The controller cards are inserted into the card plug-in slot of the compact servo drive
module KW. The entire control of the drives including all monitoring and communication
is realized via the digital signal processor on the card.
The controller cards KW-R03 and KWR03P offer 2 additional card connectors, the controller card KW-R06 offers one
additional card connector for option cards. The option cards are connected using a
bus connector in the appropriate position on the controller card.
Functions:
• Control motor brake
• Electronic gear
• Probe function (actual position
encoder/square wave pulse)
• Number of probe inputs according
SERCOS
• Homing cycle
• Spindle positioning
• Change of operating mode
• Transfer of the parameter set
• Digital/analogue speed control
• Absolute/relative positioning
Realtime Ethernet
With the controller card KW-R06, AMK has created a new platform for outstanding
controller performance in the AMK drive system: With EtherCAT/VARAN as realtime Ethernet
interface, a fast system
bus is available which is predestined for high dynamic positioning tasks. So more
than 100 drives with setpoints can be used synchronously. Integrated filters avoid disturbances by noise or cyclic
influence. If no absolute encoders are used, the commutation can be effected by software using a micro
movement.
Furthermore, the controller card has an option slot with which the system can be
expanded through digital I/O’s.
Functional safety
The KW-R07 is similar to the KW-R06. Additionally safe drive solutions up to
PL e according to EN ISO 13849-1 can be realized. The control of the safety
functions is carried out by safe I/O’s or via FSoE by a safety PLC.
Safe stop functions
• STO - Safe Torque Off
• SOS - Safe Operating Stop
• SS1 - Safe Stop 1
• SS2 - Safe Stop 2
Safe movement functions
• SLS - Safely Limited Speed
• SDI - Safe Direction
• SSR - Safe Speed Range
ACC-Bus
The KW-R03 is a controller card with full functionality. For connection to a control
and to additional participants, the CANopen (ACC bus) interface is available.
Up to 32 drives with setpoints can be used synchronously. The controller card offers two option slots for expanded
functionality.
The KW-R03P adds PLC functionality.
The KW-R04 is similar to the KW-R03 without the encoder connection X131.
