Jog operation Jog operation frequency: 0.0Hz~maximum frequency
Jog acceleration/deceleration time: 0.1s~3600.0s
Simple PLC & multi-step speed operation It can realize a maximum of 16 multi-step speeds running via the built-in PLC or control terminal
Built-in PID Built-in PID control to easily realize the close loop control of the process parameters (such as pressure, temperature, flow, etc.)
Automatic voltage regulation Keep output voltage constant automatically when input voltage fluctuating
Control Function Torque limit “Rooter” characteristics, limit the torque automatically and prevent frequent over-current tripping during the running process
Wobble frequency control Multiple triangular-wave frequency control, special for textile
Timing/length/ Timing/length/counting control function
counting control
Over-voltage & over-current stall control Limit current & voltage automatically during the running process, prevent frequent over-current & over-voltage tripping
Fault protection function Comprehensive protections include over-current, over-voltage, under-voltage, overheating, default phase, overload, shortcut, etc., can record the detailed running status during failure & has fault automatic reset function
I/O terminals Input terminals Programmable digital inputs: MI1~MI6, HDI can be set as high speed pulse input terminal
Programmable analog inputs: AI1, AI2, AI3: compile with both 0~10V & 4~20mA.
Output terminals Programmable digital outputs: 2 relay outputs, 2 open-collector outputs, HDO can be set as high speed pulse output terminal.
Programmable analog outputs: AO1, AO2: compile with both
0~10V & 4~20mA.
Communication terminals Standard RS485 communication interface, support MODBUS-RTU communication protocol
Human machine interface LED display Display frequency setting, output frequency, output voltage, output
current, etc. Two lines display
