1.0 INTRODUCTION
The unit is field wired to a back panel terminal strip. Seven terminals are of interest:
• 2 “AC” terminals. Connect 115VAC.
• 2 “BRAKE” terminals. Connect to brake.
• “5V” terminal. Connected to speed pickup +5VDC
• “5VRTN” terminal. Connected to speed pickup return.
• “FREQ” terminal. Connected to speed pickup output.
Note: There are three"EARTH" terminals.Thesecan be usedas protective
grounds if shield wire is used. The chassis of the unit is not
connected to any of these terminals.
Both AC inputs and the brake output is fused internally. See back panel for size. The 5V output is
not fused.
The control algorithm is a simple PI ( Proportional, Integral ) routine where the current to the brake
is governed by:
Current to brake = Coef P * x(n) + Coef I Σx(n)
Coef P = user selected P value²
Coef I = user selected I value² divided by 10
x(n) = (rpm - set speed) / set speed
The equation is calculated every 10 milliseconds and the value is sent to a 16-bit D–A Converter.
