EQ7 Series Instruction Manual - TECO-Westinghouse Motor Company

• Torque Limiter (Target quadrants) (H75)
H75 selects the configuration of target quadrants (Drive/brake, Forward/reverse rotation) in which the specified
torque limiter(s) is activated, from "Drive/brake torque limit," "Same torque limit for all four quadrants," and
"Upper/lower torque limits" shown in the table below.
Data for H75
Target quadrants
0: Drive/brake Torque limiter A applies to driving (both of forward and reverse), and torque limiter B to
braking (both of forward and reverse).
1: Same for all
four
quadrants
Torque limiter A applies to all four quadrants; that is, the same torque limit applies to both
driving and braking in the forward and reverse rotations.
2: Upper/lower
limits
Torque limiter A applies to the upper limit, and torque limiter B to the lower limit.
Depending upon the polarity of torque limiters A and B, the following patterns are available.
Torque limiter A Torque limiter B
Pattern 1 Positive Positive
Pattern 2 Positive Negative
Pattern 3 Negative Negative
