(2) Add and subtract keys: used to increase or decrease data. The most common symbols are Delta or_, or_. Some converters are equipped with transverse shift keys (or keys) to speed up digital changes.
What operating keys are equipped with the frequency converter?
Various frequency converters have different appellations for operation keys and operation keys. In summary, there are the following categories:
(1) Mode conversion key: used to change the working mode. Common symbols are: MOD (Mode), PRG (Program), etc.
(2) Add and subtract keys: used to increase or decrease data. The most common symbols are Delta or_, or_. Some converters are equipped with transverse shift keys (or keys) to speed up digital changes.
(3) Read-out and write-in keys: when programming, they are used for "read-out" and "write-in" data codes. Read out and write two functions, some with the same key to complete, and some with different keys to complete. Common appellations are: READ, WRITE, SET, DATA, etc.
(4) Operating keys: Under the working mode of keys, they are used for "running" and "stopping" operations. First and foremost: RUN (work), FWD (forward), REV (reverse), STOP (discontinuity), JOG (click) and so on.
(5) Reset key: It is used to restore the frequency converter to normal condition after fault trip. The name of the key is RESET.
(6) Digital keys: Some converters are equipped with digital keys such as "0-9" and decimal point "...". When setting the data code, you can type the data you need directly.
How many ways does the frequency converter work?
There are two main types:
(1) Key operation mode: that is to say, key operation is used to control the operation and interruption of the motor.
(2) External control mode: that is, through external control signals such as potentiometer: 0 ~10V voltage signal, 4 ~ 20mA current signal to complete the operation of the motor.
In what way is it programmed on time?
