I have a wire saw machine that runs with a Telematique PLC-ABL1REM24042 and a Yaskawa F7 drive. The YASKAWA F7 drive does not respond to the PLC's command. I ran all kind of testing and have not been able to figure out the problem. Also the HMI does not record or register the command. I notice that the rotation speed is register as 0.0 so is the activation rotation drive. For some reason I am unable to change the numbers on the HMI. Can any one help me ascertain the problem? I am not an engineer but I have working knowledge of machinery.

I thank you, in advance, for your assistance.

Ramstone.

 

This is one of those things that could be about 50 different things.

A common situation is a hard wired interlock that is not being made.
Could also be the PLC is sending a zero speed signal to the drive for some reason.

Thank you Bob.I truly appreciate your response.

 

Please check your part number for the PLC. The part number that you have provided appears to be a power supply. How is the drive connected to to the PLC (Serial or direct I/O connection)? What is the programming package used with the PLC?
