I see at store.mesanet.org H-bridge or

7I33 Quad Analog servo interface or Servomotor controller

There is only basic information about this davices.
I wonder, what Mesa has for making ServoDrive and what datasheet for it to how I can do servodrive for DC motors or AC motor?

Look at at the 7i39 and 8i20 too.

Thanks, Andypugh for your answer.
Does 8i20 servoamplifiers has any datasheets or manual? How they are controlled and connected?
And I don't anderstand from product description what is 8C20.

The 8I20/8C20 combination adds the features of analog input velocity and torque modes, step and direction mode, quadrature input mode, smart position control mode, and four isolated inputs and outputs.

Also 8C20 is something very small. It seems that it's a module that used to operate Power Mosfets or IGBTs.

It would be nice if somebody give some more technical information about this device.

In the store there is SoftDMC (firmware that converts any of our FPGA based I/O cards to a high performance DSP based motion control system). It seems that mesa has very interesting devices but how they could be embed.

I thought that I had replied to this.

I have never seen an 8C20.

My machines that use the 8i20 are controlled and commutated directly from HAL.
(With resolvers this can be very easy indeed, you just need to link the 7i49 resolver angle directly to the 8i20 rotor angle input)
For more complex situations, for example where the feedback pole count does not match the motor, for encoders, for Hall sensors, or when there is an offset, the "bldc" HAL component does the conversions.
