3.3.3 Output Connectors: J2, J4, FASTONS (J5, J7, J8)
Power output to the motor is located on connectors J2, J4 and
FASTONS (J5, J7, J8). Pin assignments are described in
Table 3-2 .
FASTON type connectors are labelled with PhA (connector J8) for phase
A, PhB (J7) for phase B, and PhC (J5) for phase C. Phase order is
identical for all three connectors. Note that wire color may vary with
different motor types.
3.3.4 Jumpers and Switch/Push Button: M0, M1, PWM, SW1
The jumper groups M0 (JP2) and M1 (JP3) are used to select the
operating mode of the SMOS gate driver (see
Table 3-3 ). For the truth
table of the driver, see its data sheet.
For selection of the PWM signal brought to the gate driver, the 140A01
board version uses the SW1 rotary switch and the 140A02 version uses
the PWM (JP5) jumper group and RESET (SW1) push button. Both
solutions have the same behavior (see
Table 3-4 for an explanation).
When one PWM signal is sent from the controller board to the motor
board through the UNI-3 interface, the SMOS driver must multiplex it
between the three phases according to the mode defined by M0 and M1.
The mode selection is not needed when six PWM signals are generated.
