EDSVS9332S−EXT EN 2.0
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%.
(Important for EMERGENCY−OFF function)
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
l the current output signal,
l the set limit values of the MPOT,
l 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
i
times.
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.

Initialisation
This function is used to store the output value of the MPOT non−volatilely in the internal memory of
the device, when the mains is switched off. The value is saved automatically if this function was
selected via the code. When the mains is switched on, the value is reloaded into the MPOT.
C0265 can be used to activate other initialisation functions (see code table).
When the initialisation is completed, the MPOT follows the applied control function.
