With cn.10 it is possible to set the reset conditions for the PID-Controller. Thus simple
speed regulations can be realized for both directions of rotation.

For speed regulations adjust the value „2", with that the I-component of the controller
is reset at LS or nOP. The value „1" serves mainly for the start-up, to reset the controller
manually.
The whole controller, the I-component as well as the controller fade-in can be reset via
a digital input. When resetting the masking the fade-in time is valid. For that purpose
the decimal value of the corresponding inputs according to the table below has to be
entered.

This block converts the percental controller output value into a frequency. The
adjustment of cn.14 determines which frequency is output at 100 % controller output
value. A frequency from 0.0...400.0 Hz (dep. on ud.2) can be adjusted. At cS.0 bit
0...1 = 1 the output value added with the ramp output frequency (ru.2) forms the
output frequency (ru.3).
