L6470 High Speed Issue
Posted on September 18, 2014 at 21:39Dear Motor IC Forum: I am using an L6470 to drive a stepper motor attached to a gearbox and am not able to achieve step rates greater than roughly 700 steps/sec with any microstepping setting. The motor gets loud...
u8 SVPWMEOCEvent(void) function in motor library V2.0
Posted on September 26, 2014 at 04:52 This routine to be performed inside the end of conversion ISR,from the function ,we can see that the ext. adc triggeringis disable when the motor state is RUN.So,how can we to trigrer AD conversion for the nex...
Bus Voltage Sensing Formula
Posted on September 28, 2014 at 16:21Gigi: I'm in the Bus Voltage Sensing parameter settings of Workbench when the input voltage is 24V, I am a divider resistor R1 = 51K R2=1K, how to calculate excuse me my Bus voltage sensing network parti...
ICS negative gain - how to?
Posted on September 27, 2014 at 14:10I am currently trying to deploy the STM32 foc library (v3.4 currently, v4.0 available not not tried yet) on a custom designed board. The motor does not startup, and I have tracked down the problem to a polarity m...
Torque limitation in PMSM FOC
Posted on September 24, 2014 at 10:26Hi,I'm controlling my PMSM at zero speed. While I'm trying to move its shaft I don't want my motor to generate its maximum torque to resist my movement but the limited one. Everything went fine with classic contr...
Efficient DC motor control
Posted on September 28, 2014 at 19:15Hi everyone,I have to develop a PMDC motor control. The main requirement is the maximum possible efficiency. Since I'm interested in a one way rotational direction, I thought that a low-side control (chopper) cou...
L6472 / L6474
Posted on August 27, 2013 at 10:05I am experiencing problem with the current regulation of the L6472. We made 2 series of boards, one was fitted with L6474s, the other one with L6472s. The board has 8 channels, supply voltage is 24V / 3.3V, timing p...
EVAL-L9942 interface problem
Posted on September 18, 2014 at 17:37Hello!I bought 3 Eval-L9942 boards. I connected supply voltage (5V). Enable (connect to 5V) and a step clock (5V. 100Hz). The VS supply is 12V.The motor i have connected does not move. All outputs are at 12V cons...
stepper motor ramp profile using timer 1 output compare
Posted on August 29, 2014 at 03:19timer 1 output compare to generate Step output for stepper motorI am using timer1 channel 1 as output compare, to generate a pulse of variable period.Desire output – In the beginning the output remain low for 4 ms(...
L6470 acceleration problem using sensor seek commands
Posted on August 21, 2014 at 22:41after performing a few sensor seeks using the ReleaseSW() and GoUntil() commands i have noticed that they do not use the same acceleration/deceleration. GoUntil() uses the programmed values, ReleaseSW() uses somethi...
