I am trying to set up a TMCM-090 with a BB-035 in step and direction mode and much like the earlier post and not having any success.
Here are my settings:
X1 Pin1 jumped to GND no other connections on this header
I am trying to set it for Rhomb F max force so my jumpers are set in the following manner:
SPE - jumper removed
SDE- jumper present
S16- jumper present
UMD- jumper present
ANN- jumper removed
64U-jumper removed (why is this jumper not shown in manual? I believe it is pin 27 on the TMCM-090 that needs to be high for step and direction?)
All other jumpers removed
I have a red blinking LED on the upper left corner of the TMCM-090. The frequency of the LED changes. It was blinking on 10 seconds, off 10 and so forth. Now it is blinking at about 2 hz with a 50% duty cycle.
What is the significance of this LED and the blink rate?
I am hooked up to a power supply that is giving 48 volts and the BB and TMCM are drawing .05 Amps. Sometime it goes up to .07 amps.
I have single ended step and direction wired to the S+ and D+ lines and S- and D- grounded. I have verified the controller is putting out the step and direction. I have tried both high going pulses and low going with no effect. My pulse train has a 50% duty cycle so a 1khz. pulse train has a pulse width of 50 micro seconds. I believe this is within your spec even at the highest pulse rate.
Does the drive prefer high going or low going pulse trains for step?
I have a Piezo Motor Legs motor hooked up to the drive per the manuals instruction.
When I give it a pulse train, I don't see the current going to the unit increase nor do I hear any noise like the motor is trying to move. What current should I see if the motor were trying to move?
Any suggestions would be appreciated. I am 8 hours into what I thought would be a very easy intergration without any success.
