P1061 JOG ramp-down time
Sets ramp-down time (s). This is the time used while jogging or when the function "use jog
ramp times" is activated.
f max
(P1082)
P1080 Min. frequency
Sets minimum motor frequency (Hz) at which the motor will run irrespective of the
frequency setpoint.
The value set here is valid for both clockwise and anti-clockwise rotation.
Note
Under certain conditions (e.g. ramping, current limiting), the inverter can run below the
minimum frequency.
P1082 Max. frequency
Sets maximum motor frequency (Hz) at which the motor will run irrespective of the
frequency setpoint.
The value set here is valid for both clockwise and anti-clockwise rotation.
Notes
There are mechanical limitations to the maximum speed at which a motor can run. In
general, the maximum motor frequency should not exceed 3 x the nominal rating plate
motor frequency.
The maximum frequency can be exceeded if either of the following is active:
