1. VACON 100X SOLAR PUMP APPLICATION
The Vacon AC drive contains a preloaded Vacon 100X Solar Pump application for instant use.
1.1 Specific functions of Vacon Solar pump application
The Vacon 100X Solar Pump application allows flexible use of VACON
®
100X frequency con-
verters. This dedicated application SW was developed to drive a Solar Pump with an optimized
MPPT (Maximum Power Point Tracking) for 100X supplied by Solar Panels.
The MPPT is based on 4 parallel algorithms:
• Feed-Forward Controller (to follow the radiation variations)
• Correction Controller (to compensate the temperature variations)
• Oscillation Damping Regulator (to prevent the panel entering in the “current source”
branch of the characteristic)
• Local Maxima logic (to prevent the regulator from being trapped in a local maximum
lower than absolute maximum)
Features
• The MPP Tracker controls DC voltage reference in order to find the maximum power.
• Extensive wizards for start-up, PID-control used to facilitate commissioning
• ‘Funct’ button for easy change between Local (keypad) and Remote control place. The
remote control place is selectable by parameter (I/O or Fieldbus)
• 8 preset frequencies
• Motor pontentiometer functions
•2 programmable ramp times, 2 supervisions and 3 ranges of prohibited frequencies
• Control page for easy operation and monitoring of the most essential values.
• Fieldbus data mapping
•Automatic reset
•Different pre-heat modes used to avoid condensation problems
• Maximum output frequency 320Hz
• Real-time clock and timer functions available (optional battery required). Possible to
program 3 time channels to achieve different functions on the drive (e.g. Start/Stop and
Preset frequencies)
• External PID-controller available. Can be used to control e.g. a valve using the AC
drive's I/O
• Sleep mode function which automatically enables and disables drive running with user
defined levels to save energy.
• 2-zone PID-controller (2 different feedback signals; minimum and maximum control)
• Two setpoint sources for the PID-control. Selectable with digital input
• PID setpoint boost function
• Feedforward function to improve the response to the process changes
• Process value supervision
• Maintenance counter
