In addition to the Software Components (Drive Firmware and Software) , a
Sytronix system requires following components:
●
Motor, coupling and pump
●
One pressure sensor at the pump output side
●
In order to keep the positive direction of pump (which gener‐
ates pressure), the direction of the electrical drive (Rexroth
EFC 5610 with MOT-FC) of DRn system has already been
set as default to run reverse, as the motor and pump have
been coupled face to face.
●
Pressure values are always meant to be relative to atmos‐
phere. This applies for pump data as well as sensor values.
