SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
5.2 System environment
The SINUMERIK 840D and HLA module are supplied via the device bus
from the SIMODRIVE mains supply module or the SIMODRIVE monitoring mod-
ule (may only be installed in conjunction with a mains supply module as an ex-
tended power supply). No provision has been made for any other type of volt-
age supply and failure to use the supply provided could damage the unit.

monitoring module, as well as recommended circuits, technical data and setting
