Operation panel control ,external terminal control and COM control |
Frequency setting |
Keypad potentiometer setting , operation panel setting,. external terminal UP/DOWN setting, analog voltage signal or external potentiometer setting , analog current signal setting .terminal combination setting ,485 COM setting and so on. |
Input Signal |
Forward/Reverse signal\multi-speed signal \fault signal \ reset signal etc. |
Output signal |
Programmable relay\open collector output \Fault signal output. |
Multi-function analog and digital output terminal |
This can realize the output of frequency current and other physical quantity by output 0-10V or 0-20mA DC signal and 0-10KHz digital signal output. |
