Control modules with digital setpoint interface for hydraulic/
analog linear drives HLA/ANA
The digital SIMODRIVE 611 HLA control module is designed to control and re-
gulate electro–hydraulic control values for hydraulic linear axes in conjunction
with SINUMERIK 840D. Up to two hydraulic axes can be controlled with the
module. An HLA module
is obtained by inserting the control module in the 50 mm wide universal empty
housing.
This module can be integrated directly next to the SIMODRIVE 611 drive group
both with the mechanical as well as the electrical interfaces, such as equipment
bus, drive bus and DC link busbars.
The HLA control module contains the control structures for an electronic control
loop with high dynamic response characteristics. The HLA control module gene-
rates the power supply for the control valves and shut–off valves from an exter-
nal DC power supply (e.g. SITOP power, refer to NC 60 Catalog) with a rated
voltage of 26.5V.
An analog axis with speed setpoint interface $10 V can also be controlled
using the HLA control module. In this case, an appropriate axis must be selec-
ted. As far as the coarse structure is concerned, the control operates as D/A
converter for the setpoint and communicates the position information from the
encoder to the position controller in the SINUMERIK 840D via the drive bus.
