Part 1 Specification
[4] Output control signals (Axis 1 = Direct numerical specification mode)
An example of control signals of axis (1) is explained.
The configuration of the control signal register of axis (1) is shown below.
The method of use is the same as in [3], except for the DIR and PUSH.
The DIR and PUSH signals are used as a set when performing push operation in the direct numerical specification
mode.
x PUSH signal: The push mode is effective when this signal is “1.”
x DIR signal: This signal specifies the push direction.
“0” = Home return direction “1” = Opposite home return direction
In other conditions, the push speed corresponds to the specification of parameter No. 34, while the maximum push
amount corresponds to the specified positioning band.
A query in the push operation mode is described below.
