"PWM based DC Servo Motor Control"

[Nick]

Hi,

I have a application to drive a DC Servo Motor, the details are 50V
1Amp.,
Control Signals -
1) Ei = -10V to +10V. (For speed and direction control such as
a) -10V for High speed Clock Wise
Direction
b) 0 V Motor Stop
c) +10V for High speed Anti -Clock
Wise Direction
2) Enable - High for Enable Motor Rotation.
Low for Stop Motor Instantly.

We have a Tachogenerator as well as encoder to generate the feedback
loop.

Please suggest a device at present i am using "Allegro 3959" and "3637
for PWM", but i am finding it quite difficult.

Thanks and regards...
