    Re: Proximity Sensor Wiring Issue? Help needed.

    Hi Ronald

    any silicon small signal diode like the 1N4148 would do

    a 1A rectifier diode like the 1N4001 to 1N4007 will be mechanically more robust

  3. Re: How I fixed my Chinese TB6560 controller (updated)

    with a TB6560AHQ

    I expect you will set the current to 75% ( 3.5 x 0.75 = 2.625A ) a bit less than the 2.8A but should be OK with 94 % of the motor torque

    to get near to 1.4A for ...
  4. Re: How I fixed my Chinese TB6560 controller (updated)

    Did you get a manual with the new board so you know if you can set the current to 2.8A ?
    and do you have the manual for the old board to see what the motor curren was set to ?

    Re: Proximity Sensor Wiring Issue? Help needed.

    Hi Ronald

    use the 24V supply as the G540's 48V supply is more than the sensors 6 - 36V supply range

    Re: Using relay w/ G540 - 5v or 36v coil

    why not a 48V relay ?

    then you can use the G540's 48V supply

    what are you controlling with the relay ?
