I/O Signal Allocations
Functions are allocated to the pins on the I/O signal connector (CN1) in advance. You can change the
allocations and the polarity for some of the connector pins. Function allocations and polarity settings are
made with parameters.
7.8.1
Input Signal Allocations
Allocation Description
The I/O signal connector (CN1) on the Drive provides five pins (points) for allocating the input signals,
corresponding to the sub-parameters of Pn509 and Pn510, as is shown in Table 7-1.
Table 7-1
Input signals allocated
Parameter
Pin
Meaning
Pn509.0
CN1-14
Allocated the input signal to CN1-14.
Pn509.1
CN1-15
Allocated the input signal to CN1-15.
Pn509.2
CN1-16
Allocated the input signal to CN1-16.
Pn509.3
CN1-17
Allocated the input signal to CN1-17.
Pn510.0
CN1-18
Allocated the input signal to CN1-18.
IMPORTANT
If you allocate two or more signals to the same input circuit, a logical OR
of the inputs will be used and all of the allocated signals will operate
accordingly. This may result in unexpected operation.
Since the pins have priority, only the highest priority pin is in effect if a
signal is repeatedly allocated to multiple pin. The priority of the pins is
arranged from high to low as follows:
CN1-18
→
CN1-17
→
CN1-16
→
CN1-15
→
CN1-14
Input Signals
Table 7-2 lists the input signals that can be allocated and their corresponding values. Set the sub-
parameters of Pn509 and Pn510 to use the following values, which means that they are allocated to the
corresponding pins.
