Connect User's MOTOR (Not attached motor)

The board and initial firmware are set according to the attached motor. When using a user's motor, it is
necessary to adjust setting parameters such as drive current and lead angle setting and so on. Also, change the
hardware and software settings.
Below are the parts that need to be changed.
Shunt resistor(R65) -- change according to the amount of power supply current (initial value 100mΩ)
■
Phase current detection resistors(R83,R88,R95)
■
Modified to fit the amount of phase current of the motor (Initial 200mΩ)
●
Phase current detection bleeder resistors (R82,R87,R94)
■
Adjusting the current flowing to the phase current detection resistors
●
Also, when connecting a motor with encoder, change the following settings.
AMP1 activation resistor (R79, R80, R85 R92, R96, R18, R29) -- short (initial: not installed)
■
LED1, LED2 current limiting resistors (R56, R57) -- Remove (initially: 3.3kΩ resistor mounting)
■
Hall IC thermistor activation resistor (R20) -- Remove
■
Note.1 In the worst case, damage may occur depending on the motor specifications and drive conditions. If necessary, change the
multiplier of the protection resistor or diode. Check the data sheet for details.
Note.2 LED1 and LED2 cannot be used when connecting an encoder to P00 and P01.
