Table 3.
Hardware configuration for an AC induction motor
This section describes the procedure for operating the STM8/128-MCKIT with an AC
induction motor. You must change the default settings that are present on the STM8
evaluation board and on the power board when you receive the STM8/128-MCKIT starter kit
because they are intended for a PMSM motor. When you are running the AC induction
motor, follow these steps:
1.

6.
7.
8.
9.
After re-programming the STM8S microcontroller with the ACIM motor control firmware, the
STM8/128-EVAL is now ready to run with your AC induction motor.
Before supplying the board, double check proper connections, make sure that there are no
metal parts on, below or around the PCB and that there are no undesired earth/ground
loops due to measuring equipment such as an oscilloscope.

Remove the BLDC daughterboard (MB843) from the STM8/128-EVAL evaluation board
(MB631).
Remove the adapter board (MB844) from the power board (MB459B).
Change the jumpers on the power board (MB459B) to the settings required for running
with an AC induction motor. Refer to
an AC induction motor
MB459B power board user manual for the location of the jumpers on the board.
If the peak value of the motor phase current should be greater than 3 ampere, replace
the R4 shunt resistor on the power board (MB459B) by the 0.1 ohm resistor included in
the bag delivered with the kit.
Verify that the jumpers on the STM8/128-EVAL evaluation board (MB631) are in their
default position. Refer to
motor
board user manual for the location of jumpers on the board.
Disconnect the PMSM motor from the power board's MOTOR connectors (J5 and J8).
The power board (MB459B), the STM8/128-EVAL evaluation board (MB631), and the
provided PMSM motor are already assembled together over a metal support when you
receive the kit.
Connect your AC induction motor to the power board by connecting the three phases to
the J5 connector, and the tachometer cables to the J6 connector.
Power up STM8/128-EVAL evaluation board with auxiliary power supply block TR30R.
Power up the power board by connecting the output terminals of your DC power supply
to the MAINS connector (J3). The provided voltage must not be higher than 42 V DC or
32 Veff AC (GND recommended).
