PPO-Type5 4WORD + 10WORD = 14WORD

Figure 3.1 PPO–Type Configurations
PPO–Type settings are determined from configuration data sent from the master.
With the PBUS66-Z, in order to change a pre-set PPO–Type, it is necessary to turn off theinverter power supply, turn the power back on, and set up with new configuration data sentfrom the master.
In the above frame configuration table, PKW is used for reading and writing of the inverter internalparameter data.
The data length for the PKW part is fixed at 4 words. (For more information, please refer to Section
3.7.)
Since PPO–Type 3 and 4 do not have a PKW part, reading and writing of inverter internalparameter data cannot be performed using communication.
The PZD part consists of communication data cyclically exchanged between the master and slave.
PZD1 and 2 carry special meanings. PZD1 is bit data called “control word” or “status word”. PZD2
indicates a set value or actual value.
For example, with the above mentioned PPO–Type 1, PKW = 4 words + PZD = 2 words for a totalof 6 words are exchanged between the master and slave.

Items contained within parentheses are used when the built-in PLC function is enabled.

* Note 1: If c-00 is “0” (multifunction input at terminal block), or the built-in PLC function is being used, thiscommand works the same as a regular stop.
* Note 2: If this command is used, the motor will be instructed to stop suddenly so be extra careful to avoid
damage to connected equipment or the inverter.
Also, when c-00 is “0”, or the built-in PLC function is being used, this command works the same as aregular stop.
* Note 3: If this command is used, the motor will be instructed to stop suddenly so be extra careful to avoid
damage to connected equipment or the inverter.
Also, when c-00 is “0”, or the built-in PLC function is being used, this command works the same as a“set value prohibited” command.
* Note 4: When c-00 is “0”, or the built-in PLC function is being used, this command is ignored.
* Note 5: If 2 or more of each of the OFF1, OFF2 and OFF3 commands are input simultaneously, the order ofpriority is OFF2-OFF3-OFF1 starting at the highest one.

PROFIDRIVE (Control Word) Operating Procedure

The following is an extract from the PROFIDRIVE Profile. For more information, please refer to the
PROFIDRIVE Profile.
■ Operation Command
Firstly, the [ XXXX X1XX XXXX X110 ] OFF1 Command control word is transmitted from themaster to the slave.
(X is set as either “0” or “1” depending on circumstances.)
The slave enters the “Ready to switch on” state.
Then, by setting Bit 0 to "1” [ XXXX X1XX XXXX X111], the slave enters the “Ready” state. After
that, by setting Bit 3 to “1”, it enters a state of operation.
CAUTION: If Bit 3 = 1 during an OFF1 command [ XXXX X1XX XXXX 1110 ],operation will commence the instant Bit 0 changes to “1” so please
exercise caution.
■ JOG Command
In the above-mentioned operation command state, when the value of Bit 4, 5 and 6 are "0” andBit 8 or Bit 9 is “1”, a Jog command will commence.
With the PBUS66-Z, when both Bit 8 and 9 are “1”, priority is given to Bit 8.
■ Fault State Acknowledgement
When the inverter starts protection operation and enters a fault state (status word Bit 3 = 1), themaster acknowledges the fault by setting the “fault acknowledge” bit (Bit7) from 0 to 1.
If the inverter protection state is canceled after fault acknowledgement, fault state (status word Bit
3 = 1) is cancelled and operation is resumed by the procedure shown in the following clause.
■ Resuming Operation From a Special State
After the inverter is stopped by the OFF2 or OFF3 command, or when protection operation iscanceled and fault bit cleared after fault acknowledgement, the slave enters the“Switch-on-inhibit” special state. In order to cancel this state and resume operation, it isnecessary to enter the OFF1 state [XXXX X1XX XXXX X110] once. Note that while in the“Switch-on- inhibit” state, the inverter will not operate even if an operation command is input.

CAUTION:-

When using the built-in PLC function in Mode 0, the value of i00010 will be cleared to “0” if thecontrol word is in any of the following states:- OFF1, OFF2 or OFF3 state- Ramp-Function Prohibited state- Set Value Prohibited state3.5 Operation Command / Status Flag / Fault Flag / Multifunction Input and Output

3.6 Diagnosis Data
PROFIBUS-DP has been designed with a “Slave_diagnostics” diagnosis data function where the slave
status information is sent from the slave to the master. For the PBUS66-Z, when the slave (VF66B
inverter) enters a protection state, or when the protection state is cancelled after fault acknowledgement(after protection state is cancelled for Mode 1), the external diagnosis data is updated and a diagnosis
read request is submitted to the master.
The contents of the PBUS66-Z external diagnosis data are explained as follows. The diagnosis dataconsists of a communication frame with a unit of bytes. After turning on the inverter power, when theprotection state has never yet occurred, the contents of external diagnosis data (Figure 3.3 byte numberof +6 and up) are undefined. The external diagnosis data contents are cleared once the inverter poweris turned off.

3.7 Explanation of PKE Part (Inverter internal data access)
The PBUS66-Z uses 4 words from the PKW part of each communication frame to read the VF66B inverter
configuration data, trace-back data, monitor information and protection history as well as to rewrite theconfiguration data.
The format of this PKW part is defined in the PROFIDRIVE Profile.

Protection detection by a GAC board. (only for models using GAC PCB)
200V model: When D.C. part voltage exceeds 400V, protection works.
400V model: When D.C. part voltage exceeds 800V, protection works.
If an output current effective value operates for more than 1 minute with 150% of
motor amperage rating values, overload protection will work.
Protection works by failure of a current sensor.
After operation or jog instruction input, even if 10 seconds pass, when operation is
impossible, protection works.
When motor speed exceeds fault speed setting, protection works.
(Induction motor vector mode / ED motor vector mode)
When output frequency exceeds a fault frequency setup, protection works.
(V/f mode)
200V model: If D.C. voltage becomes less than 180V during operation,
protection will work.
400V model: If D.C. voltage becomes less than 180V during operation,
protection will work.
When over-torque protected operation is set as ON and it operates for more than 1
minute by 150% of rated torque, protection works.
(Induction motor vector mode / ED motor vector mode)
When the temperature of IGBT becomes beyond a predetermined value,
protection works.
When the setting data memorized by the built-in memory cannot be acquired correctly,
protection works.
If option substrate use is set as ON and an option substrate causes a defect ofoperation, protection will work.
In sensor-less mode, when the phase detection at the time of starting goes
wrong, protection works. (ED motor vector mode)
When a communication error (timeout) is caused between an option and a master at
the time of the option use which performs network communication, protection works.
When rate control unusual detection is set as ON and the deviation of motor speed
and an instruction value (rate control input) exceeds a preset value (console setup),
protection works. (Induction motor vector mode / ED motor vector mode)
When motor temperature exceeds 150 degrees C at the time of ON at the time oftemperature detection option use in a motor overheating selection setup (F-06),
protection works.
In a model of 7.5kW or less, when charge resistance is overheated, protection
works.
When an instant current limit (FCL) continues for 10 seconds (near 0Hz 2 seconds)
continuously, protection works.
When it starts in the state where a setup of motor rating and a motor constant has
abnormalities, protection works.
