P24
Power supply
terminal for
input signal
24 VDC internal power
supply terminal for
contact input. Common
for source logic input.
By supplying external 24
VDC to this terminal, it is
possible to operate only
the control board and
parameters can be
read/written. When an
external power supply is
connected, be sure to
connect a reverse current
prevention diode.
Maximum allowable current:
100 mA

Source logic: short-circuit
to [L] terminal
When driving the contact
input with an external
power supply, remove the
short-circuit wire. See
"5.4.3 Switching
Sink/Source Logic and
Connecting External
Power Supply/
Programmable Controller"
for more information.

Each terminal function
can be selected by
parameter setting for
each terminal.
Both sink and source
logic are supported. See

[PLA]
Pulse input A
Pulse input terminal.
5 to 24 VDC can be input.
(Note that the internal
circuit is different from
[PLB] of input terminal 7.)
Input pulse:
Minimum 0.3 Hz to maximum
32 kHz
[PLA] - [L] voltage:
ON voltage: Min. 4 VDC
OFF voltage: Max. 1 VDC
Maximum allowable voltage:
27 VDC
Internal resistance: 10 kΩ

[PLB]
Pulse input B
B-phase pulse input or
direction command for
single-phase pulse input.
Set "Pulse input B [PLB]"
to "Input terminal 7
function selection
[C007]" to be enabled.
(Internal circuit is
different from the [PLA]
input terminal. Be careful
when wiring.)
Input pulse:
Minimum 0.3 Hz to maximum
32 kHz
