14.2 Precautions for Using PLC Functions
1. Default setting of PLC communication protocol is 8,N,2 ,19200, station number 2.
2. Host controller can read/write data from/to both the AC motor drive and the internal PLC
program by setting the drive and internal PLC program to two different station numbers. For
example, if user wants to set AC motor drive as station 1 and PLC as station 2, please write
following setting to the host controller:
When setting 01(Station) 03(Read) 0400(Address) 0001(1 data), the host controller can read the
Pr.04-00 from the AC motor drive.
When setting 02(Station) 03(Read) 0400(Address) 0001(1 data), host controller will read X0
data from the internal PLC program.
3. The internal PLC program will stop operation when upload/download programs.
4. When using WPR command to write parameters, parameters can be changed for a maximum of
10
9
times. It is crucial not to exceed this limit to prevent occurrence of serious error.
5. When Pr.00-04 is set to 28, D1043 value of PLC register will be displayed on the digital keypad:
0 ~ 999 display:
1000 ~ 9999 display: It will only display the first 3 digits. The
LED at the bottom-right corner will light to indicate 10 times of
the display value. For example, the actual value for the
following figure is 100X10=1000.
10000~65535 display: It will only display the first 3 digits. The
LED at the bottom-right corner and the single decimal point
between the middle and the right-most numbers will light to
indicate 100 times of the display value. For example, the
actual value for the following figure is 100X100=10000.
6. When PLC Stop mode,

使用。
7. When PLC is in PLC Run or PLC Stop mode, Pr.00-02 (settings 9 and 10) are disabled.
8. When Pr.00-02 is set to 6, PLC function settings will return to factory settings.
9. When the Input Terminal X of PLC is programmed, the corresponding MI will be disabled (no
function).
10.

12. When PLC function is programmed with FREQ command, AC motor drive frequency is now
under PLC function control. The setting of Pr.00-20 and Hand ON/OFF are disabled and has no
control over AC motor drive frequency.
