With
LabView 7 motion control and the PCI-7344 cart I would like control two
EC-Servomotors in combination with the Encoder HEDL 9140 and the Servo
amplifier DES50/5 form Maxon.
In one test
I work with the program
Motion Control with USB Joystick
(http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=CDF9D8F70BF633BBE034080020E74861)
but the program doesn´t work proper.
- After few
seconds the motor runs out of control e.g. I move the Joystick to the
right and the motor spins to the left with full speed doesn´t detect any
softwarelimts set before in Max.
- Another
phenomena is that sometimes after a movement and a stop a new movement is
not possible in the other direction until a short move in the direction
before
With an additional “Wait until next ms” > 80ms in the “While loop”
the problems appear with a slower rate but still exists and with the disadvantage
of a slower response time.
From NI I get the information that the program runs in their system
without a time delay.
Why doesn´t it function in my system?
-------
I have to use ActiveX to get the Force/Torque information from the ISA F/T-Sensor.
Do you know how fast the communication between LabView and ActiveX is?
