14.1.83 L_MPot_1
This FB replaces a hardware motor potentiometer and can be used as an alternative
setpoint source which is controlled via two inputs.
The signal is output via a ramp function generator with linear ramps.
The acceleration and deceleration times are set via parameters.
Constant ramping even with speed limit values changed online.
The motor potentiometer function can be switched on/off online.

Identifier
Data type
Information/possible settings
bEnable
BOOL
Switch over motor potentiometer function
bEnable input and C00806
code are ORed.
TRUE Motor potentiometer function is active, setpoint can be changed via
bUp and bDown.
• With switching to TRUE, the value applied to nIn_a is
automatically transferred to the motor potentiometer.
FALSE The value applied to nIn_a is output at nOut_a.
nln_a
INT
When bEnable = FALSE, the analog input signal nIn_ is switched to the nOut_a
output.
bUp
BOOL
Approaching of the upper speed limit value set in C00800.
TRUE The nOut_a output signal runs to its upper limit value (nHighLimit).
•If the bDown input is simultaneously set to TRUE, the nOut_a
output signal is not changed.
bDown
BOOL
Approaching of the lower speed limit value set in C00801.
TRUE The nOut_a output signal runs to its lower limit value (nLowLimit).
•If the bUp input is simultaneously set to TRUE, the nOut_a output
signal is not changed.
bInAct
BOOL
Deactivate motor potentiometer function
• This input has the highest priority.
• When the motor potentiometer is deactivated, the nOut_a output signal follows
the function set with code C00804
.
TRUE Motor potentiometer function is deactivated.
