Setpoint generator
• For a detailed functional description see FB
.
bSetSpeedCcw
BOOL
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
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
in [%] based on
the reference speed (
• For a detailed functional description see FB
bRFG_0
BOOL
Ramp function generator: Lead the main setpoint integrator to "0" within the
current Ti times
• For a detailed functional description see FB
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
or via the bMPotEnable input.
• The behaviour of the motor potentiometer during switch-on of the drive system can be selected in
.
• For a detailed functional description see FB
bMPotUp
BOOL
Increasing the speed setpoint
TRUE Approach the upper speed limit value set in
with the
acceleration time set in
.
bMPotDown
BOOL
Decreasing the speed setpoint
TRUE Approach the lower speed limit value set In
with the
deceleration time set in
.
bMPotInAct
BOOL
Activating the inactive function
TRUE The speed setpoint behaves according to the inactive function set in
• In the Lenze setting, the speed setpoint is maintained.
bMPotEnable
BOOL
Activating the motor potentiometer function
• This input and
are OR'd.
TRUE The motor potentiometer function is active; the speed setpoint can
be changed via the bMPotUp and bMPotDown control inputs.
