The feedforward control block diagram in the official data is as follows: However, the calculation result in FF_VqdffComputation is different, taking ΔUq as an example.ΔUq = (Ke + Ld*Id)*2*pi*p*fr + UqThe code in FF_VqdffComputation is as follows:/*q...
STPM32 is used for an e-meter application. Idea is to use 2-pin UART connection, isolate only the RX and TX with optocouplers and not to use the SYN and SCS for reset.According to datasheet on page 68 the remote reset can be performed in two ways:· ...
I'm searching for a pin to pin replacement for the L7985A with same pinout, same (or better) characteristics, with a lower quiescent current. Any help will be very appreciated. Thanks.
Hello. I try tu adjust the value of shunt resistor in STPM10 electronic circuit.First I placed one 0.5mOhm resistor value, and I watched that 40W lamps meassurement is not very exact. Maybe I should to increase this value. But I have read that maxim...
I have a problem with triac BTA06-600B, when I try to power off some LED lamps they start flickering. I use triac to manage the main power (220V 50Hz), if the load is a traditional, halogen or cfl lamp all works fine. I tried to unmount the snubber c...
I made a push-pull converter using sg3525a. my problem is the output voltage will drop when I connecting 100-watt load or more.input voltage is 24 volt and the output is 350 volt. the frequency is 100khz. using MOSFET irfp4568. using RC snubber with ...
Hi All!Doing a project where I need the L6470 to run a Nema-17 motor with 100:1 gearing. The motor is rated for 1.7A. The power supply is set for 24V and 1.7A. However, I cannot get the driver to run the motor at its rated speed. It should be able to...
Hi All; I would like to calculate CT. I have formula below.I factor = VREF / (AI * CALIB_I * DPOW * KSI * KINT ) VREF = 1.18 from datasheet AI = 16 from datasheet CALIB_i = 0.875 from datasheet DPOW = removed KSI = Rshut = 0.05 ohm when I calcurat...
I m using L6470 which is working fine without load, but when load is applied the motor stuck. Which parameter i should consider for it?also how to reduce stepper motor noise?My current configuration are like thiswrite_buffer[0]=CMD_SETPARAM |REG_MAX_...
