Cartões opcionais 

A range of option cards are for individual function enhancement, which can be inserted into the inverter‘s controller card.

Functions:
•  Fieldbusses
•  PLC for Motion Control and machine control
•  Encoder interfaces
•  I/O extension

I/O Extension KW-EA2
This option card paves the way for a low-cost enhancement of the KE/KW system with digital inputs and outputs, which can also be used to control motion profiles.

Features:
•  12 digital 24V inputs in compliance with VDI 2880
•  8 optically isolated 24V outputs each rated at 100mA
•  Short-circuit monitoring of the outputs
•  Bit information within the drives configurable for outputs
•  Triggering of various drive functions configurable through inputs
•  With “Configurable Control PLC”, the I/O can be used as PLC inputs and outputs.

Encoder interface KW-EN1

This option card enables connection of a second sinusoidal encoder measuring system. This means that both a highresolution, linear scale for position feedback and a sinusoidal encoder system for speed control and commutation can be connected to one KW.

Features:
•  Absolute encoder with actual position encoder in the form of Endat®2.1
•  Ext. 24 V incoming encoder supply
•  Probe input through 1 digital input 24V

Encoder interface KW-SSI

The option card KW-SSI provides the actual position value through a SSI interface for a
higher-level controller.

Features:
•  Actual position value is cyclically updated depending on the SERCOS cycle time
•  Minimal updating rate = 500μs
•  Actual position value can be sampled by higher-level controller in a cycle of >=1ms
•  KW-SSI works as cycle slave
•  Independent of plug-in slot
•  Automatic recognition

Fieldbus KW-EC1

The option card KW-EC1 facilitates communication between a higher-level controller (EtherCAT master) and the KW module (EtherCAT slave) using the SoE (servo drive over EtherCAT) profile.

Features:
•  EtherCAT protocol with servo drive profil (SoE)
•  Synchronous data and parameters according to SERCOS (IDs)
•  Min. cycle times (500 μs)
•  Optional setting of addresses via rotary coding switches

Fieldbus KW-SC1

The interface card KW-SC1 transforms the drive into a SERCOS interface® slave. This
slave is based on the SERCOS interface® slave Version V 1.02. in compliance with
DIN EN/IEC 61491.

Features:
•  SERCOS class C
•  Communication cycle time minimal 0.5 ms
•  Transfer rate up to 16Mbit/s
•  Broadcast Message to all drives available

Fieldbus KW-PB1

The interface card KW-PB1 PROFIBUS-DP allows communication between a PROFIBUS Master and the drive via AMK fieldbus protocol AFP for drive commanding.

Features:
•  Connection of the inverter to a PROFIBUS-DP MASTER in compliance with DIN 19245,    part 3
•  Maximum 32 slaves per line (can be enhanced to max. 122 slaves with repeater)
•  Baud rate 12 Mbit/s
•  Address assignment via rotary encoding switch
•  Max. 48 input and 48 output bytes
•  AFP driver component for Siemens S7 SPS available

PLC for machine control KW-PLC2

PLC according IEC 61131-3. For all complex machine control functions including visualization as well as the execution of axis-specific tasks. In addition, the option card offers a hardware synchronous CANopen interface.

Features:
•  CANopen in accordance with DS301 version 4.01.
•  Additionally CAN BUS MASTER or SLAVE
•  Hardware synchronized signal scanning, jitter < 1μs
•  Comprehensive AMK Motion Control
•  2 fast probe inputs with a resolution of up to 200 ns
•  RS422 MODBUS interface for data exchange between PLC and an external operator
   panel/visual display unit
•  584 kByte program memory
•  128 kByte data memory
•  32 kByte RETAIN memory
