PCI-1285/1285E User Manual 14
3.5 Position Latch [LTC]
It is a general purpose input pin which is used to latch the simultaneous position
information. Users can read the position counter by programming. For detailed infor-
mation, refer to chapter 6.
3.6 Servo Ready Signal [RDY]
It is a general purpose digital input which is used to check the servo ready status
from servo drive connection. For example, you can check the status before any com-
mand is issued. Users can also use this RDY as general purpose input for other
usages.
3.7 Home Position [ORG]
Home position is to define the original position or home signal for each axis. refer to
chapter 6 for programming settting.
3.8 In-Position Singal [INP]
The In-Position range (or deviation) is usually defined by servo drive. When the
motor moves and converges within this range (or deviation), the servo driver will
send the signal out to indicate that the motor is in the defined position.
3.9 Servo Error & Alarm [ALM]
This input is from servo drive which will generate the alarm signal to indicate any
operation error.
3.10 Encoder Input [ECA+/-, ECB+/-, ECZ+/-]
When the feedback encoder signals arrive, connect ECA+/ECA- to phase A of
encoder output. It is a differential pair. The same rule is for ECB+/- and ECZ+/-. The
default setting of PCI-1285/1285E is quadrature input (4xAB phase). The following
diagram shows the interface circuit for one channel:
Figure 3.7 Circuit Diagram of Encoder Feedback
In the circuit diagram above, PCI-1285/1285E use high speed photo coupler for isola-
tion. The source's encoder output can be differential mode or open-collector mode.
And the maximum acceptable 4xAB phase feedback frequency is about 10 MHz.
