Invertek Drives 82-PFNET-IN Profinet IO Interface User Guide

Invertek Drives 82-PFNET-IN Profinet IO Interface

Overview

This option module is specifically designed to be used with the Optidrive P2 and Optidrive Eco range of variable speed drive products and is intended for professional incorporation into complete equipment or systems. If installed incorrectly it may present a safety hazard. Before commencing installation and commissioning, the user should ensure they are fully familiar with the Optidrive P2, and in particular, have read the important safety information and warnings contained in the Optidrive P2 / Optidrive Eco User Guide.

Note:
This User Guide is intended to be used with Optidrive P2 & Eco firmware version 2.00 or later. The firmware version of the drive can be displayed in parameter P0-28. Previous versions of firmware can be upgraded using Optitools Studio PC software. Contact your local Invertek Sales Partner for further Information.

Available Functions
The PROFINET interface is intended to be installed in the Optidrive option slot and allows the Optidrive to be connected to a PROFINET network. The interface offers the following functionality:

•  Cyclic Process Data Exchange
• 4 Input Words from the network master to the Optidrive
•  4 Output Words from the Optidrive to the network master

GSD File
A GSDXML fi le for the interface can be obtained from invertekdrives.com

IP Address Confi guration
If it is desired to change the IP Address, an IP address confi guration tool is available for download from invertekdrives.com

Compatibility
This Option is suitable for use on the following product ranges:

Optidrive Setup

•  Set the drive to Fieldbus control mode by setting parameter P1-12 = 4
•  Ensure Advanced Parameter Access is enabled on the drive-by setting P1-14 = 101
•  By default, DHCP is enabled, and the module IP address will be automatically assigned. If a fixed IP address is desired, download the IP address configuration software from invertekdrives.com

Data Mapping
The Optidrive P2 and Optidrive Eco support a 4-word cyclic process data exchange. The format and data contained in these words are shown below.

Input Data (PDI) Telegram
This part of the memory contains the real-time drive commands sent from the network master to the Optidrive, allowing the Optidrive to be controlled. The functions of the first two data words (PDI 1 and PDI 2) are fixed, to allow basic control over the drive operation and output frequency to be achieved. The configuration of the remaining two words can be adjusted by the user.

PDI Word 1: Fixed Function: Drive Control Word
A 16 Bit control word is used to control the behavior of the drive when P1-12 = 4. The bits function as follows:

the highest priority, bit 0 has the lowest priority (bit 3>bit 1>bit 0). For normal run/ stop control, Bit 0 only should be used.

Note that the start/stop (bit 0), fast stop (bit 1) and coast stop (bit 3) can only be used to control the drive when P2-37= 0 to 3. If P2-37 > 3, the start/stop function is

controlled directly by the drive control terminals. The Reset function (bit 2) will operate providing that the drive is set for Fieldbus control P1-12 = 4.

1| Fast Stop Select| 0   : No Function

1   : Drive Stop with Deceleration Ramp 2

2| Fault Reset| 0   : No Function

1   : Rising Edge fault reset request

3| Coast Stop| 0   : No Function

1   : Drive Coasts to stop. Overrides bit 0

4–15| Not Used

PDI Word 2: Fixed Function: Frequency Setpoint

This word is used to transfer the frequency setpoint to the Optidrive. The input data is a 16bit signed integer including one decimal place. For example, a value of 500 represents a frequency setpoint to the Optidrive of 50.0Hz, value 123 gives 12.3Hz. For a negative (reverse) speed reference, a negative value can be transferred to the drive, where the MSB of the high byte must be

1. For example, -1(0xFFFF) gives -0.1Hz. -234(0xFF16) gives -23.4Hz.
   The allowed input value range is from -5000 to +5000; however, the drive output speed will be limited by the maximum speed set by P1-01.

PDI Word 3 : User Defined Function
The function of this data word can be selected by the user using drive parameter P5-14. The possible setting options are shown below: 0: Torque limit/reference (Optidrive P2 Only) – This option must be selected if the drive output torque limit/setpoint is to be controlled from the Fieldbus. This also requires setting P4-06 = 3. The input data is a 16bit unsigned integer including one decimal place. For example, a value of 500 represents a torque setpoint to the Optidrive of 50.0%, value 123 gives 12.3%. The allowed input value range is from 0 to +2000; however, the drive output torque will be limited by the maximum limit set by P4-07. 1: User PID reference register – This option allows the setpoint to the PID controller to be received from the Fieldbus. In order for this option to be used, P9-38 must be set to 1, and the PID User setpoint must not be utilized within the drive PLC function.
User register:
The value received by the drive-in PDI 3 is transferred to User Register 3. This option allows the function of the process data word to be defined in Parameter Group 9. In this case, User Register 3 should not be written to within any PLC function code, although the value can be read.

PDI Word 4: User Defined Function
The function of this data word can be selected by the user using drive parameter P5-13. The possible setting options are shown below: 0: Fieldbus Ramp Control – This option must be selected if the drive acceleration and deceleration ramps are to be controlled from the Fieldbus. P5-07 must also be set to 1 to enable this function.  User register The value received by the drive-in PDI 4 is transferred to User Register  This option allows the function of the process data word to be defined in Parameter Group 9. In this case, User Register 3 should not be written to within any PLC function code, although the value can be read.

Output Data
This part of the memory contains the real-time drive data returned from the Optidrive to the network master. The function of the first two data words (PDO 1 and PDO 2) is fixed. The configuration of the remaining two words can be adjusted by the user.
PDO Word 1: Fixed Function : Drive Status & Error Code:
This word contains 2 bytes with information as follows:

enabled
1| Drive Healthy| Drive Fault (Tripped)| Indicates when the drive has tripped. The fault code is indicated in the high byte as shown below
2| Auto Control Mode| Hand Control Mode| Optidrive Eco Only. Indicates when Hand control is selected
3| OK| Inhibit| Indicates the status of the STO / Hardware Inhibit circuit
4| OK| Maintenance Time Reached| Indicates that the programmable System Maintenance Time Interval has expired
5| Not in Standby| Standby| No Function Assigned
6| Not Ready| Drive Ready| Mains Power applied, No Inhibit, No Trip, Enable Input present
7| Normal Load| Low/High Mode Detected| Optidrive Eco Only. Indicates when low or high load condition is detected
8 – 15| Last / Current Fault Code| Indicates the last or current fault code. For further fault code information, refer to the Optidrive User Guide

PDO Word 2 : Fixed Function: Output Frequency
This word gives the real-time drive output frequency information. The data is a 16bit signed integer with one decimal place. e.g. value 123 means 12.3Hz. Value -234 (0xFF16) means -23.4Hz.

PDO Word 3 : Output Current
Data to be transferred in this word can be selected by the User in drive parameter P5-12. The possible settings are as follows: 0: Motor current – Output current to 1 decimal place, e.g. 100 = 10.0 Amps

1. Power (x.xx kW) Output power in kW to two decimal places, e.g. 400 = 4.00kW
2. 2: Digital input status – Bit 0 indicates digital input 1 status, bit 1 indicates digital input 2 status etc
3. Analog Input 2 Signal Level – 0 to 1000 = 0 to 100.0%
4.  Drive Heatsink Temperature – 0 to 100 = 0 to 100°C
5.  User register 1 – User Defined Register 1 Value
6.  User register 2 – User Defined Register 1 Value
7.  P0-80 value – User Selected data value

PDO Word 4 : User Defined
Data to be transferred in this word can be selected by the User in drive parameter P5-08. The possible settings are as follows: 0 : Output Torque (Optidrive P2 Only) – 0 to 2000 = 0 to 200.0%

1. Output Power – Output power in kW to two decimal places, e.g. 400 = 4.00kW
2.  Digital Input Status – Bit 0 indicates digital input 1 status, bit 1 indicates digital input 2 status etc
3. Analog Input 2 Signal Level – 0 to 1000 = 0 to 100.0%
4. Drive Heatsink Temperature – 0 to 100 = 0 to 100°C
