Keypad motor
potentiometer
Function
The reference percentage does not change.
â–²
–
The reference percentage increases at the set ramp.
Pressed briefly: Reference percentage increases by 0.1%.
–
â–¼
The reference percentage decreases at the set ramp.
Pressed briefly: Reference percentage decreases by 0.1%.
The reference percentage is reset to its initial value.
WARNING
If a negative reference value is set, the drive is accelerated by pressing the button â–¼.
Limit
The reference values are limited via parameters
Minimum Reference Percentage 518 and Maximum
Reference Percentage
519.
Direction of rotation reversal
If parameter
Minimum Reference Percentage 518 is set to zero, the direction of rotation of the drive
can be reversed via the motorpoti function.
Note
In order to be able to select menu "Poti P" on the operator panel,
Reference Percentage Source 1 476
or
Reference Percentage Source 2 494 must be set to "5 - Keypad-Motorpot.". By default, Reference
Percentage Source 2
494 is set to "5 - Keypad-Motorpot".
Keypad motorpoti as reference value
The function "Keypad motorpoti" can be selected via the following parameters:
−
Reference Percentage Source 1 476
−
Reference Percentage Source 2 494
See chapter 7.5.2 "Reference percentage channel".
If you leave menu "Poti P", the drive cannot be controlled via the operator panel and remains in the
previous status.
For starting, stopping and reversing the direction of rotation of the drive via the operator panel, pa-
rameter
Local/Remote 412 must be set appropriately (Selection "3 - Control via Keypad" or "4 - Con-
trol via Keypad+Cont."). The factory settings enable control via the operator panel and via digital in-
puts. See chapter 7.3.1 "Control".
Addition of reference values
If the reference value of the motorpoti function is added to another reference value, (via
Reference
Percentage Source 1
476 plus Reference Percentage Source 2 494):
− If the value of
Maximum Reference Percentage 519 is reached and the other reference value is
increased, the output value of the motorpoti function is reduced. It is reduced, so that the sum of
both reference values is equal to the maximum reference percentage value.
− If the value of
Minimum Reference Percentage 518 is reached and the other reference value is
reduced, the output value of the motorpoti function is increased. It is increased, so that the sum of
both reference values is equal to the minimum reference percentage value.
− In the settings for
Operation Mode 495 = "1 - (+/-reference)" or "3 - inverted", the point of re-
versal of direction of rotation can be shifted by the output value of the motorpoti function. The
drive changes its direction of rotation if the total of the two reference values changes the sign.
