Stop Speed Reading
This function allows the user to read the pump rotational frequency
(window 232) even after a stop command, during the braking. The
function can be activated/deactivated by serial communication
(WIN 167). If activated, all the related functions (set point output,
programmable analog output – if related to the frequency, …) will
follow the frequency reading.
NOTE
The A-plus Software (optional) allows the operator to set all the programmable
feature.
