Motor control
STR910-EVAL board supports induction motor control via a 34-pin connector CN1, which
provides all required control and feedback signals to and from a motor power-drive board.
Available signals on this connector include emergency stop, motor speed, 3-phase motor
current, bus voltage, Heatsink temperature from the motor drive board and 6 channels of
PWM control signals going to the motor drive circuit.
Emergency stop, motor current sampling and motor speed detection are enabled by setting
jumpers JP16, JP7 and JP8.
The potentiometer (RV2) can be used to control motor speed when JP1 is configured to
connect RV2 to P46 of the STR91xF. See
Table 7.
Jumpers JP18, JP19, JP21, JP22 and JP23 enable signals for UART1 with full modem control

UART1 DCD signal is enabled when JP18 is fitted.
Default setting: Fitted
UART1 DSR signal is enabled when JP19 is fitted.
Default setting: Fitted
UART1 CTS signal is enabled when JP21 is fitted.
Default setting: Fitted
UART1 RI signal is enabled when JP22 is fitted.
Default setting: Fitted
UART1 RTS signal is enabled when JP23 is fitted.
Default setting: Fitted
JP16 enables the emergency stop function on P67 of the motor control connector CN1.
P67 of the STR91xF is shared by both motor control and ETM trace support.
P67 is used for motor control emergency stop detection when
JP16 (MC or ETM on silk-screen) is set as shown on the right:
(default setting)
P67 is used for external trigger of ETM tracing when JP16 is set
as shown on the right:
Motor current sampling operation is enabled when JP7 is fitted (P40 connected to
P43). The I/O pins P40 and P43 are disconnected and can be used by a daughter
board when JP7 is not fitted.
Default setting: Fitted
