3 Hardware
Typical fields of application are:
•
Servo axes in handling devices
•
Independent positioning axes in ma-
chines
•
Auxiliary axes in machine tools
SIMODRIVE POSMO CD/CA
SIMODRIVE POSMO CD (without mains
infeed) and SIMODRIVE POSMO CA (with
mains infeed) are complete converter and
control units. They provide both a digital
speed setpoint interface (Motion Control
with PROFIBUS DP) and a comprehensive
integrated positioning functionality.
The connection of the supply voltage is provided via a mains infeed of
600 V DC (with CD) or directly via a 3AC 400 V - 480 V power supply (with CA).
The 24 V DC electronic power supply is generated distributed in the device.
Typical fields of application are:
•
High-performance servo applications in packaging, textile and woodworking
machines
•
Feed axes on machine tools
Analog drive systems
Drives with an analog setpoint interface can be connected to PROFIBUS DP via
the interface module ADI4 (Analog Drive Interface for 4 Axes). The interface mod-
ule provides the following features:
•
PROFIBUS-DP interface
•
4 servo interfaces
Inputs: TTL/SSI for incremental or absolute measuring systems
-
Outputs: ±10V analog
-
Drive-specific digital input/output signals
