2 Product Overview
2 Product Overview
About This Product
The SI-EM3 option provides a communications connection between the drive and a Modbus TCP/IP network. The option
connects the drive to an Modbus TCP/IP network and facilitates the exchange of data.
This manual explains the handling, installation and specifications of this product.
Modbus TCP/IP is a communications link to connect industrial devices (e.g., smart motor controllers, operator interfaces,
and variable frequency drives) as well as control devices (e.g., programmable controllers and computers) to a network.
Modbus TCP/IP is a simple, networking solution that reduces the cost and time to wire and install factory automation
devices while providing interchangeability of like components from multiple vendors.
Modbus TCP/IP is an open device network standard.
By installing the option to a drive, it is possible to do the following from a Modbus TCP/IP master device:
• operate the drive
• monitor the operation status of the drive
• change parameter settings.
Applicable Models
The option can be used with the drive models in Table 1.

Electrical Shock Hazard
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Disconnect all power to the drive, wait at least five minutes after all indicators are off, measure the DC bus voltage to
confirm safe level, and check for unsafe voltages before servicing to prevent electric shock. The internal capacitor
remains charged even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus
voltage is below 50 Vdc.
WARNING
