10-3-10. Pulse Hold
Values are held when external pulses are input. There are three pulse inputs.
Only one point is held for each pulse input.
Also, for the set values of High and Low Limits, the target channels are fixed as
HOLD 1: operation ch, HOLD 2: operation ch+1, and HOLD 3: operation ch+2. (When
the operation ch is 31ch, the target channels are fixed as HOLD 1: 31ch, HOLD 2: 0ch,
and HOLD 3: 1ch.)
Inputs of the same signal from the second time onward are ineffective.
t1: Delay time between the instant when the T/H signal is input and the instant when
detection starts.
Ts+0.8msec (max.)
t2: Delay time between the instant when the T/H signal is cancelled and the instant when
the indicated value returns to tracking.
Ts+0.8msec (max.)
t3: Delay time between the instant when the HOLD signal is input and the instant when
the indicated value is held.
Ts+0.8msec (max.)
