nAuxSetValue_a
INT
Additional speed setpoint
• 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
order to activate the additional speed setpoint.
• Offset and gain of this input signal can be set in
and
for a simple
signal adjustment of a setpoint encoder.
• Scaling: 16384
≡
100 % reference speed (
)
• The acceleration and deceleration time for the additional speed setpoint can be
.
• For a detailed functional description see the
FB.

BOOL
Inputs for overriding fixed setpoints (JOG setpoints) for the main setpoint
• A fixed setpoint for the setpoint generator can be activated instead of the main
setpoint via these selection inputs.
• The four selection inputs are binary coded, therefore 15 fixed setpoints can be
selected.
• In the case of binary coded selection "0" (all inputs = FALSE or not assigned), main
setpoint
nMainSetValue_a
is active.
• The selection of the fixed setpoints is carried out in
in [%] based

BOOL
Selection inputs for alternative acceleration/deceleration times for the main
setpoint
• The four selection inputs are binary coded, therefore 15 alternative
acceleration/deceleration times can be selected.
• For main setpoint
nMainSetValue_a
, the set acceleration time (
deceleration time (
) are active in the case of the binary coded selection "0"
(all inputs = FALSE or not assigned).
• Alternative acceleration times are selected in
.
• The selection of the alternative deceleration times is carried out in
.

BOOL
Motor potentiometer
Alternatively to the input signal
nMainSetValue_a
, the main setpoint can also be generated by a motor
potentiometer function.
• In the Lenze setting, the motor potentiometer function is deactivated.
• Activation is possible via
bMPotEnable
input.
• The behaviour of the motor potentiometer during switch-on of the drive system can be selected in
• For a detailed functional description see the
FB.
bMPotEnable
BOOL
Activating the motor potentiometer function
• This input and
are OR'd.
TRUE The motor potentiometer function is active; the speed setpoint can
be changed via the
bMPotUp
and
bMPotDown
control inputs.
bMPotUp
BOOL
Increasing the speed setpoint
TRUE Approach the upper speed limit value set in
with the
bMPotInAct
BOOL
Activating the inactive function
TRUE The speed setpoint behaves according to the inactive function set in
.
• In the Lenze setting, the speed setpoint is maintained.
bMPotDown
BOOL
Decreasing the speed setpoint
TRUE Approach the lower speed limit value set In
with the
deceleration time set in
