6.3 Controlling the Motor via the Control Unit
The control unit enables controlling the connected motor in accordance with the
selected operation mode of parameter
Local/Remote 412.
Note: In order to be able to control the drive via the control unit, the digital
controller input S1IND must be connected and set to "High-Signal" in
order to enable the output stage.
Warning! Switch off power supply before connecting and disconnecting control
terminal S1IND.
When the frequency inverter is disconnected from power supply,
dangerous voltage may still be present at the mains, DC link voltage
and motor terminals for some time. Wait for some minutes until the DC
link capacitors have discharged before starting to work at the unit.
• The unit may only be connected with the power supply switched off.
• Verify that the frequency inverter is de-energized.
: When the RUN key was pressed, the drive was in operation already.
The CTRL menu branch can be accessed via the navigation
within the menu structure. The CtrL function contains sub-
functions which are displayed according to the operating point
of the frequency inverter.
Press the RUN key at any point in the menu structure to switch
to the motorpoti function Pot or the internal reference value
int if the drive is already in operation.
Motor potentiometer function Pot
Use the arrow keys to 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. The parameters Acceleration (Clockwise) 420
and
Deceleration (Clockwise) 421 are considered in the case
of low acceleration values.
