General
This document details the Modbus RTU memory mapping that is implemented in the Versidrive E2 drives,
detailing which addresses are used to read and write data to / from Versidrive E2 in a Modbus RTU network.
Note that for E2 drive, once the Modbus control/monitor is enabled (P-36>0), the Versibus network function
will be disabled, therefore disabling the Versipad E2 remote keypad and Versistick.
:
For control & monitoring of the drives the following parameters should be set correctly:
P-12 : (set to 3 for Modbus without ramp control or 4 for Modbus with ramp control )
P-36 : (communication address, baud rate and comms loss trip time)
P-15 (Analog and Digital input configuration)
For monitoring of the drives the following parameters should be set correctly:
P-36 : (communication address, baud rate and comms loss trip time)
P-15 (Analog and Digital input configuration)
Please see User Guide for more information on these parameter settings
The Fieldbus Gateways (Profibus, DeviceNet & Ethernet) also use the Modbus interface. In this case, the baud

The Fieldbus Gateways (Profibus, DeviceNet & Ethernet) also use the Modbus interface. In this case, the baud
rate must be set to 57.6kbps.
