Establishing a Single, or one Break Line Limit
Diode 26 sets the speed at which horsepower contouring will begin (P1).
D26 is calculated as:
V
Z
= 8*N
s
/ N
max
– 1.5
Where:
V
Z
is the Zener Diode Voltage Rating
N
s
is the speed at which contouring begins
N
max
Is the Maximum System Speed.
The first line segment, P1-P2 or P1-P3, has its slope established by R25. If a single-line segment
approximation is suitable, the resistor must have the line segment intersect at P3 and R30 is a 0
Ω
jumper.
The value of R25 is determined as follows:
R25 =
20,000 * (8-V
z
)
12-(8*I

/ I

)
Where:
V
z
is the Zener Diode Voltage Rating
I
clamp
is the Maximum current at the breakpoint
I
peak
is the Drives Peak Current Rating (2* continuous)
Establishing a Two-Line or Break Limit
If a two-line segment is required, R30 is set to 2K
Ω
, D26 is calculated as above, and R25 is calculated for
the first line segment (P1-P2) with the following equation:
R25 =
20,000 * ((8*N

Where the new variables:
N

= Desired Speed for second break
N
r
= Motor’s Rated Speed
The second line segment (P2-P3) is established using D20A and R31.
POTENTIOMETER ADJUSTMENTS
This section describes the purpose and effects of adjusting each of the drive’s 4 adjustment
potentiometers. Two potentiometers (DC Gain and AC Gain) are located on the comp card and face the
user. The other two potentiometers (Balance and Current limit) are located at the top of the drive unit.
DC Gain – Scale
This potentiometer adjusts the velocity scaling of the drive. The analog input to the drive causes a
commanded velocity to the motor. This potentiometer adjusts the amount of input voltage signal required
to command a given motor velocity. This potentiometer is typically adjusted for 10-volts = rated speed for
systems requiring only velocity control. In systems where the drive is used inside a position loop, it is
common to adjust this pot so that 8-volts = rated motor speed to allow servo headroom.
