Delta Electronics participated in Middle East Electricity show in Dubai

Delta Electronics has showed its products and solutions in the MEE exhibition held in Dubai (1-3 March).

Various products were demonstrated in the booth, including PLCs, HMIs, Drives, Servo and Delta Multi-Pump Solution (DMPS).

Visitors from all around the middle east were present, good connections were made and costumers showed lots of interest in our products.

Due to the fact that oil prices are going down, and most of the projects in the Gulf area are oil and gas related projects, lots of costumers moved their attention to Delta as an economic alternative to other brands.

See you soon in Hannover Messe, April.

How to connect ASDA-A2 to a PROFINET network

Problem: our ASDA-A2 servo drive is a very good high-end servo drive, except for the fact that it does not support PROFINET until now, and for one of our potential costumers we needed such functionality.

This document explains the solution that we did for such problems.

System structure: the system is basically to control a load with our ASDA-A2-M servo drive, which has CANOpen communication. The controller is a PROFINET Master (e.g. Siemens S7 PLC).

Here we used a gateway, to bridge the connection between PROFINET and CANOpen, the gateway used was IXXAT CME/  PN from HMS.

ASDA-A2 configuration: the servo drive’s parameters were adjusted to the connected motor, and to be controlled by a CANOpen Master, below are the main parameters for such a configuration:

Parameter Value Discerption
P1-01 0x000B Control Mode and Output Direction (CANopen Mode)
P1-44 1000 Electronic Gear Ratio (1st Numerator) (N1)
P1-45 1 Electronic Gear Ratio (Denominator) (M)
P3-00 0x0004 Communication Address Setting
P3-01 0x0403 Transmission Speed (1.0M bits / second)

 

The ASDA-A2-M CANOpen interface supports up to 4 PDOs duplex (transmit and receive), each PDO has a length of 8 bytes.

For an explanation for the commands needed to control the drive from CANOpen, please refer to the document CANopen for ASDA-A2_M_EN_20120921

IXXAT CME/PN gateway: this gateway can be parametrized using its own software (CANopen Configuration Studio for IXXAT CME-PN 2.1). In the software the ESD file for the ASDA-A2 can be loaded, and the values that need to be transferred are selected. The variables selected for this application are as follows:

Index Sub-Index Size (Bits) Parameter name
RPDO1
6040 00 16 Controlword
6081 00 32 Profile velocity
RPDO2
607A 00 32 Target Position
60FF 00 32 Target Velocity
RPDO3
6083 00 32 Profile acceleration
6084 00 32 Profile deceleration
RPDO4
6060 00 8 Modes of operation
6098 00 8 Homing method
607C 00 32 Home offset
TPDO1
6041 00 16 Statusword
6077 00 16 Torque actual value
6078 00 16 Current actual value
TPDO2
6064 00 32 Position actual value
TPDO3
606C 00 32 Velocity actual value
TPDO4
603F 00 16 Error code

 

After the configuration has been made, a compilation is done in the software, and then the GSDML file is exported to be used in the PROFINET master as a device .

full screen is recommended

 

And the last step is to download the configuration to the IXXAT gateway using the USB cable (mini USB port).

PROFINET Master: here in this case a Siemens PLC is used (CPU1516-3 PN), first step in the hardware configuration the GSDML file is loaded, and then the device is inserted in the HW configuration. After inserting the device, it will automatically assign inputs and outputs areas for the mentioned variables, where they can be used later in the PLC program to control the servo drive.

we hope this will be of help to your application.
