Error Reset Operation Selection At Inverter Fault; Operation Mode Switching And Communication Startup Mode - Mitsubishi Electric A800-E Instruction Manual

(N) Operation via communication and its settings
CAUTION
 When Pr.502 = "3" and a communication line error occurs, or Pr.502 = "4" and a communication line
error or a communication option fault occurs, the operation continues. When setting "3 or 4" in
Pr.502, provide a safety stop countermeasure other than via communication. For example, input a
signal (RES, MRS, or X92) through an external terminal or press the PU stop on the operation panel.
Error reset operation selection at inverter fault (Pr.349)
• In the External operation mode or the PU operation mode, use this parameter to disable an error reset command sent
through the Ethernet network (CC-Link IE Field Network Basic) or from a communication option.
Pr.349 setting
0 (initial value) Error reset is enabled independently of operation mode
1 Error reset is enabled only in the network operation mode
Operation mode switching and communication startup mode (Pr.79,
Pr.340)
• Check the following before switching the operation mode.
- The inverter is at a stop.
- Both the STF and STR signals are off.
- The Pr.79 Operation mode selection setting is correct. (Check the setting on the operation panel of the inverter.)
• The operation mode at power ON and at restoration from instantaneous power failure can be selected. Set a value other
than "0" in Pr.340 Communication startup mode selection to select the Network operation mode.
• After the inverter starts up in the Network operation mode, parameter write can be commanded via the network.
NOTE
• The changed value in Pr.340 is applied after the next power-ON or inverter reset.
• The Pr.340 setting can be changed on the operation panel in any operation mode.
• When setting a value other than "0" in Pr.340, make sure that the communication settings of the inverter are correct.
