3-1-2. Sequential chart of control signals
In order to ensure the reliability of the system response, please take the following
advices.
The signal high voltage is 24V; low voltage is less than 0.5V.
The ENA (enable) signal should turn to high-level at least 3s before DIR
(direction) signal.
Ensure the falling edge of the DIR (direction) signal is built at least 5μs before
PUL (pulse) signal.
The width of pulse should be more than 1.2μs
The duration of the pulse low-voltage should be more than 1.2μs
The sequential chart is shown as below:
3-1-3. Input circuit
The common positive connection of input circuit is shown as below:
Note:
All the input signals go through the photoelectric isolation. To ensure the well
conducting of inside high-speed optical coupler, keep the control signal current
