Inputs & Outputs
Example: Set n002 to “SEQ=TRM REF=TRM”.
Open: Frequency reference from control circuit terminals FV & FI,
and run command from control circuit terminals S1 and S2.
Closed: Frequency reference and run command from serial communi-
cation.
·Timer Function (setting: “Timer Start Cmd”)
The timer function is used in conjunction with the multi-function con-
tact output (parameter n041 or n042 set to “Timer Output”).
When the timer function input is “closed” for longer than the ON-delay
timer (n080), the timer function output closes.
When the timer input is “open” for longer than the OFF-delay timer
(n081), the timer function output opens.
·Analog Reference Sample/Hold Selection (setting:”Ref Sample Hold”)
This feature allows a single analog signal to be used among multiple invert-
ers to “sample and hold” separate speeds. Each inverter can be commanded
to acknowledge the reference at different times. If the analog reference
sample/hold input terminal is “closed” for 100ms or longer, the analog fre-
quency reference is sampled; when it opens, the analog frequency reference
is held.
Note:t1, t3 - Reference is sampled once with an input closure of 100ms or longer.
t2 - Reference is not sampled with an input closure of less than 100ms.
