ABOUT LED INDICATOR ON TMCM140-42-32

[layman2008]

DEAR SIR:
NOW I AM USING A TMCM140-42-232 CONTROL BOARD TO DRIVE A STEPMOTOR.THERE ARE TWO LED INDICATORS ON TMCM140-42-32,WOULD YOU LIKE TO TELL ME WHAT THE TWO LEDS INDICATE?THANKS.

[Goeran Eggers (TRINAMIC)]

Both LEDs (red and green) on the board are controlled by the on-board processor / firmware. The functionality is dependent on the firmware actually used:

- TMCL: green LED: usually blinking slowly - indicating normal operation

- CANopen: behaviour of both LEDs according to CANopen standard (indicating state).

HELLO ,WHAT DOES THE RED LED LIGHT INDICATE(IF THE RED LED IS LIGHTED )?THANKS.IS THERE A POWER LED ON TMCM140-42-32

[Olav Kahlbaum (TRINAMIC)]

There is no power LED on the TMCM-140. The red LED on the TMCM-140 is not used with TMCL. It is only used in the CANopen firmware to indicate CAN bus errors. And in bootloader mode, both the green and the red LEDs are constantly on.
