Setpoint generator

• For a detailed functional description see FB

L_NSet

.

bSetSpeedCcw

BOOL

C701/5

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 rotati-

on.

FALSE Clockwise rotation (Cw)

TRUE Counter-clockwise rotation (Ccw)

bJogSpeed1

bJogSpeed2

BOOL

C701/6

C701/7

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 fixed setpoints are selected in

C039/1...3

in [%] based on the reference speed

(

C011

).

• For a detailed functional description see FB

L_NSet

.

bRFG_0

BOOL

C701/12

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

rent Ti times

• For a detailed functional description see FB

L_NSet

.

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 potentiome-

ter function.

• In the Lenze setting, the motor potentiometer function is deactivated.

• Activation is possible via

C806

or via the bMPotEnable input.

• The behaviour of the motor potentiometer during switch-on of the drive system can be selected in

C805

.

• For a detailed functional description see FB

L_MPot

.

bMPotUp

BOOL

C701/8

Increasing the speed setpoint

TRUE Approach the upper speed value set in

C800

with the acceleration

time set in

C802

.

bMPotDown

BOOL

C701/9

Decreasing the speed setpoint

TRUE Approach the lower speed limit value set in

C801

with the decelera-

tion time set in

C803

.

bMPotInAct

BOOL

C701/10

Activating the inactive function

TRUE The speed setpoint behaves according to the inactive function set in

C804

.

• In the Lenze setting, the speed setpoint is maintained.

bMPotEnable

BOOL

C701/11

Activating the motor potentiometer function

• This input and

C806

are OR'd.

TRUE The motor potentiometer function is active; the speed setpoint can

be changed via the bMPotUp and bMPotDown control inputs.
