5.6.7 Motor potentiometer function
As the drive is to be operated for basic commissioning using the motor potentiometer
on the control unit, the speed or frequency limits (motor potentiometer n-max, motor
potentiometer n-min), the acceleration time (motor potentiometer ramp up) and the
braking time (motor potentiometer ramp down) are to be adjusted for the motor
potentiometer function.
Switch the 8230 frequency inverter on by pressing the "Start" key on the control unit
and run to maximum speed with the motor potentiometer (+ or - keys respectively)
and then return to 0.
If overvoltage shut-downs should occur, eg. message “Overvoltage, link”, extend the
braking ramp for the motor potentiometer function and, if necessary, reduce the
regenerative current limit.
The parameters required are located under "02 = Application parameters".
5.7 Terminal strip wiring
Operation of the 8230 frequency inverter and demand preset through the terminal
strip is activated by switching from manual to automatic operation. For this, with the
8230 frequency inverter switched off, bridge terminals :6 and :1 (+24 V).
Wire the terminal strip according to the requirements involved in the plant. See also
section 2.7.2.
Switch the 8230 frequency inverter on by applying the ON signal (terminal :5). Run
the drive to maximum speed by increasing the demand signal. Check the braking
ramps by suitable presets (Stop, Fast Stop) from medium speed and then from
maximum speed. If necessary, extend the ramps (under "02 = Application
parameters").
The following applies when using the main demand (terminal :27/:28):
10 V = max. speed = max. main demand (%)
*
rated speed
When operating with field weakening the parameter for maximum main demand must
be increased to values above 100 %. This parameter is available on the main menu
under "04 = Analog I/Os".
The speed limit and reference overspeed parameters must also be adjusted as
required.
Switch the drive off by cancelling the ON signal.
