"Motor speed V1−V8" function
By the "Motor speed V1−V8" functions (C0410/1 ... C0410/8), 8 speed values for each
parameter set are provided.
ƒ
The functions are activated via digital signal sources (e. g. digital inputs).
– The brake opens automatically.
– The motor is activated with the frequency (C0011/1 ... C0011/8) that is
parameterised respectively.
– If two speeds are activated at the same time, the higher stage has priority.
Example: If V2 and V5 are activated at the same time, V5 is used.
ƒ
If a "Stop function" is active, the "Motor speed V1−V8" function is inhibited. The
motor control is stopped. The motor is braked to V0 via the deceleration ramp of the
stop function (C0434/1 ... C0434/4).
ƒ
If the "Frequency limitation" function is active, the "Motor speed V1−V8" function is
interrupted. The motor is controlled with the corresponding frequency
(C0440/1 ... C440/4).
The acceleration and deceleration times for V1−V8 can be set individually for each drive
frequency (C0012/1 ... C0012/8 and C0013/1 ... C0013/8). The direction of rotation is
controlled via C0410/9. A second parameter set can be activated via C0410/13.
