8.11 DIx_Select = 11, TMIB
Refer to the functional block diagram of Timer/Counter module in Sec.8.7.
When digital input DIx is assigned to
TMIB
function, it serves as
Input of the ON-DELAY
timer. User must assign a digital
output DOx, which select
TMOB
function to serve as the output
of this timer. And the
timer time
will be defined in Pr.71. (Refer
to Sec.8.94)
When the timer input TMIB is OFF, the timer output TMOB will
be OFF too.
Until the input TMIB is ON and
continue ON for a specified
time period of Pr.71
, then the TMOB will become ON.
8.12 DIx_Select = 12~14, reserve
8.15 DIx_Select = 15, CLEAR the content of UP/DOWN COUNTER to Pr.16
8.16 DIx_Select = 16, LOAD the content of UP/DOWN COUNTER to Pr.15
8.17 DIx_Select = 17, HOLD the UP/DOWN COUNTER
Refer to Sec.7.6 Functional Block Diagram of Internal UP/DOWN counter.
Note: These digital function may be selected as the input terminals when Pr.40=6, 7 and 19, using the content of the
UP/DOWN counter as the NORMAL_SPEED_REQUEST.
If DIx(15) is ON, selects CLEAR function, the content of the internal UP/DOWN COUNTER will be set to Pr.16
(Lower Limit).
If DIx(16) is ON, selects LOAD function, the content of the internal UP/DOWN COUNTER will be set to Pr.15 (Upper
Limit).
If DIx(17) is ON, selects HOLD function, the UP/DOWN COUNTER will hold its value.
8.18 DIx_Select = 18, OFF-BB
When any DIx selecting this function, the input terminal must remain in activate state for normal operation. If the input
terminal is left open to OFF state, it will
BLOCK the BASE
signal to all transistors immediately in order to disable the
inverter output.
When the input is ON again, the inverter will execute
Speed Search process
. Refer to Sec.11, the special function for
Speed Search process
.
Also Refer to Sec.8.8 for complement function.
8.19 DIx_Select = 19, UP
If DIx(19) is ON, the UP/COUNTER will increase its value, according to the acceleration rate specified in Pr.01.
8.20 DIx_Select = 20, DOWN
If DIx(20) is ON, the UP/COUNTER will decrease its value, according to the deceleration rate specified in Pr.02.
8.21 DIx_Select = 21, ALARM CLEAR
If user choose this function, then activate the DIx terminal will reset the inverter only when alarm had occurred.
Note: The
RST terminal
is used to
RESET
the whole inverter no matter alarm occurred or not.
8.22 DIx_Select = 22, SET Flip/Flop-1
8.23 DIx_Select = 23, CLEAR Flip/Flop-1
8.24 DIx_Select = 24, SET Flip/Flop-2
8.25 DIx_Select = 25, CLEAR Flip/Flop-2
8.26 DIx_Select = 26, SET both Flip/Flop-1 & Flip/Flop-2
8.27 DIx_Select = 27, CLEAR both Flip/Flop-1 & Flip/Flop-2
Two general purpose Flip/Flops were built in for many applications in order to minimize the necessary external
components. Each Flip/Flop block has two SET inputs, two CLEAR inputs and two complementary outputs for free
selection.
For example, Let
DI1_Select (Pr.41) = 22, select DI1 to be the SET input of FF1
DI2_Select (Pr.42) = 23, select DI2 to be the CLEAR input of FF1
DO1_Select (Pr.45)=32, select DO1 to be the output Q of FF1
then,
the combination of inputs DI1, DI2 and output DO1 will serve as a Latch Relay
.
Momentary ON signal apply to DI1 will cause DO1 enter ON state. On the contrary, ON signal apply to DI2 will cause
DO1 back to OFF state again.
If digital input function select is DIx_select=26, then ON input to DIx will SET both FF1 & FF2.
If digital input function select is DIx_select=27, then ON input to DIx will CLEAR both FF1 & FF2.
Note: Multiple assignment to the same input function is acceptable.
