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.
Inputs
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.
