Important Information
MOVIDRIVE® MDX61B Internal S ynchronous Operation (ISYNC)
1 Important Information
1.1 Documentation
• Read through this manual carefully before you commence installation and startup of
MOVIDRIVE®inverters with internal synchronous operation.
• This manual assumes that the user has access to and is familiar with the
MOVIDRIVE®documentation, in particular the MOVIDRIVE®system manual.
• As a prerequisite to fault-free operation and fulfillment of warranty claims, you must
adhere to the information in the documentation.
1.2 Bus systems
General safety notes for bus systems:
This communication system allows you to adapt the MOVIDRIVE®inverter to your
application. As with all bus systems, there is a danger of modifications to the parameters
that are not visible from outside (in relation to the inverter), which give rise to changes
in the inverter behavior. This may result in unexpected (not uncontrolled) system behav-
ior.
1.3 Operating mode "synchronous operation"
The motion controller in synchronous operation processes setpoint changes at the
master drive. Set the application module in such a way that an unintended motor start
is not possible.
The following measures increase operational safety:
• Deactivating the synchronous operation mode
– when warnings or errors occur within the sync group or when the drives are not
ready for operation
– when the sync group has been stopped
• Selecting the synchronous operation mode with querying the "ready for operation"
message and the "technology options" operating status of all drives.
• If an absolute position reference is required, arrange the individual drives in the
positioning operation mode (no offset control).
INFORMATION
•This manual does not replace the detailed operating instructions.
•Only trained personnel are allowed to perform installation and startup.
Adhere to all applicable accident prevention regulations and the
MOVIDRIVE®operating instructions.

Structure of the safety notes
Important Information
1.4 Structure of the safety notes
1.4.1 Meaning of the signal words
The following table shows the grading and meaning of the signal words for safety notes,
notes on potential risks of damage to property, and other notes.
1.4.2 Structure of the section-related safety notes
Section safety notes do not apply to a specific action, but to several actions pertaining
to one subject. The used symbols indicate either a general or a specific hazard.
This is the formal structure of a section safety note:
1.4.3 Structure of the embedded safety notes
Embedded safety notes are directly integrated in the instructions just before the descrip-
tion of the dangerous action.
This is the formal structure of an embedded safety note:
•SIGNAL WORD Nature and source of hazard.
Possible consequence(s) if disregarded.
– Measure(s) to prevent the danger.
Signal word Meaning Consequences if disregarded
DANGER Imminent danger Severe or fatal injuries
WARNING Possible dangerous situation Severe or fatal injuries
CAUTION Possible dangerous situation Minor injuries
NOTICE Possible damage to property Damage to the drive system or its
environment
INFORMATION Useful information or tip: Simpli-
fies the handling of the drive
system.
SIGNAL WORD
Type and source of danger.
Possible consequence(s) if disregarded.
• Measure(s) to prevent the danger.

System Description
2 System Description
2.1 Application fields
The internal synchronous operation function enables a group of motors to be operated
at a synchronous angle in relation to one another or with an adjustable proportional
relationship (electronic gear). Internal synchronous operation is particularly suited for
the following industries and applications:
•Beverage industry
– Filling stations
•Multiple column hoists
•Synchronous material transport
•Extruder applications, cutting material off the roll to length
– Flying saw
– Rotating knife
•Packaging technology
2.1.1 Advantages of internal synchronous operation
• Option of position-dependent synchronization →smooth synchronizing without over-
shooting
• Option of position-dependent offset
• Signed input of the master gear factor
• Option of synchronization with a virtual encoder
• Option of synchronized SBus connection between master and slave
• Software solution →no option card required
2.2 Functional description
The internal synchronous operation function is a special firmware/technology function,
which only expects increments from a master. The master can either be
• the X14 input or
•anyIPOS
plus® variable (virtual master drive), for example in conjunction with the
SBus or a virtual encoder.
2.2.1 Synchronizing
Time-controlled synchronizing has been implemented. A variation between the angle of
the slave drive and the master drive resulting from free running is reduced to zero.
In addition, a special type of synchronizing can be employed. The slave drive moves at
a synchronous angle to the master drive following a specified number of master incre-
ments (position-dependent synchronization). In this synchronization type, the slave
drive moves with a quadratic ramp.
2.2.2 Synchronous operation
Synchronous operation comprises various functions. For example, it is possible to
operate with a specified offset over a specific travel distance. An offset between the
master and slave drive comes into effect after a specified number of master increments.

2.2.3 Disengaging
Disengaging means the slave exits synchronous operation. This process can be
triggered manually by setting a system variable, or can be event-driven using an
external signal.

2State machine for internal synchronous operation
System Description
2.3 State machine for internal synchronous operation
The individual functions of internal synchronous operation are controlled using a state
machine. The state machine has the six main states shown in the following figure. See
also the chapter Operating principle and functions (page 16).

Controlling internal synchronous operation
System Description
2.3.1 Six main states
The state machine distinguishes between the six states Z0 to Z5. See also the chapter
Operating principle and functions (page 16).
•State Z0 = Free mode speed control
The slave drives moves in free-running mode with speed control. The reference to
the master drive can be stored in a difference counter.
•State Z1 = Free mode position control
The slave drive stops subject to position control and therefore does not drift out of
position. The reference to the master drive can be stored as desired.
•State Z2 = Engaging state
The slave drive is synchronized with the master drive using time or position control.
•State Z3 = Synchronous operation
The slave drive moves synchronously with the master drive.
•State Z4 = Offset
In synchronous operation, an offset can be set subject to time or position control.
•State Z5 = Disengaging state
The slave drive exits synchronous operation.
2.4 Controlling internal synchronous operation
Internal synchronous operation is controlled using IPOSplus® variables within the
IPOSplus® application program. All states can be viewed and set in a variable range from
H360 to H446, which is reserved for internal synchronous operation.
