how to establish a motion ocntrol in current mode using 7344

[Gops]

hi
I am using an external drive to run the motor. The drive has both hall current sensor feedback and encoder feedback. The drive is capable of working on both current and velocity mode.

What are settings that has to be done on the 7344 to run the motor in current mode (torque mode).
What should be my primary feedback? Do I need to connect the encoder feedback to the motion controller.

Hello,

National Instruments motion controllers run, by default, on current (torque) mode. You need to input your encoder feedback as your primary feedback source and the hall sensor as the secondary feedback (in case you decide to run the motor in velocity mode in the future. otherwise you don't need to connect the hall sensor).
Hope this helps!

Hi
I have few doubts;
1. Is the encoder required for velocity mode or current mode.
2. In current mode of operation we need the hall sensor, how is used in the velocity mode of operation.

Hello,

Motion control applications are classified primarily as position control and velocity control. They both use current to control the motor. Encoders are used as primary feedback for position control and transducers (such as torque sensors, LVDTs, hall effect sensors, etc.) are usually used as secondary feedback for velocity control.
If you need more information on these check out the motion control tutorials on developer zone at http://zone.ni.com/devzone/devzone.nsf/webproducts/69771825ae23e98e86256786000bea02
