LMV Series

Modbus settings on the LMV3

To be able to edit the Modbus parameters on the LMV3, at least the service level password must be
entered via the AZL2... / ACS410.

Slave address

Setting the slave address is made via parameter 145. Any address from 1...247 can be used. The slave
address is stored in nonvolatile memory in the LMV3. Changes to parameter 145 can only be made via
the LMV3..., not via Modbus.
Parameter Default
145 1

Baud rate of Modbus interface

Setting the Baud rate is made via parameter 146. This parameter specifies the transmission rate for the
Modbus interface. The Baud rate is stored in nonvolatile memory in the LMV3. Changes to parameter
146 can only be made via the LMV3..., not via Modbus.
Parameter Default
146 1

Parity of Modbus interface

Setting the parity is made via parameter 147. The parity is stored in nonvolatile memory in the LMV3.
Changes to parameter 147 can only be made via the LMV3..., not via Modbus.
Parameter Default
147 0
