This manual contains clearly marked warning information which is intended for your personal
safety and to avoid any unintentional damage to the product or connected appliances.
Before installing, commissioning or using the frequency converter, please read the warning
information contained in Vacon 20X Installation Manual.
Please read the following additional safety instructions carefully.
Only Vacon authorized, trained and qualified personnel are allowed to install, operate and
maintain the drive.
1.1Danger
These warnings are intended to personnel responsible for grounding the frequency converter.
Ignoring the following instructions can be extremely dangerous and may cause
death or severe injury.
Ground the frequency converter to ensure personnel safety and to reduce electromagnetic interference.
After disconnecting the AC drive from the mains or from the DC input supply,
wait until the indicators on the keypad go out (if no keypad is attached, see the
indicators on the cover). Wait an additional 30 seconds before starting any work
on the connections of Vacon 20X Drive. After expiration of this time, use measuring equipment to absolutely ensure that no
absence of voltage before starting any electrical work!
1.2Warnings
The touch current of VACON
dard EN61800-5-1, a reinforced protective ground connection must be ensured.
See Vacon 20X Installation Manual for further information.
Never work on the photovoltaic generator or frequency converter and its input/
output cables when the frequency converter is connected to the mains or to the
photovoltaic generator.
Before performing any measurement on the frequency converter, disconnect or
isolate the mains supply voltage or the DC input supply.
Do not touch the components on the frequency converter or on the string box
cabinet that have high DC voltage.

2.SOLARPUMP APPLICATION
The VACON® 20 CP/X drive contains a preloaded application for instant use.
The parameters of this application are listed in chapter 3.3 of this manual and explained in
more detail in chapter 4.
2.1Specific functions of Vacon Solar pump application
The Vacon Solar Pump allows flexible use of VACON® 20 CP/X frequency converters. This dedicated application SW was developed to drive a Solar Pump with an optimized MPPT (Maximum
Power Point Tracking) for 20X 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.
The drive can be controlled through I/O terminals, a fieldbus or the optional keypad.Two programmable control places and sources for the frequency reference are available, for easy local/remote control.
Frequency reference can be direct (analogue input, preset speeds or fieldbus) or controlled by
the internal PID regulator.
All the functionalities can be controlled through a fieldbus.
The motor identification function allows automatic optimization of the voltage/frequency curve,
for a optimal torque response also at low motor speed.
It is possible to install one optional board for I/O expansion.
Underload protection can be managed by measuring Motor torque (standard sensorless mode)
or by measuring the water flow with a flow meter sensor. This sensor can be an analogue signal or a digital input. With this sensor it is possible to measure the water flow [litres/min] and
the total volume of the water flow [m
Sleep mode can be enabled or disabled with a parameter.
Digital inputs can be used to measure water levels (minimum and maximum).

2.3Optional boards
One optional I/O expansion board can be installed into the slot on the right side of the drive. The
following boards are supported:
OPTB1: 6 Digital Inputs-Outputs
The first 3 terminals are reserved as digital inputs (DIN7, DIN8, DIN9). The second 3 terminals
can be used as inputs (DIN10, DIN11, DIN12) or digital outputs (EO1, EO2, EO3). The number of
terminals used as input must be declared in parameter P2.24 (hidden if the board is not installed). This number determines the higher value for the selection of the digital input connected to a certain logical function. It also changes the visibility of parameters for the selection of
digital outputs function (P5.9, P5.10, P5.11).
OPTB2: 1 Thermistor Input, 2 Relays Outputs
Response to thermistor fault can be programmed with parameter P9.16. Relays functions can
be programmed with parameters P5.9, P5.10 (hidden if the board is not installed).
OPTB5: 3 Relays Outputs
Relays functions can be programmed with parameters P5.9, P5.10, P5.11 (hidden if the board
is not installed).
OPTB9: 5 Digital Inputs, 1 Relay Output
The higher value for the selection of the digital input (DIN7, DIN8, DIN9, DIN10, DIN11) connected to a certain logical function is set to 11. Relay functions can be programmed with parameters P5.9 (hidden if the board is not installed).
OPTBF: 1 Analogue Output, 1 Digital Output, 1 Relay Output
The digital output can be programmed with parameter P5.12. The digital output can be programmed with parameter P5.9. Parameters are hidden if the board is not installed.
OPTC3/E3: Profibus DPV1 fieldbus board

fieldbus board. The converter can then be controlled, monitored and programmed from the
Host system.OPTE3 option board also supports connection from DP Master (class 2) if DP-V1
is enabled. In this case, the Master class 2 can initiate a connection, read and write parameters
using the PROFIdrive Parameter Access service, and close the connection. The PROFIBUS DP
fieldbus is connected to the OPTE3 board using a 5-pin pluggable bus connector. The only difference between OPTE3 and OPTE5 boards is the fieldbus connector.

The converter can then be controlled, monitored and programmed from the Host system. Vacon DeviceNet Board is connected to the fieldbus through a 5-pin pluggable bus connector
(board OPTC7/E7).
OPTCI: Modbus TCP fieldbus board
Vacon 20CP/X frequency converters can be connected to Ethernet using an Ethernet fieldbus
board OPTCI. Every appliance connected to an Ethernet network has two identifiers; a MAC address and an IP address. The MAC address (Address format: xx:xx:xx:xx:xx:xx ) is unique to the
appliance and cannot be changed. The Ethernet board's MAC address can be found on the
sticker attached to the board or by using the Vacon IP tool software NCIPConfig. Please find
the software installation at www.vacon.com. In a local network, IP addresses can be defined by
the user as long as all units connected to the network are given the same network portion of
the address. For more information about IP addresses, contact your Network Administrator.
Overlapping IP addresses cause conflicts between appliances.
OPTCP: Profinet fieldbus board
Vacon 20CP/X frequency converters can be connected to Ethernet using an Ethernet fieldbus
board OPTCP. Every appliance connected to an Ethernet network has two identifiers; a MAC
address and an IP address. The MAC address (Address format: xx:xx:xx:xx:xx:xx ) is unique to
