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.
