„ 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).
First quadrant:
Forward driving Second quadrant:
Reverse braking
Third quadrant:
Reverse driving
Fourth quadrant:
Forward braking
Torque limiter A
Torque limiter B
Torque limiter A
Torque limiter B
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.
First quadrant:
Forward driving Second quadrant:
Reverse braking
Third quadrant:
Reverse driving Fourth quadrant:
Forward braking

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
