Operating Instructions ACU
Motor potentiometer function Pot
Using the arrow keys, you can adjust the output frequency of the frequency
inverter from the Minimum Frequency 418 to the Maximum Frequency 419.
The acceleration corresponds to the factory settings (2 Hz/s) for parameter
Ramp Keypad-Motorpoti 473. Parameters Acceleration (Clockwise) 420 and
Deceleration (Clockwise) 421 are considered in the case of low acceleration
values.
Internal reference value int
The drive is in operation, i.e. output signals are present at the frequency
inverter and the current actual value is displayed. Press an arrow key to switch
to the motor potentiometer function Pot. The current frequency value is taken
over in the motor potentiometer function Pot.
Function Motorpoti (KP) inP
Using the arrow keys, you can adjust the output frequency from Minimum
Frequency 418 to Maximum Frequency 419. The frequency value adjusted via
the control unit can be linked to other reference values via the Reference
Frequency Source 475 (Chapter 15.4 "Frequency reference channel" and
15.10.2 "Motorpoti (KP)").
JOG-Frequency JOG
This function is useful for manual setup and positioning of a machine. The
frequency of the output signal is set to the entered value if the FUN key is
pressed.
Press FUN key to switch from the internal reference value int or the motor
potentiometer function Pot to parameter JOG-Frequency 489.
While keeping the FUN key pressed, press the arrow keys to adjust the
required frequency.
(The last frequency value set will be saved in parameter JOG-Frequency
489 .)
Release the FUN key to stop the drive.
(The display returns to the previous function Pot or int. or inP if function
“Motorpoti (KP)” is activated).
Reversal of the sense of rotation independent of the control signal on the terminals
Clockwise S2IND or Anticlockwise S3IND.
Cancel function and return to the menu structure.
Switch from internal reference value int or motor potentiometer function Pot to JOG-
Frequency; the drive will start.
Release the key to switch to the sub-function and stop the drive.
Start drive; alternative to control signal S2IND or S3IND.
Stop drive; alternative to control signal S2IND or S3IND.
If you press the ENT key, the Sense of Rotation is changed independent of the
signal on the terminals Clockwise S2IND or Anticlockwise S3IND.
If the Minimum Frequency 418 is set to 0.00 Hz, the sense of rotation of the
motor changes as soon as the sign of the reference frequency value changes.
