Change clock frequency in PCI 7334

[paola]

Hi ,

   I'm using a PCI 7334 stepper motor controller. The default clock is 10 KHz, but I would like to reduce it to 100 Hz or less.

I'm using LabView 8 and  the example .vi like 

One-Axis Find Reference with Status Monitor.vi or

Simple One-Axis Move.vi

I can't find how to change the clock frequency. Anybody can help ?

Many thanks.

Hi, I think you have to change the velocity using Load velocity function. You can find an example in the One Axis.llb > One-Axis Move (Accel- max Vel - Decel).vi in which is used Load Velocity in RPM.flx. If you want to specify Steps/sec you have to use the Load Velocity.flx function (as you can see from the help the default value is 10000steps/s). Best regards AmbuA
