Brother TC-211

any chance of nice electronics for dummies drawing and maybe some part numbers for radio shack, and where to wire it in. The brake is only 24 volts. Or I think it is the z axis brake. It sits on top of the ball screw under the z motor coupler, and has 2 wires coming out of it (24 volt)

Almost any small 24V SPST NO or SPDT relay will work,
the brake will need a flyback diode or you will weld
the relay contacts.
(this diode may be already present across the brake coil)

what type of toolchanger is fitted ?
how does it work ?

before you go wiring something you may not be sure of if it is a brake ( although the chances are it is)
take a picture and lets confirm this

The took changer is a ten tool rotary style that rotates around the z axis and spindle. The z axis had to go above the home position. The changer rotates then comes down on the tool. (Bt-30) style tool holders. this is a video of the same machine. ( not mine but same Model)

Ok picture time and some ramblings



in this page of the book the z axis brake is defined as RY16 BMR- Z-axis brake



On this page pin 139 and 140 are internal use 24v and listed as BMR
could this be the pin out for the brake ??????



This is the top of the z axis where the servo motor is mounted



sorry blurry but you can see the coupling on top and the wires leading into the brake (I hope)

Amy input from the linux master's here does my idea on the wires sounds right and or does that look like the z axis brake

yes thats the brake , so make it that a relay puts 24v across the coil when the z axis is disabled , easiest way is to have the relay on the amplifier enable for z axis
and wire so the z amplifier is enabled and the brake is disabled , using a 2 pole changeover relay , so they cant both be on at the same time , so on an energised relay the brake is powered ( across the normaly closed contacts ) on i pole , and the amplifier enable on the other pole but using the normaly open , then you only need to worry over 1 enable line and the brake will look after it's self , if you get my meaning

Ok read through your advise and a little lost

also had my electronics specialist/consultant read it



and both of us are lost. A simple diagram would be great if possible.

(And everyone is wondering why this is taking me so long )

Also checked pin 139 - 140 . They are the wires that control the brake thru the onboard relays. How would I wire them in to prevent the z axis from dropping.

Is there anyway to right the z brake into the hal or ladder something like
if z is active power 24v
if z is not active no power
Using what I have readily avaliable on z servo I don't have 24 volts to wire the brake into
