7-1 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.
Refer to 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 μs for high-speed inputs and at least 2 ms for
other inputs.
