• The SINUMERIK FM--NC is installed in the CPU tier
of the SIMATIC S7--300. The 200 mm wide, fully encapsulated
module has the same external design as the
SIMATIC S7--300 modules.
• The SINUMERIK 840D is installed as a compact module in the
SIMODRIVE 611D converter system. It has the same
dimensions as a 50 mm wide SIMODRIVE 611D module. The
SINUMERIK 840D comprises the NCU module and the NCU
box.
• The SINUMERIK 810D has the same design as the SIMODRIVE
611D with a width of 150mm. The following components are
integrated: SIMATIC S7--CPU, 5 digital servo drive controls and
3 SIMODRIVE 611D power modules.
1. Control operating area
2. The control incorporates a self--diagnosis program and test
routines for servicing: Status, alarm and service displays.
Digital modules are signal transducers for binary process signals.
Position and lead/pitch values can be programmed in inches in the
machining program. The control is set to a basic system regardless
of the programmable unit of measure (G70/G71).
Differential Resolver Function NC function which generates an
incremental zero offset in AUTOMATIC mode in conjunction with an
electronic handwheel.
When the CNC axes are in the constant motion phase, automatic
drift compensation is implemented in the analog speed control.
(SINUMERIK FM--NC).
• SINUMERIK FM--NC has an analog +10V interface to the
SIMODRIVE 611A converter system.
• The SINUMERIK 840D control system is linked to the
SIMODRIVE 611D converter system via a high--speed digital
parallel bus.
