Hi Jeremy,
Question: Do you use 30V for your Motor ? (external)
IF NO:
I´m testing several Motors from copier-machines (12V-24V) with my HB. Some
motors didn´t work properly with PWM.
For example Motor 24V I´m using ist with for 12V Motor (0,100) the
Motor works fine (100=Full speed = 12V)
IF i decrease the speed with PWM (Motor(0,0..100)
the motor didn´t have enough torque !!!!
The main problem is, i found out during my tests, a lot of motors with more
then 12V don´t work properly with PWM,
if you are using lower voltage
Tschau
