motor, amp, compensation board settings.

jan 08

    The specs and settings for the motor, amp, and compenstation boards are listed below. They are taken from jon hagens memo: bds4.wp6.
We have 3 separate configurations:
  1. azimuth (604-a motor), modified compBrd
  2. dome, ch (606A motor), modified compBrd
  3. tiedowns, rotary floor (606A motor), generic comp board)
The differences in the az, dome comp baords have to do with the motor (max speed,etc).
Jons compensation board notes:
    The bds4 has an internal compensation board. Kollmorgen supplies the amplifier with a compensation board tailored for a given motor model. If a different motor is used, the appropriate compensation board must be installed in the amplifier. One might suspect that , to implement  a velocity loop, the compensation would also depend on the nature of the load - inertia, friction, bias, etc. Indeed, in addition to the generic compensation board for each motor, Kollmorgen has furnished dozens or hundreds of custom boards. Our tie-down and rotary floor drive system use generic compensation boards.  The elevation and azimuth drive system have compensation boards modified by vertex. Vertex made two changes to the generic boards:
  1. They disconnected the velocity feedback by removing R4, R13, and C12.
  2. Instead of lowering the dc gain by simply grounding the torque hold input (pin 14 on connector C1) they permanently lowered the dc gain by shunting a 20K resistor across the op amp. They did this by installing a short (jumper) in place of C2, forcing R9 to bridge the op amp. On the B-604A comp card, R9 was already 20k. On the B-606A comp card, they changed R9 from 14K to 20K.
