The output status of DOx(2) will
ON
, if the output frequency is
EQUAL to the preset frequency defined in Pr.49
.
Definition of EQUAL means: Difference is within the allowable tolerance defined in Pr.50.
* Relative functions are
SPO, SPZ, and SPA
.
9.4 ALARM output function (complement of Sec.9.5)
The output status of DOx(4) is normally
OFF
when the inverter detects
no error
.
If
error occurs
, the output DOx(4) will
ON
immediately.
9.5 NOT ALARM output function (complement of Sec.9.4)
DOx(5) = /DOx(4)
9.6 BRAKING function (Refer to Section 5.4, Pr.05~Pr.08)
The output DOx(6) will
ON
, when the inverter is under
DC injection braking
mode.
9.7 RUNNING function (Refer to Section 5.4, Pr.05~Pr.08)
The output DOx(7) is
OFF
when the inverter is under
standby
mode (not running).
If the inverter starts running or under DC injection braking mode, the output DOx(7) will
ON
.
9.8 SPO Speed Over function (Refer to Section 9.2)
The output status of DOx(8) will
ON
, if the absolute value of output frequency is
OVER the preset frequency defined
in Pr.49
. (i.e. Pr.57>Pr.49)
9.9 SPNO Speed Not Over function (complement of Sec.9.8)
DOx(9) = /DOx(8)
9.10 SPA Speed Arrive function (Refer to Section 9.2)
The output status of DOx will
ON
, if the output frequency is
EQUAL to the Set frequency.
Definition of EQUAL means: Difference between output Hz and desired frequency is within the allowable
tolerance defined in Pr.50.
Note: the SPA signal is always OFF if inverter is not running or is under DC injection braking.
9.11 SPNA Speed Not Arrive function (complement of Sec.9.10)
DOx(11) = /DOx(10)
9.12 DIRECTION output function
The output status of DOx(12) will
ON
, if the output frequency >=0.
The output status of DOx will be
OFF
, if the output frequency <0 .
Refer to Sec.9.90 & 9.91
9.13 IRMS-LEVEL0
DOx(13) output will ON, if Irms>Pr.48.
Irms is root mean square current value of inverter output.
9.14 TMOA Timer Output A-type function (Refer to Section 8.7)
Refer to the Functional block diagram of Timer/Counter module in Sec.8.7 and the related descriptions.
9.15 SPZ Speed Zero function (Refer to Section 9.2)
The output status of DOx will
ON
, if the output frequency is
EQUAL to Zero.
(Pr.57<Pr.50)
9.16 SPNZ Speed Not Zero function (complement of Sec.9.15)
DOx(16) = /DOx(15)
9.17 STALLING function
While inverter running, if the output current exceeds hardware limit (150%), the output frequency will decrease
automatically to reduce the output current. Inverter running under such condition is called Stalling, and output status
DOx(17) will become ON to indicate this situation.
