Controle nema 23 brake

droftarts

@Amagatth No, you need a separate 24V supply. PWM (Pulse Width Modulation) does not vary voltage; it just pulses 48V. It will burn out your brake solenoid, or will make your brake turn on and off all the time.

@droftarts

chek V parameter

droftarts

@Amagatth The key word in the V parameter description is average. The V parameter uses PWM to average brake voltage. It will still be 48V, but pulsed so that half the time it is on, and half off. This isn't the same thing as actually reducing the voltage to 24V. You need to check that the brake solenoid can handle this, rather than requiring 24V.

@Amagatth ok so i think i go put a 24 v psu with a relay its faster haha

Amagatth

Hi , i set up my brake but i have a pb, when i make a m17 my relay go on i have 24V for my brake , but when i make m18 24v stay on , anyone have a solution plz ?

droftarts

@Amagatth Are you using M569.7 to define the brake? Are both the brake and motor driver connected to the same Duet board? Post your config.g and version of RRF you are using. Also check your config.g is working correctly by sending M98 P"config.g"

Ian

Amagatth

@droftarts attached my config. G i have 4 Z motor with all brake connect to out 9 m98p'config.g" work fine and i run on 3.5.2 on the 2 board config.g

@droftarts Hey how are you ? you see anything wrong ?

droftarts

@Amagatth If the brakes are still not working correctly, can you show how you have wired the brake relays? The out9 pin is on the GND side (all switching MOSFETs are on the GND side, after the load), so you need to supply 24V to the positive side of the brake relay (you said you were going to get a 24V PSU for the brake) and connect from the negative side of the relay to out9 pin (not the VOUTLC2 pin on the OUT 9 connector, this is just the input voltage, which I think is 48V?).

I don't think you need the CAN address of the pin in the M569.7 command, so try changing that to:

M569.7 P0.2 C"out9" S20

Some changes for your config.g to avoid errors:
Comment out this:

Remove this from the end of config.g, you don't want to load config-override.g then immediately save it again:

Amagatth

@droftarts i change my 24 V now the board is on 24V ( 48V before) so i can direct command brake with out 9 in 24V

and i delet the line no pb

dc42

@Amagatth Brake PWM is implemented on the EXP1HCL and on the M23CL. I have used PWM to run a 24V brake with 48V supply. It appears to work properly although the brake makes a slight hum at the PWM frequency.

Which board are you using to drive the motor and brake?

Amagatth

@dc42 Its ok i put my card in 24 V i use a duet 3 6hc + 3hc with brake on duet 6hc and motor on 6hc

droftarts

@Amagatth And the brake is working now?

Edit:
I've updated the M569.7 entry to say:

Vnn (optional, supported in RRF 3.5 and later on EXP1HCL and M23CL that accept 48V VIN) Brake voltage.

And added a second example:

M569.7 P0.2 C"out9" S20 ; driver 2 on mainboard uses port out9 to control the brake, with 20ms delay

Ian

Amagatth

@droftarts no if i make a m18 moto are disable but dont active 24 v for brake

droftarts

@Amagatth okay, @dc42 has it on his list to fix. See https://github.com/Duet3D/RepRapFirmware/issues/1023

Ian

dc42 created this issue in Duet3D/RepRapFirmware

closed M17 doesn't re-engage motor brake #1023

Amagatth

@droftarts if i understand this post he say effect is on duet 3 expansion board ... i have my motor on the duet 3 6hc

droftarts

@Amagatth he added code to enable PWM on 1HCL and M23CL. From what I understand, the code has broken turning off motor and enabling brake on other boards, like your 6HC, and the 6XD. But I see from the other thread there is a temporary fix from @timschneider that works for you.

Ian

Amagatth

@droftarts i apply the new .bin file and it work perfectly !

dc42

I have now implemented a fix (the same as Tim's fix) for this issue in the 3.5-dev and 3.6-dev source code, so it will be included in the next builds. I can provide temporary 3.5.2+1 builds if anyone needs them.
