Power Limitation (Vt 5041-3X/3 - Bosch rexroth SYDFE1 2X Series Operating Instructions Manual

Product description | Pressure and flow control system SYDFE1 series 2X, 3X 33/96
angle control), can have an unfavorable effect on the swivel angle control when
the corrective feature described above is active. In this case, the swivel angle
control can be stabilized by reducing or deactivating case drain oil compensation.
Reasons for pressure fluctuations can be the following:
• Process- or material-related
• Hydraulic motors with a small number of pistons
• Lifting cylinders with a low natural frequency
• Overriding closed position or velocity control loop
5.11.9 Power limitation (VT 5041-3X/3... only)
In the case of electronics variants with power limitation, a limiting value can be set
by means of a potentiometer. Alternatively, a limit value can be provided externally
to contacts 18c/20c, if jumper J2 is set in position 2-3.

Fig. 11: Power limitation
When the power limiter cuts in, the operating variables (pressure and flow) adjust
automatically according to the curve path of the set power hyperbola.
How to adjust the power control is described in chapter 8 "Commissioning" on
page 59, the adjustment of the power limitation is described in section 8.1.12
on page 70.
