Figure 2-11 Ramp function generator tracking

Without ramp function generator tracking

p1145 = 0

Drive accelerates until t2 although setpoint < actual value

With ramp function generator tracking

At p1145 > 1 (values between 0 and 1 are not applicable), ramp function generator tracking is activated when the torque limit is approached. The ramp function generator output thereby only exceeds the actual speed value by a deviation value that can be defined in p1145.

t1 and t2 almost identical
