Setpoint channel and closed-loop control
7.2 Setpoint channel
Without ramp-function generator tracking
● p1145 = 0
● Drive accelerates to t2, although the setpoint after t1 is smaller than the actual value
With ramp-function generator tracking
● At p1145 > 1 (values between 0 and 1 are not applicable), ramp-function generator
● t1 and t2 are almost identical

tracking is activated when the torque limit is approached. The ramp-function generator
output thereby only exceeds the actual speed value by the deviation value defined in
p1145.
