3.3 INSTALLATION ACCORDING TO THE EUROPEAN DIRECTIVE OF
ELECTROMAGNETIC COMPATIBILITY

The inverters with C3 option (CFW700...C3...) have internal C3 RFI filter to reduce electromagnetic
interference. These inverters, when properly installed, meet the requirements of the directive of
electromagnetic compatibility (2014/30/EU).

The CFW700 inverter series has been designed only for industrial applications. Therefore, the
emission limits of harmonic currents defined by the standards EN 61000-3-2 and EN 61000-3-2/A
14 are not applicable.

3.3.1 Conformal Installation

1. Inverters with built-in C3 RFI filter CFW700...C3...

2. Frame sizes A to D inverters with built-in C3 RFI filter capacitors grounding screws and frame
size E with J1 cable in the position (XE1). For more information see Figure A.8 on page

214.

3. Shielded output cables (motor cables) and connect the shield at both ends (motor and
inverter) with a low impedance connection for high frequency. Use PCSx-01 kit supplied
with frame sizes A, B and C inverters. For frame sizes B and C with degree of protection
IP55, use the PCSC-03 shield kit. For frame sizes D and E inverters use the clamps supplied
with the product. Ensure good contact between the cable shield and the clamps. Refer to

Figure 3.4 on page 19 and keep the proper separation from other cables according to
Item 3.2.6 Cable Distances on page 24. The maximum motor cable length and conduction

and radiated emission levels are presented at Table B.7 on page 234. Use an external RFI
filter at the input of the inverter if necessary to have a lower emission level and/or a longer
motor cable length. For more information (RFI filter commercial reference, motor cable length
and emission levels) refer to Table B.7 on page 234.

4. Shielded control cables and separate the remaining cables according to Item 3.2.6 Cable

Distances on page 24.

5. Inverter grounding according to the instructions on Item 3.2.4 Grounding Connections on

page 19.

6. Grounded power supply.

Keypad (HMI) and Basic Programming

Application examples:

 Flow control or pressure in a pipe system.

English

 Temperature of a furnace or oven.

 Dosing of chemicals in tanks.

The following example defines the terms used by the PID controller.

A pump used in a water pumping system where is necessary to control the pressure of the
pipe. A pressure transducer is installed in the pipe and supplies an analog feedback signal
to the CFW700, which is proportional to the water pressure. This signal is called the process
variable, and can be visualized at the parameter P1012. A setpoint is programmed in the
CFW700 via keypad (P1025), through an analog input (such as a 0-10 V or 4-20 mA signal) or
via communication network. The setpoint is the desired water pressure value that the pump is
supposed to produce, regardless of the consumption variations at the pump output at any time.

It is necessary to set the parameter P0221 or P0222 to 7 = SoftPLC for the operation of the
PID Regulator application.

Definitions:

 The Function 1 of the Application at parameters P0231 or P0236 represents the value of

the PID Setpoint.

 The Function 2 of the Application at parameters P0231 or P0236 represents the value of

the PID Feedback.

 The Function 1 of the Application at parameters P0251 or P0254 represents the value of

the PID Setpoint.

 The Function 2 of the Application at parameters P0251 or P0254 represents the value of

the PID Feedback.

 The Function 1 of the Application at parameters P0263 or P0270 represents the value of the

Manual/Auto command.

 The Function 1 of the Application at parameters P0275 to P0279 represents the VP>VPx

logical condition.

 The Function 2 of the Application at parameters P0275 to P0279 represents the VP<VPy

logical condition.

The PID setpoint can receive an analog input signal (AI1 or AI2). It is necessary to set P1016
to 1 = AIx and select which analog input will be used. The analog inputs are set at P0231 (AI1)
or P0236 (AI2) and it is necessary to program it to 5 = Function 1 of the Application in order to
enable the analog inputs for the operation. The following alarm message will be displayed in
case it is not properly done: “A770: Set AI1 or AI2 for Function 1 of the Application”.

The PID setpoint value can be presented via analog output AO1 or AO2. It is necessary to set
P0251 (AO1) or P0254 (AO2) to 17 = Function 1 of the Application. The full scale value of the
variable is 100.0 % and corresponds to 10 V or 20 mA.

30 | CFW700

Keypad (HMI) and Basic Programming

The PID feedback can receive an analog input signal (AI1 or AI2). It is necessary to set P0231
(AI1) or P0236 (AI2) to 6 = Function 2 of the Application in order to enable the analog inputs for
the operation. The following alarm message will be displayed in case it is not properly done:
“A772: Set AI1 or AI2 for Function 2 of the Application”.

In case the analog inputs (AI1 and AI2) are programmed with the same function, PID Setpoint
or Feedback, the following alarm message will be displayed and the application will not be
enabled: “A774: AI1 and AI2 were set for the same function”.

The value of the PID feedback can be presented via analog output AO1 or AO2. It is necessary
to set P0251 (AO1) or P0254 (AO2) to 18 = Function 2 of the Application. The full scale value of
the variable is 100.0 % and corresponds to 10 V or 20 mA.

The Manual/Auto control is done by a digital input (DI1 to DI8). It is necessary to set one of the
DI parameters (P0263 to P0270) to 20 = Function 1 of the Application. If more than one digital
input is set for this function, the logic operation will consider only the command of the high
priority level digital input, where: DI1>DI2>DI3>DI4>DI5>DI6>DI7> DI8. If any of the digital inputs
is set, the PID controller will work only in automatic (Auto) mode.

The Manual/Auto input is active when it is in 24 V indicating automatic control and it is inactive
in 0 V indicating manual operation.

The digital outputs (DO1 to DO5) can be programmed to trigger comparison logics with the
process variable (PV). In order to do that, it is necessary to set one of the DO’s parameters
(P0275 to P0279) to 34 = Function 1 of the Application (VP>VPx) or 35 = Function 2 of the
Application (VP<VPy).

Option Kits and Accessories

7.1.7 24 Vdc External Control Power Supply - CFW700...W1...

The use of this option kit is recommended with communication networks (Profibus, DeviceNet,

English

etc.), since the control circuit and the network communication interface are kept active (with
power supply and responding to the network communication commands) even in the event of
main power supply interruption.

Inverters with this option have a built-in DC/DC converter with a 24 Vdc input that provides
adequate outputs for the control circuit. Therefore, the control circuit power supply will be
redundant, i.e., it can be provided either by a 24 Vdc external power supply (connection as
shown in Figure 7.1 on page 60 a) or b)) or by the standard internal switched mode power
supply of the inverter.

Observe that the inverters with the external 24 Vdc power supply option use terminals XC1:34
and 36 or XC1:15 and 16 as the input for the external power supply and no longer as the output
like in the standard inverter (Figure 7.1 on page 60).

In case of interruption of the external 24 Vdc power supply, the digital inputs/outputs and analog
outputs will no longer be fed, even if the mains power is on. Therefore, it is recommended to keep
the 24 Vdc power supply always connected to the terminals XC1:34 and 36 or XC1:15 and 16.

7.2 ACCESSORIES

The accessories are installed to the inverter easily and quickly using the “Plug and Play” concept.
When an accessory is connected to the slots, the control circuit automatically identifies the
model of this accessory and its code is presented in the parameter P0028. The accessory shall
be installed with the inverter power supply off.

The code and model of each available accessory is presented in the Table 7.1 on page 61.
The accessories can be ordered individually and they will be provided in their own packaging
containing the components and guides with detailed instructions for installation, operation and
programming.
