Applicable encoders:
1. Open collector output encoder application: Use one pull-up resistor for each set of input current 5–15
mA. Refer to the table below for resistor specifications. If open collector input voltage uses 5V or 12V
external power, see the PG wiring Figure 2 below.
EMED-PGABD-x
Line Driver RS422
Max. output frequency: 150 kHz
Supports frequency division output, the frequency division range: 1–31.
Power output for encoder
NOTE
Use SW1 to set output voltage amplitude
Voltage: +5 ± 0.5 V or +12 ± 1 V
Current: 200 mA max.
Common power terminal for encoder
Incremental-type encoder signal input terminal
Types of input signal: line driver, voltage, push-pull, open collector
NOTE
Different input signals need different wiring methods. See the user manual
for wiring diagrams.
Max. input frequency: 150 kHz
Absolute-type encoder signal input terminal
Types of input signal: line driver, voltage, push-pull, open collector
NOTE
Different input signals need different wiring methods. See the user manual
for wiring diagrams.
Max. input frequency: 150 kHz
Ground Terminal
Connect the motor drive power supply to ground. Supports PG shielding.
Switch between power for the encoder (5 V / 12 V).
Offline Detection Switch. Switch to the Line-D side to enable offline detection for the
Line-D input signal. Switch to OPEN-C side to disable offline detection function for the
OPEN-C input signal.
Power supply switch for frequency division. Switch to INP side to provide 24 V power for
internal use. Switch to EXP side to provide 24 V power for external use (client).
5 V Suggested pull-up resistor: above 150–520ohm, 1/2 W
12 V Suggested pull-up resistor: above 600–2Kohm, 1/2 W
