Need to slow down gearing response on 7344 Motion Controller

[NickS_537]

I am using Flex Motion and Visual Basic with a 7344 motion controller. I am gearing a servo axis to an analog input signal, which works fine, but I want to slow down (delay) the response time of the gearing. That is, I would like changes on the analog input to show up on the axis position about 100ms later.

The gearing functions in FlexMotion will not let you set a time delay between the analog signal coming in and the response out to the servo. The 7344 controller handles all of this in hardware.

One option might be for you to use a DAQ card to sample the analog signal and then control the time when you send a corresponding signal to the motion board. Here you would be implementing the delay in software and the DAQ board would read in the original signal and then output an identical signal (just delayed) to the motion controller.
