Input Filters
Selectable spike and low pass filters
Solid State Motor Control
CW/CCW open collectors (opto-isolators) for use as discrete control inputs to the inverter
for motor operation.
Failsafe operation
If input signal exceeds configured input range. Selectable and adjustable.
Feedback signals/Output
0 to 20 mA, 4 to 20 mA
0 to 5 Vdc, 1 to 5 Vdc with 250 ohm resistor; (0 to 16 Vdc with 800 ohm resistor)
Slidewire Emulation
Provides output voltage ratiometric to shaft position and potentiometric to supply voltage
(1 to 20 Vdc) without a slidewire. Emulates a 100 ohm to 1000 ohm slidewire. 10 mA
output maximum.
Isolation
Input signal, output signal and power are isolated from each other.
Load Requirement (4-20)
Current Out — 0 to 1000 ohms
