Controller DH.21B/41B
Introduction
Performance class
CCU advanced
The "CCU advanced" performance class is intended for application modules with single-
axis and multi-axis functionality and fast response times. The following application
modules are available:
• Single-axis functionality:
– Speed specification
– Cam positioning
– Bus positioning 6 process data
– Single-axis universal module
• Multi-axis functionality:
– SyncCrane
– Energy-efficient SRU
3.3 Controller DH.21B/41B
3.3.1 Features
Two types of DH.21B/41B controllers are available:
•As option card DH.21B/41B for MOVIDRIVE
®
B and MOVITRAC
®
B inverters (only
DHE21B/41B) and for MOVIAXIS
®
servo inverters
•In stand-alone housing DH.21B/41B UOH.1B prepared for installation on a
mounting rail.
3.3.2 Device types
Three types of DH.21B/41B controllers are available, which differ in the fieldbus inter-
faces:
3.3.3 Overview of communication interfaces
The DH.21B/41B option is equipped with numerous communication interfaces.
The two system bus interfaces CAN 1 and CAN 2 are primarily used for connecting and
controlling several inverters and for integrating decentralized I/O modules.
You can operate this machine module on a higher-level controller using the integrated
fieldbus interface.
An operator terminal (e.g. DOP11B) or a MOVIMOT
®
gearmotor with integrated
frequency inverter is connected to the RS485 interfaces.
SEW drives and SEW I/O modules with EtherCAT interface can be connected to the
SBUS
PLUS®
system bus interface.
