This parameter defines when the reference of the motor potentiometer is set to 0. There are 3 selections in the reset function: no
reset, reset when the drive stops, or reset when the drive is powered down.
Selection
number
Selection name Description
0
No reset
The last motor potentiometer frequency reference is kept through the stop state and kept in
memory when a power-down occurs.
1
Stop state
The motor potentiometer frequency reference is set to 0 when the drive goes to the stop state,
or when the drive is powered down.
2
Powered down
The motor potentiometer frequency reference is set to 0 only when a power-down occurs.
10.126 (ID 370) Motor Potentiometer Memory Reset (Frequency Reference)
Location in the menu:
P2.2.29
(PID Control Application)
P2.2.1.17
(Pump and Fan Control Application)
Use this parameter to set the logic for the resetting of the PID reference of the motor potentiometer.
10.127 (ID 371) PID Reference 2 (Place A Additional Reference)
Location in the menu:
P2.2.1.4
(Pump and Fan Control Application)
Use this parameter to select the reference place for PID controller reference when PID reference is activated.
These parameters set the low and high limits of the signal selected with parameter
ID 356
.
If the PID reference 2 enables input function (
ID 330
)= TRUE, this parameter defines which reference place is selected as PID control-
ler reference.

If value 6 is selected for this parameter, the functions Motor potentiometer
DOWN and Motor potentiometer UP must be connected to digital inputs
(parameters ID 417 and ID 418).

10.128 (ID 372) Supervised Analog Input
Location in the menu:
P2.3.2.13
(Pump and Fan Control Application)
Use this parameter to select the analog input for which to set the limit supervision function.
10.129 (ID 373) Analog Input Limit Supervision
Location in the menu:
P2.3.2.14
(Pump and Fan Control Application)
Use this parameter select the limit supervision function for the selected analog input.
If the value of the selected analog input goes under/over the set supervision value (parameter
ID 374
), this function generates a
message. The message is generated through the digital output or the relay outputs depending on to which output the analog input
supervision function (parameter
ID 463
) is connected.
