3.2 Node Address Switches
The node address switches (SW1 and SW2) on the interface card are rotary ones that are used to specify the PROFIBUS DP communications
network node address (station address) of the card. The setting range is from 0 to 99 in decimal. The SW1 specifies a 10s digit of the node address
and the SW2, a 1s digit.
The node address can also be specified with the inverter's function code o31. The setting range is from 0 to 125 in decimal. Note that validating the
node address specified with the function code o31 requires setting the node address switches to "00."
Example 1: Setting the node address 27 using the node address switches
SW1 SW2
1. When the inverter is powered OFF:
Set SW1 to "2."
Set SW2 to "7."
2. Turn the inverter power ON.
Figure 4 Node Address Setting Example 1
The setting procedure is completed.
Example 2: Setting the node address 125 using the function code o31
SW1 SW2
1. When the inverter is powered OFF:
Set both the SW1 and SW2 to "0."
2. Turn the inverter power ON and set the function code o31 data to "125."
3. Turn the inverter power OFF and ON.
Figure 5 Node Address Setting Example 2
The setting procedure is completed.
1. The node address switches should be accessed with all the inverter power (including the auxiliary power) being OFF. Setting
these switches with the inverter power being ON requires turning the power OFF and ON to validate the new setting.
2. To validate the node address setting using the function code o31, restart the inverter.
3. Setting the function code o31 data to "126" or greater will cause a data setting error. The ERR LED on the card blinks in red and
the inverter issues the alarm code er5.
3.3 Terminating Resistor Switch
The PROFIBUS DP communications network requires insertion of line terminating resistors at its end. When the card is mounted in the inverter at
the end of the network, turn this switch ON to insert the terminating resistor. No external terminating resistor is required.
OFF: No insertion of terminating resistor ON: Insertion of terminating resistor
Figure 6 Terminating Resistor Switch
3.4 Terminal Board
This card provides two terminal blocks, one for the PROFIBUS communications and another for grounding (earthing).
For wiring of the terminal blocks, refer to Chapter 5 "WIRING."
3.5 Setting the Transmission Speed (Baud rate)
No transmission speed setting is required on the interface card (slave). Setting the transmission speed in the PROFIBUS DP network master node
automatically configures the transmission speed of this card.

Figure 14 illustrates a status transition diagram of the PROFIdrive profile.
Immediately after the inverter power is turned ON, the status first moves to S1 "Not ready to turn a run command ON." Bit manipulation in CTW
shifts the status to S2 "Ready to turn a run command ON," S3 "Ready to run" and finally S4 "Running" in sequence. In S4 state, the inverter enters
the running state. Turning a run command OFF in S4 state shifts the status to S5 "Turn a run command OFF." After the motor stops, the status
moves to S2 or S1 state.
In Figure 14, to simplify the description, values of Bit 4 to Bit 6 and Bit 10 in CTW are always "1." If any one of these bit values is not "1," the
inverter will not enter the running state even if the status transition properly proceeds.

(3) MRV (frequency command) and MAV (output frequency)
MRV and MAV are word areas for setting a frequency command and monitoring an output frequency, respectively.
MRV: Frequency command word area that sends a frequency command from the PROFIBUS DP master node to an inverter (slave node).
MAV : Output frequency monitoring word area that returns the current inverter's output frequency to the PROFIBUS DP master node as a response
from the inverter (slave node).
In each word, the frequency is expressed relative to the maximum frequency (defined by F01 in Hz) being assumed as 4000he x. The conversion
expression is shown below.
MAV orMRV
(Hz)Frequency
(Hz)F03 code Function
4000hex
(Hz) F03 code Function(Hz)Frequency or
4000hex
MAV orMRV
A negative value is expressed by 2’s complement of 4000hex. When the inverter is running in the reverse direction, the value of MAV
(output frequency) is a negative value. Setting a negative value to MRV (frequency command) causes even a run forward command to run
the motor in the reverse direction.
(4) PCD1 to PCD4
PCD1 to PCD4 are word areas exclusively supported by PPO type 2 and type 4. They enable cyclic write request and read (monitor) response
to/from up to four inverter’s function codes previously specified for each of PCD1 to PCD4.
Values written and read to/from the specified function codes are in the same data format as defined in individual inverter's function codes.
For the formats of inverter's function codes, refer to the RS-485 Communication User's Manu al (MEH448), Chapter 5, Section 5.2 "Data
Formats."
To assign inverter ’s function codes to PCD1 to PCD4 words, use function codes o40 to o43 and o48 to o51 as listed in Table 13. Table 14 on the
next page shows how to use these function codes.

• After setting up function codes o40 to o43 and o48 to o51, turn the inverter power OFF and ON to validate the new setting.
• If a same function code is assigned to the PCD areas using function codes o40 to o43, the function code assigned by the o code with the
youngest number takes effect and other assignments will be ignored.
• Inverter’s communication-related function codes S01 and S05 act as a reading specific code in this interface card. Therefore, assigning
these codes to a PCD word area as a write request will be ignored.
Bits in the function code S06 are writable except bit 0 and bit 1. Data written in bit 0 and bit 1 will be ignored.
For details about inverter’s communication-related function codes S01, S05 and S 06, refer to the RS-485 Communication User's Manual

Chapter 10 INVERTER REACTION TO PROFIBUS COMMUNICATIONS ERRORS
The PROFIBUS DP master node can be equipped with a watchdog timer (WDT) that detects communications timeout for monitoring the
communications status. If this card receives no response within the WDT timeout length, it interprets the timeout state as an occurrence of a
communications error.
Inverter's function codes o27 and o28 specify the inverter reaction to be taken after such an error occurrence. (See Table 18.)
For the setup of WDT in the PROFIBUS DP master equipment, see the user’s manual of your master equipment.
For the error indication on the card at the time of a communications error, see Chapter 3, Section 3.1 "Status Indicator LEDs."
If a communications error occurs immediately after the inverter is powered on, no er5 trip will be issued. The er5 trip is issued when a
communications error is detected after once the card received data normally.

After the time specified by o28, coast to a
stop and trip with er5.
If the inverter receives any data within the
time specified by o28, ignore the
communications error. After the timeout,
coast to a stop and trip with er5.
Keep the current operation, ignoring the
communications error.
(No er5 trip)
Immediately decelerate to a stop. Issue
er5 after stopping.
After the time specified by o28,
decelerate to a stop. Issue er5 after
stopping.
If the inverter receives any data within the

Chapter 11 ALARM CODE LIST
In PROFIBUS DP communication, alarms that occur in the inverter can be monitored with malfunction codes in the PROFIdrive specific parameter
PNU974 or with alarm codes in the inverter's function codes M17 through M19.
(1) PROFldrive specific parameter PNU947
(2) Inverter's function codes M16, M17, M18 and M19 (latest, last, 2nd last, and 3rd last alarm codes).
Table 19 lists their malfunction codes and alarm codes.
The data format used for PNU947 is different from that for the inverter's function codes M16 to M19.
For details about PNU947, refer to Chapter 9, Section 9.3 (4) "PROFIdrive Specific Parameters."
