Two-wire control, method 3
Function description
This control method uses two control commands as permanent signals.
Like method 2, CW and CCW rotation can be started/stopped by one control command
each. In contrast to method 2, however, the control commands can be switched at any time
regardless of the setpoint, output frequency, and direction of rotation. The motor does not
have to coast to 0 Hz either before a control command is executed.
