Lenze ESVZAR0 RS-485 - Manual (Page 2)

This documentation applies to the ESVZAR0 RS-485/Modbus communications option for the SMVector inverter models
up to 10HP. This documentation should be used in conjunction with the SMVector Operating Instructions (Document
SV01) that shipped with the drive. These documents should be read in their entirety as they contain important technical
data and describe the installation and operation of the drive and this option.
WARNING!
The information in this document is based on RS-485 Modbus Communication Module
software version 1.01. If a future revision of software contains differences in the register
numbering or register definitions, drive operation could be seriously affected. If drive
parameter P494 does not display
1.01, 1.10 or 1.30, then writing to any drive register
over the Modbus® network MUST NOT BE ATTEMPTED as it would have the potential
for unexpected consequences potentially resulting in damage to the equipment or
harm to personnel. Future releases of module software require that the appropriate
documentation be used for implementation.
