Transcript
Positioning Operating mode
Under normal conditions, one or more axes are stopped after the module has
reported with a hardware interrupt that the destination (setpoint position) has
been reached.
Note
An axis can always be stopped in an emergency by setting the control bit to
stop.
Moving the axes
via the CPU
To move the axes without positioning, the state of the digital outputs for
forward and backward can be specified by the user program.
Evaluating the
encoder pulses
Asymmetric incremental encoders with two tracks displaced by 90° can be
connected to the CM35.
Direction evaluation
The CM35 determines the counting direction of the signal edges from the
time sequence of the encoder signals.
Track A
Track B
Counterclockwise;
actual value is decremented.
Figure 8-2
Clockwise;
actual value is incremented.
Direction evaluation
Note
The direction of rotation can be inverted with a parameter bit.
