Description
The PPC-125-U-PDP is a universal axis control unit for controlling hydraulic axles via an integrated Profibus DP interface. It can be used as a universal Axle controllers are used in hydraulic drives.
Key features anad characteristics:
- Setpoint specification, actual value feedback, control byte and status byte via a fieldbus (Profibus DP).
- SSI sensor interface or analogue sensor interface (0–10 V or 4–20 mA).
- Simple and user-friendly sensor scaling.
- Position resolution up to 1 μm (SSI interface).
- Speed resolution 0.005 mm/s.
- Speed profiles (fast and slow).
- PQ control function with pressure-limiting control.
- The principle of distance-dependent braking for robust control.
- NC profile generator for a constant speed, setpoints in mm, mm/s and mm/s².
- High positioning accuracy achieved through the use of drift compensation.
- Advanced control technology with a PT1 controller.
- Ideal for use with covered proportional valves and zero-cut control valves.
- Fault diagnosis and advanced functional testing.
- Simplified parameter setting with the WPC-300 software.
- Additional force or differential pressure control, which operates independently or as a backup pressure-limiting control.
- Optional setting of a second position and a second speed in jog mode or rapid traverse.
Typical applications:
- Positioning actuators
- High-speed transport drives
- Manipulation axes
- Forming machines with position and pressure control
- Feed drives
How it works:
The module combines position control with digital position measurement and pressure control, or -Monitoring with integrated communication via Profibus DP. The axis can be operated either in point-to-point control mode (distance-dependent braking) or in NC mode.
