TA "Actuating drive speed"
Selection of the main speed setpoint
The main speed setpoint is selected in the Lenze setting via the analog input 1.
Offset and gain of this input signal can be set in C00696
and C00670 for a simple signal
adjustment of a setpoint encoder.
Scaling: 16384 ≡ 100 % reference speed (C00011
)
The main setpoint is transformed to a speed setpoint in the setpoint encoder via a ramp
function generator with linear or S-shaped ramps.
Upstream to the ramp function generator, a blocking speed masking function and a
setpoint MinMax limitation are effective.
For a detailed functional description see the L_NSet
FB.
Motor potentiometer function
Alternatively, the main speed setpoint can be generated via a motor potentiometer
function.
In the Lenze setting, the motor potentiometer function is deactivated.
Activation is possible via C00806
or via the bMPotEnable input.
The behaviour of the motor potentiometer during switch-on of the drive system can be
selected in C00805
.
For a detailed functional description see the L_MPot
FB.
Optional selection of an additional speed setpoint
You can optionally select an additional speed setpoint (e.g. as a correcting signal).
The additional speed setpoint can be linked arithmetically with the main speed
setpoint behind the ramp function generator.
You must set the setpoint arithmetic to "1: NOut = NSet + NAdd" in C00190
in order to
activate the additional speed setpoint.
Offset and gain of this input signal can be set in C00697
and C00671 for a simple signal
adjustment of a setpoint encoder.
Scaling: 16384 ≡ 100 % reference speed (C00011
)
The acceleration and deceleration time for the additional speed setpoint can be set in
C00220
and C00221.
For a detailed functional description see the L_NSet
FB.
Tip!
In the case of a grinding machine, the additional speed setpoint can, for instance,
be used to control a constant circumferential speed while the grinding disk
diameter is reduced.
