Title: Stepper motor opto
Post by: babinda01 on September 18, 2006, 06:41:14 PM

Hi,
I've just bought a T100MD888, and I need to drive a stepper motor with it.  The docs suggest a H11L2 as the opto, but I can only source H11L1's in the time frame that I have.  Will this divice work ok???  I will be running the PLC from a 12VDC supply.

Regards
Andrew

Yes, you should be able to use H11L1, L2 or L3. L1 is more sensitive since it requires less current to turn on the emitter in the optocoupler so use a larger resistor to reduce the sensitivies to noise.
