bJogSpeed1

bJogSpeed2

BOOL

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 3 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 the

L_NSet

FB.

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

.

bMPotDown

BOOL

Decreasing the speed setpoint

TRUE Approach the lower speed limit value set In

C00801

with the

deceleration time set in

C00803

.

MCK basic functions
bMBrakeRelease

BOOL

Holding brake control

: Release/apply brake

• In conjunction with the operating mode selected in

C02580

(Lenze setting: "Brake control off").

FALSE Apply brake.

• During automatic operation, the internal brake logic controls the

brake.

TRUE Release brake manually (forced release).

Note!

The brake can also be released when the controller is inhibited!

• During automatic operation, the internal brake logic is

deactivated and the brake is released (supervisor operation). If

the brake control has inhibited the controller, this inhibit is

deactivated again.

• In semi-automatic operation, the brake is released including

feedforward control.

WORD

Direct selection of MCK control words

• E.g. via a master control which has been connected to the fieldbus, too. For this

purpose, the control word inputs can directly be connected to the LP_MciIn or

LP_CanIn fieldbus interface.

• See the "

MCK control word

" chapter for a detailed description of the individual

control bits.
