Dear sir

We are using two smart motors (478T)for our research purpose. we have connected two servo motors through RS232 port to computer and used daisy chain connection through RS485 wiring.
It was working fine for a long time with the program mentioned below.
Now i am experiencing a serious problem
After motor-1 moved to the first target position (p=20000) the process is stopping and when we try to communicate to the
motor through SMI it indicates an error like this.

"A response was expected from a motor on the port "Com1",but was not received.Please check the power, connections
and port setting. Also please make sure the motor address is correct. The motor address may be changed by a
user program after the motor is reset or the user program is run."

,I verified the connections. But can't resolve the issue.

Kindly help us to resolve this issue.

The error response is from the RS232 connection on the motor. It could be due to a USB to RS232 adapter or an intermittant wiring issue. Please contact our tech support at 888-356-0357 if you continue to have problems.

You can send that information to service@animatics.com and they will be able to send you the factory settings file. I cannot post them on the forum.

Does the SMI2 software show that you have an ADB error? I haven't been able to find the file for your serial number.

You may need to use the Communication Lockup Wizard in the SMI2 software. The motor you have could have a program that changed communications parameters. It could also be using PRINT statements.
The Lockup Wizard is on the Communication menu.
