Initially, thanks for your attention. Sorry for single diagram, but only got this by now ...
As nominal current or work current, this will be in the near average
(30A)
, but in test the peak
, reached 90A, believe me ... In normal running will be (30A)...
--------------------------------------------------------------------------------------------------------------------
After the first test, yes I am developing one board with PIC microcontroller for PWM control, lights control, sound control and more... In this moment I have test this power circuit...
--------------------------------------------------------------------------------------------------------------------
The motor used is this: **broken link removed**
--------------------------------------------------------------------------------------------------------------------
Well, the voltages on the concector "CN5" are:
1 = (+5v) logical, from microcontroller board " NOT EXISTENT NOW".
2 = (Hin 1) connected in (Lin 2) with wire-up for test...
3 = (Lin 1) connected in (Hin 2) with wire-up too...
4 = (SD1 and SD2) shoot down pin IC1 and IC2, put in gnd level for test...
5 = (GND) logical, from microcontroller board " NOT EXISTENT NOW".
6 = (Hin 2)...
7 = (Lin 2)...
8 = (OUT I -Sense) Future current sensor... NOT Implemented now.
9 = (ON/OFF) Return to activate 30A relays.
10 = (OUT +BAT) Used to connect switch ON / OFF to 30A relays...
This mode, I have connected the BATTERY (+ and -), ON/OFF power switch, (+5v and gnd) logical from bench power supply (test) and finally the HH switch for reversal test...
The pins Hin and Lin inversely connected , have your logical levels reversed acting in the test switch (H-H).
In this moment, the right side not respond with reverse of test switch (H-H).
But, the left side is OK... When the logic level on the inputs is changed, the outputs (Ho and Lo) is changed too.
--------------------------------------------------------------------------------------------------------------------
I don't put FAST DIODES under the IRFs transistors to reduce the size of board.
---------------------------------------------------------------------------------------------------------------------
The reason for the three relays is that the circuit under test already consumed (90A) """
peak
""" ... And one commun switch would be too large ... With this argument, I use a small switch in (ON/OFF) circuit ...
-------------------------------------------------------------------------------------------------------------------
My programmer friend "Rubens" make programming the logic part ...
For me, is left to do all the physical "hardware" ...
The control board will provide logic control for H-Bridge and PWM... Respecting all timing necessary...
In this moment I need to know if it is possible to connect the circuit according to the scheme for testing rotating and reversing?
Just changing the logic levels at the inputs?
Or will I need pulsing signals in these entries?

Again, thanks for your attention, sorry a little explanation for the circuit.
Receive all my respect and gratitude.
