Encoder Input [ECA+/-, ECB+/-, ECZ+/-]
When the feedback encoder signals arrive, ECA+/ECA- will connect to phase A of
encoder output. It is a differential pair. The same rule is for ECB+/- and ECZ+/-. The
default setting is quadrature input (4xAB phase). The following diagram shows the
interface circuit for one channel:
Figure 3.4 Circuit Diagram of Encoder Feedback
In the circuit diagram above, high speed optocoupler is used for isolation. 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.
3.7
Emergency Stop Input [EMG]
When emergency stop input signal is enabled, the output of the drive pulse for all
axes will be stopped.
Figure 3.5 Circuit Diagram of Emergency Stop Input Signal
This signal should be used in combination with external power DC 24 V. The
response time of circuitry should take about 0.25 msec because of the delay of photo
coupled and RC filter.
3.8
External Power Input [VEX]
External power is necessary for all input signals of each axis. Applying DC 24 V volt-
age as required.
3.9
Activate Servo ON [SVON]
This SVON is to generate a digital output to activate the servo drive to be ready for
move status.
Note!
Do not connect the VEX pin directly to an inductive load.
