CO: Selected frequency
setpoint [Hz]
- - - - - Float 3
Displays selected frequency setpoint. Following frequency setpoints are displayed:
• r1078 Total frequency setpoint
• P1058 JOG frequency right
• P1059 JOG frequency left
Dependency:
P1055 (BI: Enable JOG right) or P1056 (BI: Enable JOG left) define command source of JOG right or JOG
left respectively.
Note:
P1055 = 0 and P1056 = 0 ==> Total frequency setpoint is selected.

1
Sets minimum motor frequency at which motor will run irrespective of frequency setpoint. The minimum
frequency P1080 represents a masking frequency of 0 Hz for all frequency target value sources e.g. ana-
log input, MOP, FF, USS with the exception of the JOG target value source (analogous to P1091). Thus
the frequency band +/-P1080 is run through in optimum time by means of the acceleration/deceleration
ramps. Dwelling in the frequency band is not possible. Furthermore, an overshoot of the actual frequency
f_act upper minimum frequency P1080 is output by the signal function |f_act| > f_min.
Note:
Value set here is valid both for clockwise and for counterclockwise rotation.
Under certain conditions (e.g. ramping, current limiting), motor can run below minimum frequency.
