Control signals of the motor potentiometer
In addition to the digital signals MPOT1-UP and MPOT1-DOWN another digital input exists
(MPOT1-INACT). The input MPOT1-INACT is used to activate or deactivate the motor potentiometer
function. Logic 1 at this input deactivates the motor potentiometer function. The input
MPOT1-INACT has priority over the inputs MPOT1-UP and MPOT1-DOWN.
When the motor potentiometer is deactivated, the motor potentiometer output (MPOT1-OUT)
follows the function set under C0264. The following functions can be set under C0264:
C0264 = Meaning
0 No further action; the output MPOT1-OUT keeps its value
1 The motor potentiometer returns to 0 % with the corresponding deceleration time
2 The motor potentiometer approaches the lower limit value with the corresponding deceleration time (C0261)
3 The motor potentiometer immediately changes its output to 0%.
4 The motor potentiometer immediately changes its output to the lower limit value (C0261)
5 The motor potentiometer approaches the upper limit value with the corresponding acceleration time (C0260)
If the motor potentiometer is activated (input MPOT1-INACT = 0), the subsequent function depends
on
•
the current output signal,
•
the set limit values of the MPOT,
•
the control signals UP and DOWN.
If the output value is out of the set limits, the MPOT approaches the next limit with the set T
This function is independent of the control inputs MPOT1-UP and MPOT1-DOWN
If the output value is within the set limits, the output follows the selected control function UP, DOWN
or no action.
