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 if the controller is inhibited!
• During automatic operation, the internal brake logic is
deactivated and the brake is released (supervisor operation). If a
controller inhibit has been set by the brake control, it will be
deactivated.
• 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.
