11.22.3 PROFIBUS-DP Communication Card (OPC-PDP2)
By installing the PROFIBUS-DP communication card in FRENIC-MEGA and connecting to the
PROFIBUS-DP master device, run commands, frequency commands, and the operating status can be
monitored, and all FRENIC-MEGA function codes can be changed or referenced.
The features of this communication card are shown below.
- PROFIBUS version: DP-V0 compatible
- Baud rate: 9,600 bps to 12 Mbps
- Compatible profile: PROFIDrive V2
- Reading/writing to all FRENIC-MEGA function codes possible
Applicable port
This communication card can only be installed in the A port of the three FRENIC-MEGA option
connection ports (A, B, and C ports).
[Note] Other communication cards (DeviceNet communication card, SX-bus communication card, etc.)
cannot be installed with this communication card installed. If multiple communication cards are installed,
an er4 trip will occur at FRENIC-MEGA, and it will not be possible to cancel the trip condition until
there is only one communication card installed.
PROFIBUS-DP specifications
Table 11.22-6
9.6, 19.2, 45.45, 93.75, 187.5, 500 kbit/s
1.5, 3, 6, 12 Mbit/s (automatic detection)
1472 bytes (SPC3 built-in memory)
Setting with rotary switch (0 to 99) or setting with
inverter function code o31 (0 to 125)
o31 is valid when the
rotary switch is set to 0.
