IPOSplus® positioning and sequence control system
Considerable relief for the higher-level PLC
In fact, the positioning and sequence control system
integrated in MOVIDRIVE® can often take a great
deal of load off the master PLC, or maybe even replace it.
Reducing the central control offers SEW customers
significant potential savings in terms of hardware and the
complexity of electrical installation.
The programming work is divided between the PLC and inverter
control. However, users must familiarize themselves with the
system. This includes getting to know IPOSplus®
if you want to make effective use of what it has to offer.
- The IPOSplus® sequence control system
makes it possible to run a user program, disregarding
any encoder feedback or the selected control mode (VFC,
CFC, SERVO).
- In conjunction with encoder feedback, the IPOSplus®
positioning control provides a high-performance
point-to-point positioning capability.
- The program is run independent of encoder feedback and
operating mode.
- MOVIDRIVE® continues to run the user
program even if the unit develops a malfunction
(troubleshooting is possible in the user program).
- IPOSplus® can run several user
programs/tasks simultaneously, independent of one
another. Tasks can be interrupted using interrupts.
- The user programs can contain several hundreds of
program lines.
- Easy-to-use and comprehensive control options for IPOSplus®
units.
- Access to all available options:
- Extensive communication options:
-
- System bus (S-bus)
- RS-485
- RS-232 (with interface adapters USS21A, UWS11A,
UWS21A)
- Fieldbus interfaces
- Processing of binary and analog input/output signals.
- Positioning with adjustable travel speed and
positioning ramps.
- Presetting for position, speed and torque control
loops with minimized lag error.
- Absolute encoder processing.
- 1024 32-bit variables are available in the IPOSplus®
program. Of these variables, 128 can usually be stored
protected against power failure.
- With IPOSplus®, all inverter parameters
can be read and written via communication commands.
- 2 touch probe inputs.
- Ramp types:
-
- Linear
- Sine
- Square
- Bus ramp
- Jerk-limited
- Electronic cam
- I-synchronous operation
- Status and monitoring functions:
- 9 reference travel types.
- The following functions can be changed during
movement:
-
- Target position
- Travel speed
- Positioning ramp
- Torque
- "Endless positioning" is possible.
- Override function.
- The following technology functions can be controlled
with a virtual encoder:
- Programming in the compiler also offers:
-
- Program creation in a standard language
- Symbolic variable names
- Possibility of creating program modules that can
be used again in other projects
- Clear, modular and structured programming is
possible
- Different programming techniques for loops
- Compiler control using preprocessor commands
- Standard structures
- User-defined structures
- Standard functions
- Debugger for troubleshooting
- Extensive options for making remarks (remarks
are only stored in the PC)
- Programming in the assembler offers:
- Setpoint selection. Depending on the hardware and the
required setpoint, the following options are available
for the specification:
-
- Analog setpoints
- Fixed setpoints
- Fixed setpoints and analog setpoints
- Motor potentiometer
- Master/slave operation with SBus
- Master/slave operation with RS-485
- DRS setpoint (only with the DRS11 option)
- Fieldbus/fieldbus monitor setpoint (only with
fieldbus interface option)
- IPOSplus® position setpoint
