9.1.2 L_MPot
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.
 The potentiometer function is selected via the Function parameter.

Identifier/data type Information/possible settings
bEnable
C701/11
BOOL
Change-over of motor potentiometer function
Input bEnable and code C806 bEnableInternal are ORed.
True The motor potentiometer function is active, setpoint can be changed
via bUp and bDown.
•With a change-over 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.
nIn_a
C700/1
INT
When bEnable = FALSE, the analog input signal nIn_ is switched to the nOut_a
output.
bUp
C701/8
BOOL
Increase output signal
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
C701/9
BOOL
Reduce output signal
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
C701/10
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 Function.
True Motor potentiometer function is deactivated.
