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 % rated 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 FB L_NSet
.
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 FB L_MPot
.
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 adjusted in C00697
and C00671 for a simple
adjustment of a setpoint encoder.
 Scaling: 16384 ≡ 100 % rated 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 FB L_NSet
.
 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.
