7.3 Special parameter settings for DMX/DMH
Some parameters have been adapted to DMX/DMH dosing
pumps. These parameters differ from the default settings
mentioned in the supplier manual for the VFD.
Warning
When resetting the VFD to default settings, the
special parameter settings for DMX/DMH are
overwritten. The special parameters must be set
again.
7.3.1 Mandatory settings
Do not set P506 "automatic fault acknowledgement"
to 6 "always".
Caution
In case of an active error (e. g. short-circuit to earth /
short circuit), the VFD restarts continuously and
damages the system, because P428 is set to 1 "on".
Warning
Danger of malfunction of the VFD with DMX/DMH
dosing pump. Do not change the following settings.
