Function library Lenze8200Drive.lib Introduction 2 Introduction 2.1 General Integrate function library Lenze8200Drive.lib in your PLC program to make frequency inverter control easier. Two function blocks are required for this: 1. A function block for the parameterisation of the frequency inverter. 2. Another function block for process data exchange between PLC and frequency inverter. The parameters can be set via the PLC program. It is possible to select up to 45 parameters.
Function library Lenze8200Drive.lib Introduction 2.2 Frequency inverter parameterisation When the program is started, the parameter data shall be written only once during initialisation to the frequency inverter. The FBs L_8200Parameter and L_8200Initialization therefore have to be called in the system task PLC_PRG. · The FB L_8200Parameter is used to initialise the codes with the corresponding values.
Function library Lenze8200Drive.lib Introduction 2.2.
Function library Lenze8200Drive.lib Introduction 2.3 Process data exchange with the frequency inverter Unlike the parameter data, the process data must be cyclically exchanged between PLC and frequency inverter to update input and output information. · The FB L_8200CtrlWord is used to select the control word to be transmitted as boolean control signals. (^ 3−15) · The FB L_8200DataControl is used for the actual process data exchange with the corresponding frequency inverter.

Function library Lenze8200Drive.lib Functions/function blocks 3.1 3.1 L_8200Parameter − Initialisation of codes L_8200Parameter − Initialisation of codes Function block With this FB you can parameterise up to 45 parameters (codes) in the frequency inverter.
Function library Lenze8200Drive.lib Functions/function blocks 3.1 L_8200Parameter − Initialisation of codes Concept I: Parameterisation through direct instructions in the FBs For this, use the FB L_8200Parameter as template and create a new function block in which the parameter data are selected by direct assignments. Note! Please observe that FB changes (e. g. new assignments) require a new compilation and program download to the PLC.

Function library Lenze8200Drive.lib Functions/function blocks 3.1 L_8200Parameter − Initialisation of codes Concept II: Parameterisation by means of codes If the FB outputs are assigned to user codes in the PLC, it is possible to select the corresponding frequency inverter parameters directly via the Parameter Monitor. Note! With this concept, it is possible to use an instance of the FBL_8200Parameter instead of a copy.
Function library Lenze8200Drive.lib Functions/function blocks 3.1 L_8200Parameter − Initialisation of codes Example II: Assignment of different parameters to a number of frequency inverters If you want to asssign different parameters to a number of frequency inverters, you need a corresponding number of FBs.

Function library Lenze8200Drive.lib Functions/function blocks 3.2 3.2 L_8200Initialization − Frequency inverter initialisation L_8200Initialization − Frequency inverter initialisation Function block This FB is used to initialise the frequency inverter with the parameters which were previously defined by an instance or copy of the FB L_8200Parameter. Note! The FB must be called cyclically because the data are internally transmitted to the frequency inverter via the FBL_ParWrite.
