If you set the parameter
P4
"separate brake / throttle", each of these functions is controlled by a separate potentiometer (voltage, PWM). Brake
function has priority, i.e., if gas is set to a nonzero value and activate the brake, the engine is disconnected and is actively braked proportional-
ly, regardless of the
throttle
position (value). At the moment deactivation of the brake (= neutral, min. position), assumes the function of
throt-
tle
again and the engine is powered by the settings of the
throttle
value (according to the potentiometer, the PWM
…).
Both of these functions, i.e.
throttle
and
brake
are configured in unidirecdtional mode; from the neutral position "back" (if not set to the same
value with neutral) ignored. If you need the engine reversed (direction of rotation reverse) can not be achieved through the neutral gas going to
the "backward" (can not enable bidirectional mode). You must use an external input for changing the direction of rotation. By default, this
function uses the input channel RxD, RS232 TTL, setting in
P54
(but then can not use this type of communication), see next page.
