickness 0.6mm
In the figure above, the factory setting for S1-SCM is short circuit. The factory setting for
+24V-COM is short circuit and SINK mode (NPN); please refer to Chapter 4 Wiring for more
detail.

ON reverse running
OFF deceleration to stop
Refer to parameters 02-01~02-08 to program the
multi-function inputs MI1~MI8.
ON: the activation current is 6.5mA 11Vdc
OFF: leakage current tolerance is 10μA 11Vdc
Regard the pulse voltage as the output monitor

DCM
Max. current: 30mA
Max. voltage: 30Vdc
The AC motor drive releases various monitor
signals, such as drive in operation, frequency
attained and overload indication, via transistor (open
collector).
Max 48Vdc 50mA
Resistive Load:
5A(N.O.)/3A(N.C.) 250VAC
5A(N.O.)/3A(N.C.) 30VDC
Inductive Load (COS 0.4):
2.0A(N.O.)/1.2A(N.C.) 250VAC
2.0A(N.O.)/1.2A(N.C.) 30VDC
It is used to output each monitor signal, such as
drive is in operation, frequency attained or overload
indication.
