Commissioning Before initial switch-on ________________________________________________________________ 6 Commissioning During commissioning, system-related data such as motor parameters, operating parameters, responses, and parameters for fieldbus communication are defined for the drive. For Lenze devices, this is done via the codes. The codes of the drive and communication are saved non-volatilely as a data set in the memory module.
Commissioning How to configure the host (master) ________________________________________________________________ 6.2 How to configure the host (master) For communication with the inverter, the host (master) must be configured first. Defining the user data length • The AS-Interface Communication Unit supports the configuration of max. 8 process data words (max. 64 bytes). • The user data length is defined during the initialisation phase of the master.
Commissioning Settings for AS-i communication in the »Engineer« ________________________________________________________________ 6.3 Settings for AS-i communication in the »Engineer« 6.3.1 Addressing the AS-i slaves Addressing is usually carried out automatically via the master or an external addressing unit. The AS-Interface Communication Unit uses two slaves (see AS-i concept of the Communication Unit ( 33)) which must be initialised with unique addresses.
Commissioning Settings for AS-i communication in the »Engineer« ________________________________________________________________ 6.3.2 All parameters for setting the AS-i communication All parameters for setting the AS-i communication can be found in the »Engineer« on the "All parameters" tab. Save the changed settings with the device command C00002/11 (save all parameter sets).
Commissioning Initial switch-on ________________________________________________________________ 6.4 Initial switch-on Establishing communication • To establish a communication, the Inverter Drive must be supplied with mains voltage. • For AS-i communication, the Communication Unit has to be supplied with voltage. If this is not the case, the error message "CE04: MCI communication error" (error no. 01.0127.00002) is output.
Data transfer AS-i messages ________________________________________________________________ 7 Data transfer The AS-Interface transmits parameter data, configuration data, diagnostic data, alarm messages and process data between the host (master) and the inverters (slaves) participating in the fieldbus. Depending on their time-critical nature, the data are transmitted via different communication channels. The bus access method of the AS-Interface is a master-slave method with cyclic polling.
Data transfer AS-i messages ________________________________________________________________ Structure of the master call Structure in the standard addressing mode for up to 31 slaves: ST SB Address Information PB EB 1 bit 1 bit 5 bits 5 bits 1 bit 1 bit Structure in the advanced addressing mode for up to 62 slaves: ST SB Address 1 bit 1 bit 5 bits Information 1 bit Select bit 3 bits PB EB 1 bit 1 bit Bit field Description ST The start bit marks the start of the master call.
Data transfer AS-i cycle ________________________________________________________________ 7.2 AS-i cycle The complete AS-i cycle consists of: • AS-i messages Max. 31 messages (sum of the standard slaves connected to the network or the maximum of A and B slaves) • 1 management call Consists of a parameter exchange or a command to a slave and an optional response.
Data transfer Synchronisation ________________________________________________________________ 7.3 Synchronisation The synchronisation serves to read in or output all input and output data exactly at the same time and independent of the slave address. The jitter of the outputs can be reduced from ± 2.5 ms to ± 154 μs. In a standard data exchange, the outputs of each slave that receives a data call from the master are updated immediately and the input information are read in.
Data transfer AS-i concept of the Communication Unit ________________________________________________________________ 7.4 AS-i concept of the Communication Unit The AS-Interface Communication Unit supports the following device profiles: AS-i profile Slave Data transmission Data / parameter bits 7.A.

Data transfer Data transmission slave 2 (AS-i profile 7.A.E) ________________________________________________________________ Accessing the parameter bits Parameter bits P0 ... P3 provide diagnostic information to the master for slave 2. Here, P0 ... P2 define whether a status query of code C00150 or an error/warning diagnostics is returned as slave response to the master. The values of P0 ... P3 are transmitted to the master via the "Write_Parameter" command.
Process data transfer ________________________________________________________________ 8 Process data transfer • Process data are transmitted via the process data channel. • The process data serve to control the inverter. • The transmission of process data is time-critical. • Process data are cyclically transferred between the master and the slaves participating in the fieldbus (continuous exchange of current input and output data). • The master can directly access the process data.
Process data transfer Accessing process data / PDO mapping ________________________________________________________________ 8.1 Accessing process data / PDO mapping Process data are transferred via the MCI/CAN interface. • The process data is accessed via the LP_Network_In and LP_Network_Out port blocks. • Up to 8 words (16 bits/word) per direction can be exchanged. • The port/function blocks of the process data objects (PDO) are interconnected via the Lenze »Engineer«.
Process data transfer Port interconnection of process data objects (PDO) ________________________________________________________________ 8.2 Port interconnection of process data objects (PDO) How to configure the port interconnection in the »Engineer«: 1. Go to the Application parameters tab to make the default setting of the I/O configuration. Select the "Network (ASi)" control mode (C00007). 2. The Process data objects tab of the AS-i interface displays the preset I/O configuration.
Process data transfer Port interconnection of process data objects (PDO) ________________________________________________________________ 3. Open the "Assignment Signal --> Function Block" dialog window using the buttons. Here, tick ( ) the signals that are sent from the PLC (AS-i master) to the inverter. 4. Confirm the selection with OK. Lenze · Decentralised frequency inverter 8400 motec (AS-Interface option) · EDS84DMOTASI EN 4.
Process data transfer Port interconnection of process data objects (PDO) ________________________________________________________________ 5. The codes C00620/21, C00620/24, C00621/30 and C00621/31 serve to select the signals that are sent from the inverter to the PLC (AS-i master). 6. Use code C00002 to execute the command "11: Save all parameter sets". The changed settings are activated and saved safe against mains failure.
Parameter data transfer ________________________________________________________________ 9 Parameter data transfer • Parameter data are acyclically transmitted via the parameter data channel. • The parameter data channel provides access to all Lenze codes. • In general, the transmission of parameter data is not time-critical. • Parameter data are, for instance, operating parameters, diagnostic information, and motor data.
