I’d appreciate any advice—I can’t find a solution.

This concerns parameterization of the G120C drive:

DI0 – Start Forward 1100 rpm

DI1 – Start Reverse 1100 rpm

DI1 + DI2 – Start Reverse 1600 rpm

DI3 – Emergency Stop

What’s been done:

Configured Constant Speed 1 & 2 and Forward/Reverse per the manual. The drive runs Forward but not Reverse.

Noticed that in Reverse, the drive doesn't detect the On/Off signal, since p840 (On/Off) is assigned to DI0, and I can’t assign p840 to both DI0 and DI1.

Also, Constant Speed parameters only allow selection with either (+) positive value or (–) negative value, preventing bidirectional operation.

Tried macros 12 and 17—no success.

Clearly, I’m missing something. Many thanks!

Many thanks ! I will have a G120C demo case tomorrow and I will try what you advised. I will let you know the result !

Appreciate

Good evening! 

First, many thanks for your ideas. Unfortunately, the above mentioned settings didn't allow me to run the drive, looked like p840 remains Low no matter what, if monitored in "Diagnostics"--> "Drive Enabled" via an IOP. 

The good news is the solution was found. I used p20062 "XOR 0 inputs" and assigned DI0 and DI1 to Input 0 and Input 1 accordingly. p840 to r20063 to be High when XOR output is High. Tested it and it works fine. 

Hello, I am trying to make a bidirectional and two-speed application. The motor worked at two speeds in the forward direction. However, I cannot run it in the reverse direction at all. And only one DI value can be assigned to P840.
