Issue:
How do I setup the Altivar Process Drive to communicate over Modbus over Ethernet (TCP)?

Product Line:
Altivar Process Drive (ATV630, ATV930, ATV650, ATV950, ATV660, ATV960, ATV680, ATV980)

Environment:
All serial numbers

Cause:
Need to connect to the drive and communicate over Modbus

Resolution:

Setting up Modbus TCP on the Drive
EDS Files

• Download and import Modbus Ethernet EDS files
  • ​Ethernet Embedded: https://www.se.com/ww/en/download/document/ATV600_Ethernet_Embedded_EDS/
  • Ethernet Embedded: https://www.se.com/ww/en/download/document/ATV900_Ethernet_Embedded_EDS/

Basic Settings

• Program Communication Settings:
  • ​[Communication] [Comm parameters] [Ethernet Embd] Config submenu
    • [IP Mode Ether. Embd]
    • [IP address]
    • [Mask]
    • [Gateway]
  • ​​​Setting up a Modbus Address
    • [Communication] [Comm parameters] [Modbus SL] [Modbus Fieldbus]
      • ​[Modbus Address]
      • [Bd.RateModbus]
      • [Modbus Format]
      • [Modbus Timeout]​​​
  • • To read/write directly to individual 4x registers you will need to set a Modbus Address in the drive.
      • The Modbus Address should match your Unit ID on PLC (Typically that is Unit ID of 1)
    • When using the IO scanner input/output tables you will need to use a Unit ID of 255
      • Set [Modbus Address] to 0
      • Configure IO Scanner Input/Output Table

• Remember to Power Cycle the Drive after any communication changes
• Programming Command Settings:
  • [Complete settings] [Command and Reference]
    • ​For command speed from Network, program:
      • [Ref Freq 1 Config] Fr1 - Set to [Embedded Ethernet] Eth
      • [Ref 1B switching] rCb - Set to [Ref Freq Channel 1] Fr1
      • [Control Mode] CHCF - Set to [Not separ.] SIM

• Program Communication Settings (from SoMove)
  • ​​[Parameters List] [Fieldbus] [Modbus TCP/Ethernt IP]
  • Configure Drive Protocol (ATV900)
    • Ethernet Protocol - Set to Modbus TCP

Commanding the Drive

• Using IO Profile characteristics:
  • [Complete Settings] [Command and Reference] [Control Mode] - Set to "IO"
  • Command Word - 8501
  • 16 bit word (Bit 0, 1, 2..... 15)
  • Start/Stop must turn on bit 0 (first bit)
    • Write a 1 to start
    • Write a 0 to stop
  • Bit 1 to 15 are assignable to other drive functions like Fault Reset
  • Speed Reference
  • Speed Reference Word:
    • 8502 (Hz) and 8602 (rpm)
• Using CIA402 (DriveCom Profile) characteristics:
  • Works with all assemblies
  • [Control Mode] to [Not separ.] or [Separate]
  • Command Word - 8501
  • No 16 bit word
  • Start/Stop​
    • Drive will display nSt on top left corner.
    • A sequence of values must be written to the drive:
      • 6, 7 and 15 decimal values
      • Toggle between 7 and 15 to start and stop
  • Speed Reference
    • Speed Reference Word:
      • 8502 (Hz) and 8602 (rpm)
