Thus to achieve a 5 V output at 100 rps (6000 rpm) and 12-bit resolution the VCO input cur- rent must be: (100 × 4096)/(8500) = 48.2 µA Thus, R6 would be set to: 5/(48.2 × 10–6) = 103.7 kΩ The velocity offset voltage depends on the VCO input resistor, R6, and...
7. Please connect the braking resistor according to the wiring diagram. 8. Do not touch the terminals of VFD, it is very dangerous with high voltage. 9. Do not change the wiring or disassemble the terminals during power-on. 10.Do not modify the inverter without authorization. ...
