Issue:
How do I send a start/stop and a speed command to the Altivar Process Drive over Ethernet (Embedded) protocol?

Product Line:
Altivar Process Drive

Environment:
All serial numbers for Altivar Process Drive

Cause:
N/A

Resolution:

Unit ID: 1

Command:
DRIVECOM (CiA402 profile)
You profile is set to seperate or not seperate and you need to command the drive.  Your Unit ID is set to 1


On the Drive,
[Communication] [Comm parameters] [Modbus SL] [Modbus Fieldbus]
- Set Modbus Address to 1

[Complete settings] [Command and Reference] [Control Mode] CHCF
- Set to [Not Separ.] or [Seperate Mode]

Command Word Register: 8501
To start the drive under DRIVECOM profile, you will need to write a decimal value of 6, 7, and 15 directly to the command word 8501
Toggling 7 and 15 will either stop or start the drive.


I/O Profile
To profile is set to IO Profile and your Unit ID is set to 1

On the Drive,
[Communication] [Comm parameters] [Modbus SL] [Modbus Fieldbus]
- Set Modbus Address to 1

[Complete settings] [Command and Reference] [Control Mode] CHCF
- Set to [I/O profile]

Command Word Register: 8501 (16 bit register)
Reference Frequency: 8502 (0.1hz) or 8602 (1 rpm)
To start the drive under I/O Profile profile you will need to toggle off and on bit 0. 
After Command is sent a speed reference is given by writing a decimal value in units of 0.1Hz to the register 8502 or 8602 in units of 1 rpm.
[Nominal Motor Speed] value will have to be set correctly in the [Motor parameters] Menu.



Unit ID: 255

With the Unit ID of 255 you do not need to set your modbus address (leave it set at 0)
You will just need to turn on IO scanner through Somove
The drive will automatically look at the IO scanner input/output table. 

Please reference FAQ - "How do I enable and configure the I/O Scanner on the Altivar Process Drive?"
