Type and specification of the inverter
It can keep constant output voltage automatically in case of change
of mains voltage.
“Digging machine” feature, which can limit the torque
automatically and prevent frequent over current tripping during the
running process; the close loop vector mode can implement torque
control.
It can conduct safety detections on the peripherals upon power-on,
including earth and short circuit detections.
It can realize the function that multiple inverters share the DC bus.
Programmable key: Select the command channel switching/forward
and reverse rotations/jog operation/up and down.
Three types of channels: operation panel reference, control terminal
reference and serial communication port reference. These channels can be
switched in various modes.
There are totally eight types of frequency sources, such as digital
reference, analog voltage reference, analog current reference, and serial
port reference etc.
These frequency sources can be switched in various modes.
There are five digital input terminals, one of which can be used as
high-speed pulse input. (The number of digital input terminals can be
expanded to ten) It can be compatible with active PNP or NPN input
mode.
There are two analog input terminals, one of which can be used only as
voltage input, while the other can be used as voltage or current input. (It
can expand one voltage input terminal)
There is one high-speed pulse output terminal (can be selected as open
collector mode), with square wave output of 0kHz to 50kHz. It can output
such physical parameters as setting frequency and output frequency.
One digital output terminal (can be expanded to two) One relay output
terminal (can be expanded to two) One analog output terminal (can be
expanded to two), with optional 0//4mA to 20mA or 0/2V to 10V. It can
realize the output of such physical parameters as setting frequency and
output frequency.
It can display the parameters
protection function
It can implement power-on motor short-circuit detection, input/output
phase loss protection, over current protection, over voltage protection,
under voltage protection, over heat protection and overload protection.
