Hi,
Motor[x].IdCmd represents the "direct current" component for commutating a motor. It is also referred to as the rotor magnetization current. It is required for direct microstepping.
Motor[x].IqCmd in the case of direct microstepping simply acts as a velocity command. It's proportional to velocity. It is usually very small, so does not contribute much to the total current applied to the motor.
Direct microstepping (open loop) is effectively locking the rotor into phase with the stator pole configuration throughout its revolution. IdCmd specifies the current applied as this occurs.
The total current command is the vectorial magnitude sqrt(IdCmd*IdCmd + IqCmd*IqCmd).
In closed-loop stepper, set IdCmd = 0 and the entire current command comes from IqCmd.
Do you have a detailled scheme like this image but in case of fully Closed-loop ?

Hello,
I have some questions concerned the direct current Motor[].IdCmd:
- What is the role of Motor[].IdCmd ?
- What is its impact in case of Open-loop or Close-loop ?
- As I know, the command "out" injects the percent of the current Motor[].MaxDac. In the attached image, just Open-loop part, where this "out" current is injected ? What is the impact of Motor[].IdCmd in this case ?
- In the same image, what's the use of Motor[].IdCmd in case of Close-loop because normally the Motor[].IqCmd adjusts all.
Thanks

Hi,
I am not familiar with a "boucle". Can you post more information on this mechanism/device?
Sorry, I mean double loop

Hi everyone,
Do you know how to configure a double boucle ? Thanks

Hi everybody,
Do you know how to configure a BISS Encoder ? I'm using Acc84B board.
Thanks

Hi everyone,
Do you know how to configure a Resolver McLennan M543Cl500L integrated with servomotor DC same brand ? This motor is piloted by a external driver (McLennan). The motor is piloted by analog signal. It has double loop: a integrated Resolver and a incremental encoder Renishaw RESR RGH20F30J02A.
Thanks

Hi everyone,
Do you know how to configure a picomotor NewFocus 8301 in open loop ? This picomotor is piloted by puls/dir signal via the NewFocus Driver and use incremental encoder.
Thanks

What's nb_counts_per_commutation in your file and how we can find it ?
