Carrier frequency: 1.0K ~ 15.0KHZ

Functional characteristic

Frequency set mode:digital set, analog quantity set, serial communications set,

SPD, PID set

PID control function

SPD control function: eight-stage speed(16-stage speed for the F103 version)

Swing frequency control function

Non-stop function for momentary interruption

Restarting function of rotational speed tracking: realizing the non-impact of

smooth start-up of the motor in rotation

Automatic voltage regulation function: when the network voltage changes, it can

maintain the constant output voltage automatically

Providing multi-fault protection function: overcurrent, overvoltage, undervoltage,

overtemperature, phase loss, output short-circuit, overload, etc.

Operating environment
