Software features:
◦ Profinet IO and Ethernet IP protocols as standard, though the built in Ethernet port.
◦ Winder Function Blocks : Diameter calculation, inertia compensation, torque and taper calculation functions combine to make speed and torque control winder functions.
◦ Catching a spinning load – « fly-catching »: The fan control algorithms enable the AC20 to detect when a fan is free-wheeling and to regain control of it before running it at the commanded speed.
◦ PID Control: Multiple PID control loops can be programmed to monitor process variables and adjust the speed of the motor accordingly to achieve the required variable setpoint.
◦ Essential services (Fire mode) : Selected via digital input, Fire mode will cause the drive to run continuously at the maximum programmed speed ignoring all other control signals and alarm conditions.
◦ Energy Optimisation: Under constant speed conditions, the motor power waveforms from the drive are optimised to reduce motor energy consumption without compromising performance.
◦ Skip Frequencies: Up to 4 speed and frequency bands can be programmed, to enable resonant points on the load to be avoided, reducing vibration, wear and noise.
◦ Programmable multi-stage speed control: 8 cyclable stages can be programmed with different running speeds and times.
◦ Process Timers : Multiple hours-run timers can be programmed to generate alerts that coincide with process maintenance intervals.
◦ 70 Software ‘function blocks’ that may be interconnected with up to 200 ‘links’ provide a powerful application platform.
Parker Drive DSELite Software :
Parker drive configuration software Drive System Explorer (DSE) Lite is an easy-to-use drive configuration software package, designed to make programming your application as simple as possible without compromising on functionality.
DSE Lite is based around a straightforward block programming and an intuitive user interface which supports user-defined configurations and offers real- time monitoring and charting. DSE Lite allows the user to create, parameterize and configure user defined applications as well as parameterize and connect fixed Motor Control blocks with up to 200 ‘links’.
Thanks to the online help and pre-configured macro templates, users can achieve the optimum drive configuration without the need to navigate through complicated parameter menus.
Enhanced features of the AC20 include:
◦ High speed Ethernet connectivity
◦ Network scan feature
◦ Drive network identification
◦ Firmware installs over Ethernet
◦ Save a project to on-board Flash memory
◦ Compatibility with the AC30 Series Oscilloscope software.
