Prototrak Plus Retrofit with Mesa 7i77 & 5i25 cards

andypugh, many thanks! Below is a description from the manual, I am not shore if I have answered the question. Also the link to manual. If you see the pics the old amps were on the inside of fan box, now on the out side, a "z" axes is on top, but looks like may need away work around to get power from capacitor PCB terminals, just looks 2 axes friendly.

""2.2.1 Single Phase (Brushed) Servo Drives
Brushed type servo drives are designed for use with permanent magnet brushed DC motors
(PMDC motors). The drive construction is basically as shown in Figure 2.3. PMDC motors have
a single winding (armature) on the rotor, and permanent magnets on the stator (no field
winding). Brushes and commutators maintain the optimum torque angle. The torque
generated by a PMDC motor is proportional to the current, giving it excellent dynamic control
capabilities in motion control systems.
Brushed drives can also be used to control current in other inductive loads such as voice coil
actuators, magnetic bearings, etc.""








My question is can I get away with using the push together spaded connectors or do I need to start anew and make one piece, for power to servo from amp. These are to be twisted,as you see in the pic, I have shrink wrap.

many thanks!!

andtpugh, many thanks, I like you say need the tools, I plan to make shore the connection is tight when pushed together, then shrink tube so when twisted it is all good.

EDIT: It appears the pin 1 can be used as 5v in; this can replace the separet power supply (connected to TB1) I currently have, correct?

many thanks to all!

andypugh, thanks for all your help! the 7i77 (TB1) location, top left. Pin 1 is the (servosystems.com/pdf/amc/12a8.pdf) link page 4 of 9, very top of the page. This is the link from you, I think.

many thanks!

Many thanks! to each of you who have help with this project!!

I am need to confirm leads. The pic is the end of the PCB with capacitor, the blue lead is to the right side of pic and I placed that on pin 5 on the P2 single connector (HIGH VOLTAGE DC Power Input) see this link: servosystems.com/pdf/amc/12a8.pdf.

I am attaching the white lead (the just to the left of center in the pic) to pin 4 the (POWER GND Power Ground (Common With Signal Ground))
I am attaching where the brown lead (hard to see, but is to the very far left) is to the pin 3 (POWER GND Power Ground (Common With Signal Ground)).

Now to P1 single connector: Pin 4 & Pin 5 go to 7I77 card DRV 0 & DRV 1.
Does this sound correct? Is there a way to confirm prior to powering up?





Many, many thanks in advance for help, it is warmly welcomed!

First is to power the power supply without hooking it up to the amp and use a volt meter to be sure where the positive out and ground are. Use an incandescent light bulb to load it and be sure. Then you can hook it up to P2, pin 4 and 5 of the amp accordingly.

I don't see any connector called DRV0 on the 7i77. The output from the 7i77 is from TB5 and called GND and AOUTx. See page 9, pdf 15 of the 7i77 manual. Those go to P1, pin 4 and 5 of the amp.

Best, Dan.
