2.4.44.2 Deactivation of the motor potentiometer
You can deactivate the function of the motor potentiometer using the input MPOT1−INACT.
l The motor potentiometer function is deactivated with MPOT1−INACT = HIGH.
l The input MPOT1−INACT has priority over the inputs MPOT1−UP and MPOT1−DOWN.
l When the function is deactivated, the output signal at MPOT1−OUT follows the function set
under C0264. You can set the following functions 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 Ti time
2 The motor potentiometer approaches its lower limit (C0261) with the corresponding deceleration time
3 The motor potentiometer immediately changes its output to 0 % (important for emergency stop function)
4 The motor potentiometer immediately changes its output to the lower limit (C02619
5 The motor potentiometer approaches its upper limit (C0260) with the corresponding Ti time
If the deactivation of the motor potentiometer is cancelled with MPOT1−INACT = LOW, the
subsequent function depends on
l the momentary output signal,
l the set limits (C0261: lower limit, C0260: upper limit),
l the control signals MPOT1−UP and MPOT1−DOWN.
If the output value is out of the limits, the output signal approaches the next limit with the suitable T
i
time (C0262: acceleration time T
ir
, C0263: deceleration time T
if
). This function is independent of the
control inputs MPOT1−UP and MPOT1−DOWN
If the output value is within the limits, the output signal follows the selected control function
MPOT1−UP, MPOT1−DOWN or no action.
