Motor potentiometer

The reference speed (or the percentage reference value) of the drive can be set via digital control
signals or with the operator panel:
− Digital control signals: Function "Motorpoti via digital inputs"
− Operator panel: Function "Keypad motorpoti"
The functions "Motorpoti via digital inputs" and "Keypad motorpoti" can be selected via the following
parameters.
Via the reference frequency channel:
−
Reference Frequency Source 1
−
Reference Frequency Source 2
Via the reference percentage channel:
−
Reference Percentage Source 1
−
Reference Percentage Source 2
The functions "Motorpoti via digital inputs" and "Keypad motorpoti" (control via opera-
tor panel) can be selected at the same time. To that end, one of the functions must
be selected for
ence Frequency Source 2
keypad and digital inputs.

Operation modes of motor potentiometer

474 Operation Mode (motorpoti)
474 of the functions "Motorpoti via digital inputs" and "Keypad motorpoti" defines
Operation Mode
the behavior of the function at different operating points of the frequency inverter. When the drive
starts, it can accelerate to the last reference value set. Upon dataset changeover, the set reference
value can be taken over.
Operation Mode
0 - Not Latching
1 - Latching
2 - Taking Over
3 - Taking Over and Latching
7.5.3.2

Ramp of motor potentiometer

473 Ramp Frequency-Motorpoti
The speed of the modification of the reference value (ramp) can be set via parameter
473. The ramp is used in the following controls with the reference frequency channel:
cy-Motorpoti
− Motorpoti via digital inputs
− Keypad motorpoti (control via operator panel)

The drive accelerates to the set minimum reference value upon
each start. Factory setting.
When started, the motor accelerates to the reference value se-
lected before the switch-off. The reference value is also stored
when the device is switched off.
Use this operation mode for dataset changeover of the reference
value channel. The current reference value is used when the
motorpoti function is activated.
This operation mode combines the operation modes 1 and 2.
