PMDC SERVO MOTOR WITH quadrature encoder DRIVE ?

[phoenix_1]

Now little about PMDC breaking.
1.H-bridge drive of PMDC:

2.Slow DINAMIC break by short with same polarity of power supply.
Bad idea for fast servo PID control.

3.Fast RECUPERATIVE break good for PID control but must use high frequency of PWM.
The best is ~ 15-20KHZ.
Work for me good , but you need good DIODE in H-bridge for EMS breaking.

Thank's and regard's Robert
