CSD7 Servo Drive (EtherCAT)
Sequence I/O Signal
What is Sequence I/O Signal ?
To provide the optimum performance that is suitable for user’s
equipment, 20 pin connector of I/O is used to allow the drive can
input/output signals that have various functions.
Input provides 11 functions and you can freely allocate input signal
of each function with 4 pins such as pin No. 5, 6, 7 and 8 of I/O.
Output provides 12 functions and you can freely allocate output
signal of each function with three pairs of pins such as pin No.
(15,16), (17,18) and (19,20) of I/O.
Sequence I/O signal means the I/O signal of various functions that
are required for the sequence control of the servo drive by the host
controller.
Sequence I/O signal is not to process input or output signal with the
fixed pin of I/O, but to select the function that the user requires in
terms of circuit design of host controller and to directly allocate the
selected functions to the designated pin.
Therefore, the host controller can do the sequential control that fits
to the equipment to operate servo drive.
