All Rights Reserved 2. Before you begin Read and understand these instructions before performing any procedure with this inverter, in order to completely and correctly utilize excellent performance of this unit. Besides this user manual, you will find in the chapter "Documentation structure"which manuals we advice you to read to develop software communicating with Altivar 21 If you need support, please contact our sales offices After reading this instruction manual, please keep it handy for future reference A DANGER HAZARDOUS VOLTAGE Read and understand the installation Manual before installing or operating the Altivar 21 inverter Installation, adjustment, repair, and maintenance must be performed by qualified personnel. The user is responsible for compliance with all international and national electrical standards in force concerning protective ground ing cfa‖ equipment Many parts of this variable speed drive, including the printed circuit cards, operate at the line voltage. DO NOT TOUCH Use only electrically insulated tools DO NOT touch unshielded components or terminal strip screw connections with voltage present. DO NOT short across terminals Pa and Pc or across the dC bus capacitors Install and close all the covers before applying power or starting and stopping the inverter Before servicing the variable speed drive Disconnect all power Place a DO NOT TURN ON" label on the variable speed drive disconnect. Lock the disconnect in the open position Disconnect all power including external control power that may be present before servicing the inverter. WAIT 15 MINUTES to allow the dc bus capacitors to discharge. Then follow the dc bus voltage measurement procedure given in the Installation Manual to verify that the dc voltage is less than 45 VDC. The inverter LEDs are not accurate indicators of the absence of dc bus voltage Electric shock will result in death or serious injury. A CAUTION DAMAGED EQUIPMENT Do not install or operate any inverter that appears damaged Failure to follow this instruction can result in injury or equipment damage 3. Introduction Thank you for purchasing the Altivar 21 inverter equipped with an embedded Modbus port The present guide contains information about the installation of the altivar 21 inverter on a Modbus network and describes the Modbus services available o y using the Modbus port of the Altivar 21, data communication can be made with a PLC, a host computer or other devices via a Modbus B etwork Data exchanges give access to all Altivar 21 functions Control (start, stop, reset, setpoint), Monitoring(status, current, voltage, thermal state.), Diagnostics(alarms), Configuration The communication port has an RJ45 connector for the connection to the network. At the physical layer, it supports 2-wire R$485 and transmission speed at 9600 or 19200 bps 4 Modbus functions are available (16#03)Read Holding Registers 6(16#06)Write Single Register 16 (16*10)Write Multiple Registers 43/14 (16#2B/0E)Read Device Identification Function 3 has a restricted implementation with length 1 Read one word"), it permits to read any parameter of the inverter, one by one with lengths 2 to 5("Read indirect block"), it permits to read a particular block of 2 to 5 indirect parameters. These 5 parameters can be configured through the operation panel to relevant monitoring parameters Function 16 has a restricted implementation with length 1 Write one word), it permits to write any writable parameter of the inverter, one by one with length 2(Write indirect block"), it permits to write a particular block of 2 indirect parameters. These 2 parameters can be configured through the operation panel to relevant control parameters 4 Documentation structure ■ Modbus atv21 manual This manual describes Connection to the network Configuration of the communication- related parameters Modbus services supported Parameter list ( additional to the ATV21 user manual) YouwillalsofindimportantinformationinotherAltivar21technicaldocuments.theyareavailableonthewebsitewww.telemecanique.col and on the cdrom delivered with each inverter. ■ATV21 user manual This manual describes How to assemble the inverter How to connect the inverter The functions and the parameters of the inverter, How to use the operation panel You will find in this manual the address and possible values of the parameters of the inverter Note: In both manuals, the address of the parameters is named"Communication number"and coded in hexadecimal (16 # 5.
