The Analysis For Rexroth A6VE Piston Motor Common Breakdown:
1. Irregular voltage supply to the control unit of the A6VM motor
can disrupt its performance and lead to unpredictable behavior,
potentially harming sensitive electronics; if the hydraulic pump’s
voltage also fluctuates, installing voltage stabilizers and
performing electrical system upgrades are necessary to secure
proper operation for consistent electrical stability always.
2. Failure of quick start in the Rexroth A6VM hydraulic motor can
result from delayed system response, unsuitable oil temperatures,
or wear in internal components. Inability to rapidly achieve the
required pressure and flow during startup may disrupt the entire
hydraulic system's responsiveness. It is recommended to conduct
dedicated inspections of the startup system, optimize control
parameters, and check the condition of hydraulic oil and internal
components to ensure a smooth and rapid start for this piston
motor.
3. Sensor Failure: Signal loss may stem from connector corrosion
or shield damage. Check 4-20 mA loop integrity and upgrade to
IP67-rated connectors.
