●
supply is connected. When the Run button is pressed down (or 'Control by
terminals' is activated), the frequency converter will generate output.
By default, VFC 3210 is set as:
●
– The frequency converter is started or stopped by the operating panel con-
trol.
– The output frequency is set by the potentiometer on the operating panel.
After powering on, please confirm:
●
– The setting frequency is displayed (no error display).
– The monitoring parameter is consistent with the actual situation.
By default, the frequency converter displays Output frequency in run status
●
and Setting frequency in stop status as the monitoring parameters. You may
change them to other parameters as described in parameters U1.00 and
U1.10. The factory defaults are based on standard applications with standard
motors.
