General-purpose Input Signals
The 1S-series Servo Drive provides 8 ports for general-purpose input signals to which you can allocate
function inputs in the Control I/O Connector (CN1). You can also set the logic for input signals that can
be allocated. Note that you cannot allocate more than one function to the same general-purpose input
signal.
3-1-5 Control I/O Connector (CN1) Specifications
on page 3-27 for I/O signal connection and
external signal processing.
General Input 7 (IN7) and 8 (IN8) are high-speed inputs. Use these inputs for functions that require high
precision, such as the latch input.
Precautions for Correct Use
The signal status must be held for at least 125
μ
s for high-speed inputs and at least 2 ms for
other inputs.
