4.6.6 Motor potentiometer
Changes of the speed set value can be forced by the motor potentiometer depending on
two control bits (Motor potentiometer+ and Motor potentiometer-). The motor potentiom
-
eter writes directly on the ramp function parameter Z110.5– Input 16 bit.
The motor potentiometer is activated via the control parameter Z168.2– Mode.
The motor potentiometer parameter Z168.6– Increment indicates the amount of the in-
crease/decrease of the motor potentiometer output Z168.3–.
Parameter Z168.2– bit 4 sets whether the motor potentiometer function operates edge
sensitive or level sensitive:
m edge sensitive
At increasing edge of Z168.2– bit 1 Motor potentiometer+ or Z168.2– bit 2 Motor
potentiometer-, Z168.6– Increment is added or subtracted once.
m level sensitive
At increasing edge of Z168.2– bit 1 Motor potentiometer+ or Z168.2– bit 2 Motor
potentiometer-, Z168.6– Increment is added or subtracted every 32 ms.
The output of the Motor potentiometer is limited by an upper and a lower limit.
The output of the Motor potentiometer is set to 0 or is synchronized with the ramp function
generator parameter
Z110.5– Input 16 bit depending on parameterization of Z168.2–
Mode bit 3 at activation of the Motor potentiometer.
The output of the motor potentiometer Z168.3– is checked for limits and if necessary ad-
justed in case of Motor potentiometer +/- is activated. If the upper limit is changed so that
the output of the Motor potentiometer is greater than this limit, the output is adjusted
downwards with an activated Motor potentiometer+ function. The modification occurs di
-
rectly without transient.
