Setpoints via function "motor potentiometer"
Description
Setpoint selection via two digital signals (UP/DOWN), which are controlled by means of,
for instance, simple pushbuttons.
The output frequency in changed via the acceleration and deceleration times set for the
main setpoint (C0012/C0013) or for the additional setpoint (C0220/C0221).

Starting value: output
frequency which is approached
with Tir (C0012) after mains
connection when the motor
potentiometer is activated:
– "Power off" = actual value
when the power is switched
off
– "C0010": minimum output
frequency from C0010. The
setpoint must have
exceeded C0010 previously.
– "0" = output frequency of 0

motor potentiometer along
the QSP ramp (C0105)

1. Link to external signal sources in C04110/7 UP and in C0410/8 DOWN.
)
Note!
In addition to the free configuration in C0410 you can also use the fixed
assignment in C0007 to link the function to digital inputs.
2. In C0412, assign the desired setpoint to the "Motor potentiometer" signal source
(C0412/x = 3). (
