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 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.

bJogSpeed2
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 C00039/1...15
in [%] based
on the reference speed (C00011
).
• For a detailed functional description see the L_NSet
FB.

BOOL
bJogRamp1
bJogRamp2
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 (C00012
) and
deceleration time (C00013
) are active in the case of the binary coded selection "0"
(all inputs = FALSE or not assigned).
• Alternative acceleration times are selected in C00101/1...15
.
• The selection of the alternative deceleration times is carried out in C00103/1...15
.
• For a detailed functional description see the L_NSet
FB.

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 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.
bMPotEnable
BOOL
Activating the motor potentiometer function
•This input and C00806
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 C00800
with the
acceleration time set in C00802
.
bMPotInAct
BOOL
Activating the inactive function
TRUE The speed setpoint behaves according to the inactive function set in
C00804
.
• In the Lenze setting, the speed setpoint is maintained.
bMPotDown
BOOL
Decreasing the speed setpoint
TRUE Approach the lower speed limit value set In C00801
with the
deceleration time set in C00803
.
