E . Data 18 : Timer Input Function
H 2 - 0 1 : Multi-function Output Terminals (9 & 10)
H 2 - 0 2 : Multi-function Output Terminals (25 & 27)
H 2 - 0 3 : Multi-function Output Terminals (26 & 27)
b 4 - 0 1 : On-delay Timer
b 4 - 0 2 : Off-delay Timer
When the timer function input is "closed" for longer than On-delay Timer ( b 4 - 0 1 ), the
timer function output closes.
When the timer input is "open" for longer than Off-delay Timer ( b 4 - 0 2 ), the timer function
output opens.

As can be seen, the timer function must be programmed as both a multi-function input a n d
an output to be effective.
F . Data 1E : Sample/Hold Command
This function applies only to an analog voltage or current input used as a frequency
reference at terminals 13 or 14.
If the Sample/Hold command is present (contact is closed) for more than 0.1 sec., the
frequency reference will follow (sample) the analog signal, e.g. if 5V corresponds to 50%
frequency, a 5V analog signal will produce 50% frequency reference if the Sample/Hold
command is present.
If the Sample/Hold command is removed (contact is opened) while the Drive is still in Run
condition, the frequency reference is held at the level it was at the time the Sample/Hold
command was removed, e.g. the frequency reference would remain at 50%, even though
the analog signal increased to 8V.
