The Q-Motion controller CPU controls and
synchronises the connected servo amplifi
-
ers and servo motors. A motion system
besides the controller CPU, also includes a
PLC CPU. Only after combining a highly
dynamic positioning control CPU and a
PLC, an innovative motion control system
is created.
While the Motion CPU controls complex
servo movements the PLC CPU is responsi-
ble for the machine control and the com-
munication.

Servo external signals interface
module Q172LX
The Q172LX input module is used in con-
junction 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 incorpo-
rated into the system.

Serial absolute synchronous encoder
interface module Q172EX and Q172EX-S2
The serial absolute synchronous encoder
interface module Q172EX is a Motion sys-
tem module for receiving and evaluating
up to two serial absolute-value encoders.
(Incremental encoders cannot be connected.)
Via an external encoder (Q170ENC) it is
possible to feed a setpoint source to the
Motion system, which inturn is pro-
grammed as a guide axis.
In addition to the interfaces 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

Manual pulse generator interface
module Q173PX
The Manual pulse generator interface mod-
ule Q173PX is used in a Motion system to
receivethesignalsofupto3externalincre-
mental encoders or manual impulse gener-
ators (hand wheels).
In addition to the inputs for the encoders,
the Q173PX has three digital inputs with
which the encoder signal counting proce-
dure can be started (Encoder start signal).
