IPOS® Positioning and sequence control
The basic functions and options of IPOSplus® units ensure that the program is no longer only an open-loop speed controller.

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.
IPOSplus® features
Technical data
Encoder resolution:
MOVIDRIVE® X15, motor encoder
MOVIDRIVE® X14, external encoder
MOVIDRIVE® X62, absolute encoder (including absolute encoder from HIPERFACE®)
IPOSplus® always operates with 4096 increments / motor revolution
Prerequisites: Encoder resolution of 512, 1024 or 2048 pulses/motor revolution (any other encoder resolutions are not permitted) or resolver
Maximum program length/program memory:
MOVIDRIVE® A (without MCH): 4 kByte
MOVIDRIVE® MCH: 8 kByte
MOVIDRIVE® B: 16 kByte
1 kByte equals approx. 200 to 250 assembler commands
Command processing time:
MOVIDRIVE® A:
Task 1: 1 assembler command/ms
Task 2: 2 assembler commands/ms
MOVIDRIVE® B (the total in task 1 and task 2 ≤ 12 assembler commands/ms):
Task 1: 1 to 10 assembler commands/ms
Task 2: 2 to 11 assembler commands/ms
Task 3: free computing time
Interrupts:
MOVIDRIVE® A:
1 interrupt triggered by timer, error or touch probe interrupts task 1.
MOVIDRIVE® B:
As MOVIDRIVE® A, an additional 4 variable interrupts that interrupt task 2 and task 3.
Variables:
MOVIDRIVE® A: 512/MOVIDRIVE® B: 1,024, of these 128 (0 to 127) are protected from loss in case of a power failure in each case. Exception: MDS, MDV, MCS, MCV with the electronic cam technology option. Here, 16 variables (0 to 15) are protected from loss in case of a power failure in each case.
Value range: - 231 to +(231 - 1)
Touch probe inputs:
2 inputs, processing time 200 µs
Sampling interval of analog inputs:
1 ms
Sampling interval of binary inputs:
MOVIDRIVE® A: 5 ms
MOVIDRIVE® B: 1 ms
Binary inputs/outputs:
MOVIDRIVE® A:
MOVIDRIVE® B:
DIO option:
DIP option:
6 inputs/3 outputs
8 inputs/6 outputs
8 inputs/8 outputs
8 inputs/8 outputs
Analog inputs/outputs:
MOVIDRIVE®:
DIO option:
1 input (0 to 10 V, ±10 V, 0 to 20 mA, 4 to 20 mA)
1 input (0 to 10 V, ± 10 V, 0 to 20 mA)
2 outputs (± 10 V, 0 to 20 mA, 4 to 20 mA)
