Q-Motion CPU
The Q-Motion controller CPU controls
and synchronises the connec ted servo
amplifiers and servo motors. A motion
system besides the controller CPU, also
includes a PLC CPU. Only after c ombining
a highly dynamic positioning control
CPU and a PLC, an innovative motion
control s ys tem is created.
While the Motion CPU controls
large-scale servo movements the PLC
CPU is responsible for the machine con-
trol and the communication.

Servo external signals interface module
Q172LX
The Q172LX input module is used inconjunction
with a Q Motion CPU to capture external servo
signals.
Up to 8 axes can be evaluated per module. In
this way, cam-switching values, limit switching
positions, stop positions and operating modes
can be easily incorporated into the system.
앬
32 address points for 8 axes for each 4 inputs

Bipolar inputs for positive and negative logic
앬
Galvanic isolation of the inputs by means of
photocoupler

Serial absolute synchronous encoder
interface module Q172EX and Q172EX-S2
The serial absolute synchronous encoder inter-
face module Q172EX is a Motion systemmodule
for receiving and evaluating up to two serial
absolute-value encoders. (Incremental encoders
cannot be connected.) Via an external encoder
(MR-HENC / Q170ENC) it is possible to feed a
setpoint source to the Motion system, which
inturn is programmed as a guide axis.
In addition to the inter faces for the signals of
two absolute value encoders, the Q172EX has
two digital inputs with ultra-rapid
responsetimes.
앬
Transfer rate of 2.5 Mbit per second
앬
Resolution of 14 bit MR-HENC /
18Bit Q170ENC
앬
Voltage-failure security of the absolute values
by means of built-in buffer battery
앬
Shortest response times of < 0.4 ms
앬
Modular extension possible
Manual pulse generator interface module
Q173PX
The M anual pulse generator interface module
Q173PX is used in a Motion system to receive
the signals of up to 3 external incremental
encoders or manual impulse generators (hand
wheels).
In addition to the inputs for the encoders, the
Q173PX has three digital inputs with which the
encoder signal counting procedure can
bestarted (Encoder star t signal).
