3.3 Operation
•
The program error may flash when used for the first time because the EEPROM (user program memory) is
not initialized. In the personal computer or FX-20P (off-line mode), transfer and write a program in that
status. In the FX-10P or FX-20P (online mode), execute all NOP write to erase the contents.
•
After writing a program, make sure to verify.
•
Set the memory protect switch to OFF before writing a program. During normal operation, it is recommended
to set it to ON to prevent erroneous write.
•
When installed in the FX
2N
or FX
2NC
Series PLC version 3.00 or later, the EXTR (FNC 180) instruction and
the 16k-step EEPROM and clock function can be used.
If installed in the FX
2N
or FX
2NC
Series PLC earlier than version 3.00, only the 16k-step EEPROM and clock
function can be used.
4. Inverter Communication Function
• When handling the PLC or inverter, follow the notices indicated in each manual which is
included with the main unit in order to avoid electric shock, fire, a damage or an accident.
• Make sure to perform class D grounding of the ground terminal of communication equipment for
the PLC together with that of the PLC main unit. Ground the shield of a shielded cable at one
point on the PLC. Do not, however, ground at the same point as high voltage line. If grounding is
imperfect, effects of noise or surge induction takes place, and it may cause a communication
error or erroneous operation.
• The signal cables must not be laid near or bundled with the main circuit lines, high voltage power
cables or load carrying wires. Otherwise effects of noise or surge induction are likely to take
place, and it may cause a communication error or erroneous operation.
Keep a safe distance of more than 100mm (3.94") from these wires.
4.1 Outline of Functions and System Configuration
When using K10 to K13 of the EXTR (FNC 180) instruction, operation monitoring, control value write or
parameter monitoring and change in the A500/E500/S500 (with RS-485 communication function) Series
MITSUBISHI TRANSISTORIZED INVERTER can be performed.
The details of programming and setting can be found in the Programming Manual
