L6480 - first move after STBY/RESET sometimes fails
Posted on October 08, 2014 at 14:53Hello.We are using the L6480 with a Fulling FL86ST67 motor driving a drum sorter.As a security measure, there is a light curtain asserting the STBY/RESET pin for every object entering. The first move (by 200 steps)...
L6470H discovery Issues on two systems
Posted on October 02, 2014 at 22:29I am attempting to run the L6470H discovery kit with the dspin software from a machine with windows xp on it. I was previously able to run it from another machine with xp, I installed the same files but cannot conn...
L6472 Spurious Over Current
Posted on September 26, 2014 at 22:05I'm having a similar issue as someone else posted last year. We had problems with overheating of the IC, so I increased the slew rate and that helped. But now, we're seeing random over-currents and I am wondering...
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...
