The GS4 drive supports several types of communication:
• Serial Modbus (built-in RS-485 port)
• Serial BACnet (built-in RS-485 port)
• Modbus TCP (optional GS4-CM-MODTCP card)
• EtherNet/IP (optional GS4-CM-ENETIP card)
Note: Only one serial protocol can be used at a time. Only one Ethernet option card can be
installed at a time (You can have serial Modbus and one Ethernet card running at the same time).

This section will point out the "need to know" details of how to connect to your PLC to a GS4 drive.
Detailed serial BACnet information can be found in Chapter 5: Communications.
The first thing to do with the GS4 drive after the basic wiring, is to set up the motor information
and protection features. Detailed information on drive setup can be found in Chapter 4:
Parameters. The minimal set of parameters that need to be adjusted can be found in the
QuickStart Menu. After powering up the drive and ensuring that your E-stop and/or STO input
work, press MENU on the keypad. Scroll down to 7: QuickStart and press ENTER. The options
inside the QuickStart menu provide the bare essentials to properly set up the drive so that it will
run and protect the motor. With the cursor located at 1: Keypad, press Enter. Enter information
into the eight parameters listed under the 1: Keypad setting. For more information, see Chapter 3:
Keypad Operation and QuickStart.
NOTE: If you have changed many parameters and cannot get your drive to function the way
you want, go to Parameter P9.08 Parameter Reset and enter a value of 9 or 10. This will reset
your drive to its factory default settings. Then go to the QuickStart Menu and enter the eight
parameters listed under "Keypad."
Your drive should now be ready to function from the keypad and be able to properly protect the
motor from an overload. From the main screen, press LOCAL. The drive should start and stop by
pressing the RUN and STOP keys. The output speed can be changed by pressing ENTER when the
cursor is beside the "F" setting (frequency). If the drive doesn't run, check all power and control
wiring, especially wiring associated with STO (E-Stop).

Serial Modbus connections over RS485 can be made to the GS4 drive using two different methods.
The GS4 drive is equipped with two RJ45 ports on the main control board. Using these ports,
the GS4 drive can be connected to an RS485 network using standard Ethernet cables. For longer
cable runs, use the SG+, SG- and SGND terminals, also located on the main control board, with
shielded cable. See Chapter 2 for detailed wiring specifications and Chapter 5 for detailed Modbus
information.
