TMCM-090

[Zion]

Hi,

I am a reseacher from Imperial College London. I am now using TMCM-090 to control a Piezoleg motor in step/direction mode. I find the motor drive becomes quite hot (around 50 degree for particular components in the TMCM-090) when I drive the motor. And a TMCM-090 has been burn before. Therefore, I would like to clarify the following things:

1) Pin 11, Step_ENN should be connected to ground if I want to activate the motor.

2) Even though the maximum operational frequency for the piezomotor is 3kHz, the operational frequency for TMCM-090 can be up to 384kHz

3) I find maximum speed of the motor occurs when the operational frequency for TMCM-090 is about 90kHz rather than 384kHz. A frequency higher than this would result in resonance. Is it normal?

4) I just find that BB-035 may be suitable for TMCM-090, avoiding terrible soldering. May I know if you have educational prices for academic college?

5) In BB-035, D- is direction input (inverted), which does it mean?

1) Yes, that's right. It enables the outputs of the module when connected to GND.

2) Yes, also this is right, but it refers to the microstep rate. The motor manufacturer refers to the fullstep rate, which is microstep rate / microstep resoulution. Please be careful not to exceed the rated 3kHz fullstep rate.

3) I think that this depends on the motor you are using. Please try also to select a different waveform.

4) As a developer here I can not say much about prices. But until now I did not hear about special educational prices.

5) The BB-035 also offers differential inputs for step and direction input. When using single-ended signals, only D+ and S+ are to be used. When using differential signals (which is to be recommended when using long cables in noisy environments) the non-inverted signal is to be connected to D+ and the inverted signal must be connected to D- (and the same also with S+ and S-).

Hi,

I just want to make the TMCM-090 connected to BB-035 working with the simplest methods to drive a piezoleg linear motor exactly same the model attached in your website related to TMCM-090.

I have followed the menus of TMCM-090, BB-035 and the menu for BB-035 with the use of TMCM-090 step by step while it is still not working... I would like to clarify about the plug setting.

1) Would you mind to reply me with a picture regarding all required setting of jumpers on the BB-035? The waveform I want is Rhomb F maximum force (32)

2) The following is my connection and I am not sure what’s wrong with it.

My connection is as follows:

2.1) For the 2 INAB, RSA2, RSA1 and STOP,
How should I set the jumpers?
Please mention this part in detail.

2.2) The 14 pins in X1 header.
It is not connected to anything as I use the simplest step/ direction control

2.3) D-: Ground
D+: a signal which is either 0 or 5V to control direction of the motor
S-: Ground
S+: a step signal with a frequency from 0 to 384 kHz
(I think single ended step/direction is ok for my application)
I am not sure what the differential step/ direction is. Would you mind to explain more????

2.4) Power supply on the top left hand corner of the board:
V+: 48V
0V: Ground

2.5) Motor:
B B A A: phase of motor 1 2 3 4
Or 4 3 2 1
Both should be ok, right????
The ground of motor has been connected to the ground of the board.

All grounds are connected together as a common ground

Thank you very much.

Hi,
1)
please take a look at the manual

http://www.trinamic.com/tmc/media/Downl ... _piezo.pdf

and

http://www.trinamic.com/tmc/media/Downl ... manual.pdf

and

http://www.trinamic.com/tmc/media/Downl ... manual.pdf

to find out. This Board is designed for the TMCM035 but you can use it allso for the TMCM 090. There are funktions on it witch you don´t need for the piezodriver.

(all jumper is set)
2) ?

2.1) not connected
It´s normaly a board for the TMCM 035 and there you need it.

2.2) not connected
It´s normaly a board for the TMCM 035 and there you need it.

2.4)

2.5)
BB-035_manual.pdf page 10
it turns the direction

Ground is ground. There is no analog GND.
