(3) Function code data setting
From MICREX-SX, set the function code S08 "Acceleration time" to 30.5s.
(Condition: Function code U11 "SX transmission format selection"= 0, SX bus station address: 10)
%QW10.8 0 8 0 0 Function code S08 selecting (Link No. 08h)
%QW10.9 0 0 0 0
%QW10.10 0 1 3 1 30.5=305 x 0.1s=305=131(h)

(4) Toggle monitoring
Monitor data toggling between MICREX-SX and the inverter. This example set the X12 terminal to
TGL1 and X13 terminal to TGL2.
(*1)
Set E11=72 (TGL1), E12=73 (TGL2), H30=3, H144=0.10 (100 ms) in advance.
This sets transmission toggle (MICREX-SX→VG1): %QW254.0.10.13 bit 12 = TGL1 and bit 13 =
TGL2.
The inverter monitors the toggle pattern sent from MICREX-SX while the operation command is
ON, and generates the toggle error
arf
if the toggle signal cannot be received within the time
specified with H144.
*1 For the details of the toggle, refer to E01 to E13 toggle signal explanation in "4.3 Function Code
Details".
*2 By setting the inverter function code H107, the inverter can continue operation with
l-al
display. Refer to the description of H107 in "4.3 Function Code Details".
*3 The tact period for an application which sends toggle patterns on the MICREX-SX side should
be 1 ms or longer.
%QW254.0.10.13 * 0 0 0 Send 0→1→2→3→0 to *…(toggle pattern)
↓ After sending toggle
%QW254.0.10.13 * 0 0 1 Operation command (FWD)=ON
⇒
arf
does not occur if the sent toggle is correct.
Note: If the network error
er4
(light and heavy alarm 1) occurs while sending the toggle pattern and
keeps the operation, the toggle error
arf
may occur after the communication recovers. To avoid
the toggle error
arf
, stop sending the toggle pattern while the network error
er4
is occurring.
