7-2-2 Terminal Function
Terminals Descriptions
TB2
Vin
Voltage input, to adjust the amplitude of output voltage at terminal A/O and
terminal B/O. It also provides a 5 V voltage to support line driver’s signal.
Vin voltage range: 8–24 V, Max: 24 V.
A/O, B/O
Output signal for the push-pull voltage frequency division.
Default: Output amplitude is about +24 V. Use SW3 to disable the internal
default power. Required input power through Vin-GND port (i.e. output
voltage’s amplitude)
Vin voltage range: 8–24 V, Max: 24 V.
Push-Pull Voltage Output
Max. output frequency: 100 kHz
Supports frequency division output, the frequency division range: 1–31.
GND
Common ground terminal connecting to the host controller and the motor drive.
AO,
AO
,
BO,
BO
Output signal for the line driver frequency division.
Line Driver RS422
Max. output frequency: 150 kHz
Supports frequency division output, the frequency division range: 1–31.
TB1
VP
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.
0 V
Common power terminal for encoder
A, A ,
B,
B ,
Z, Z
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
U, U ,
V,
V ,
W, W
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
JP1
Ground Terminal
Connect the motor drive power supply to ground. Supports PG shielding.
SW1 Switch between power for the encoder (5V / 12V).
SW2
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.
SW3
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).
