Mitsubishi Electric FR-A8NP Instruction Manual page 54


Valid only for the FR-A800 series when Pr.1110 PROFIBUS format selection = "1" (extended format). (Refer to

PZD enable and command count request can be executed.

If it takes time to perform slave side processing, slave side busy status is announced since reply to the master will be delayed. During
busy status, other response data are unfixed values. When the slave side is busy, request from the master is invalid. Therefore, the same
request must be sent again. The response data of the FR-A8NP during Busy status is as follows.
During busy status and
ID
inverter reset
PKW 0
ZSW Bit 15 (BUSY) ="1"
PZD
Other error Bit="0"

When a value other than 9999 is set in Pr.430 Pulse monitor selection under position control (Pr.800="3, 4") for the FR-A800 series,
pulse monitor is selected. (Refer to the Instruction Manual (Detailed) of the inverter for pulse monitor.)

Signal names are initial values. Using Pr.180 to Pr.186, you can change output signal functions. Refer to the Instruction Manual
(Detailed) of the inverter for details of Pr.180 to Pr.186.

For the FR-F800 series, no function is assigned in the initial setting.

These signals are set in the initial setting. Using Pr.190, output signal assigned to the device number can be changed.
For the details of Pr.190, refer to the Instruction Manual (Detailed) of the inverter.
NOTE
• Only when the contents of the command request (request for changing the inverter setting: PKW, HSW, STW/ECW)
from the master changed, the inverter processes the request. If the contents of the command request are identical
with those of the last request, the inverter does not process the request. (The received request is cleared.)
For instance, while the master keeps sending the "network operation mode enable" command, changing the mode to
the PU operation mode with switchover function does not allow the "network operation mode enable" command to be
executed due to the same contents as that sent last time. Therefore, the operation mode remains the PU operation
mode without changing to the Network operation mode. In this case, send another command as "PU operation mode
enable" from the master once, then send the "network operation mode enable" command again.
During busy status and
other than inverter rest
All 0 when AK="0"
Reply data when AB"0"
ZSW Bit 15 (BUSY) ="1"
