Level + time
By this method, the hold detection section is specified as a timer. Hold is detected during the
predetermined time (hold section time) from the point in time when the torque crosses the hold start
level.
The hold value is maintained until the hold reset signal is turned on.
The hold is released by turning on the T/H signal as a reset signal.
There are tracking sections, detection sections, and hold deciding sections.
(Example) Level + Time specified section peak hold
t1: A delay time between the instant

t2: A delay time between the instant
when the detection time is ended
and the instant when the value to be
held is determined
Approximately 1.0ms (MAX.)
t3: A minimum reset signal width
required for releasing the hold
