Tool/software:
Hi,
We are trying to switch over from using Micronel blower "Radial Blower U65ML-024KT-5" to Boreasa blower "Miniature Centrifugal Blowers C60S1-xxPR-05-Lx Series". Here are our settings for the Micronel blower:
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_MotorParam1, 0x4A); // Driver output freq 50kHz, 12 "Rm" (motor phase resistance)
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_MotorParam2, 0x2B); // Driver output freq 50kHz, 12 "Rm" (motor phase resistance)
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_MotorParam3, 0x3A); // Driver output freq 50kHz, 12 "Rm" (motor phase resistance)
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt1, 0x00); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt2, 0x60); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt3, 0xC0); // Control Coeff: 11, Open Loop startup accel 000 (57 Hz/s*s), open loop start Accel 010 (19 Hz/s) // Was 0xFA default
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt4, 0xCB); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt5, 0xB0); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt6, 0x09); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt7, 0xB9); // Closed Loop Accel: 011 (0.77 Vcc/s), Stuck in closed loop: 1 (enabled) Deadtime: 9 // was 0xD9 default
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt8, 0x0D); //
i2c_write_register(DRV10983_I2C_ADDR, DRV10983_SysOpt9, 0x0C); //
When we try the new Boreasa blower with the existing settings, it barely starts to turn then stops. We tried every combination of the 3 wires/windings, but the behavior is always the same - start and stop.
Could the settings be causing the new blower to fail? Do you have suggestions about where to start looking?
Thanks.
