5.Logic of Command Input pulse
5-1 In case of 1-pulse mode
Command pulse is counted at Up-edge of the internal photo coupler outputs. When a motor is in a normal
connection, Command Direction is; CW when the internal photo coupler output is "LOW" and CCW when
the internal photo coupler output is "HIGH". Output of the photo coupler is LOW when the primary LED is
ON. Please note that direction of motor rotation varies also by wire connection.
Timing chart is shown in the following figure.
5-2 In case of 2-pulses mode
Command pulse is counted at Up-edge of photo coupler outputs. Each input becomes stand-by mode at the
high level (photo coupler OFF). A motor rotates CW direction by pulses input to P1, or rotates CCW direction
by the pulses input to P2. Please note that direction of motor rotation varies also by wire connection.
