3.4.4 Sequence Input Signal Circuit (for Stand-alone Drive)
3
Design the input signals in consideration of the following conditions.
The 12-bit digital reference signals into the Inverter's 1CN connectors and the sequence input signals
D
into 6CN connectors can be 0 V, 24 V, or external common signals. The wiring of terminals varies with
the input method as shown below.
To select the external common method, prepare a 24-V (20 to 26 V) power supply for the input signal.
D
The 1CN common and 6CN common terminals are insulated. Therefore, it is possible to used the com-
D
mon terminals individually.
If a relay contact is used, the minimum contact capacity must be 5 mA at 30 V.
D
There will be a signal delay of approximately 5 ms due to the input filter.
