Setpoint generator

• For a detailed functional description see FB

L_NSet_1

.

bSetSpeedCcw

BOOL

C00701/5

Change of direction of rotation

• For instance if a motor or gearbox is fixed laterally reversed to a machine part, but

the setpoint selection should still be executed for the positive direction of

rotation.

FALSE Clockwise rotation (Cw)

TRUE Direction of rotation to the left (Ccw)

bJogSpeed1

bJogSpeed2

BOOL

C00701/6

C00701/7

Selection inputs for fixed changeover 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 two selection inputs are binary coded, therefore you can select three fixed

setpoints.

• 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...3

in [%] based on

the reference speed (

C00011

).

• For a detailed functional description see FB

L_NSet_1

.

bRFG_0

BOOL

C00701/12

Ramp function generator: Lead the main setpoint integrator to "0" within the

current Ti times

• For a detailed functional description see FB

L_NSet_1

.

TRUE The current value of the main setpoint integrator is led to "0" within

the Ti time set.

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 FB

L_MPot_1

.

bMPotUp

BOOL

C00701/8

Increasing the speed setpoint

TRUE Approach the upper speed limit value set in

C00800

with the

acceleration time set in

C00802

.

bMPotDown

BOOL

C00701/9

Decreasing the speed setpoint

TRUE Approach the lower speed limit value set In

C00801

with the

deceleration time set in

C00803

.

bMPotInAct

BOOL

C00701/10

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.

bMPotEnable

BOOL

C00701/11

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.
