To add customized functionality, a series of optional plug-in cards are available for the controller card of the inverter.
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.
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 for our controller crads R03 and R03-P 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.
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 for our controller crads R03 and R03-P provides the actual position value through a SSI interface for a higher-level controller.
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
The option card KW-EC1 for our controller crads R03 and R03-P facilitates communication between a higher-level controller (EtherCAT master) and the KW module (EtherCAT slave) using the SoE (servo drive over EtherCAT) profile.
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
The interface card KW-SC1 for our controller crads R03 and R03-P 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.
SERCOS class C
Communication cycle time minimal 0.5 ms
Transfer rate up to 16Mbit/s
Broadcast Message to all drives available
The interface card KW-PB1 PROFIBUS-DP for our controller crads R03 and R03-P allows communication between a PROFIBUS Master and the drive via AMK fieldbus protocol AFP for drive commanding.
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 our controller crads R03 and R03-P. 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.
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
