Correct wiring and parameter settings for relay terminals
first step:
Prepare one frequency converter and one 24V indicator light.
Step 2: Introduction to the characteristics of relay terminals.
Because relay terminals are transistor outputs, and TA, TB, and TC are analogous to the collector, base, and emitter of a transistor. The EN600 frequency converter defaults to normally open contacts for TA and TC, and normally closed contacts for TB and TC. It can connect to AC 220V and DC 24V.
Next, we will conduct an experiment to verify the response of the indicator lights to the various states of the frequency converter.
1. Connect the 24V power supply in series to the TA port, then connect one end of the 24V indicator light in series to the TC port, and the other end of the 24V indicator light in series to the COM port.
2. When we manually set the inverter to report a certain fault, since the relay terminals TA and TC are defaulted to fault output, TA and TC will conduct after the fault is reported, and the 24V indicator light will light up.
The relay terminals can also be configured for other functions. For example, if we set the relay terminal function to power-on output of the stepper, after starting the frequency converter, it will also connect TA and TC, thereby illuminating the 24V indicator light.
Step 3: Setting relevant parameters.
The relay terminal corresponds to the inverter parameter F09.04. The default value is 22, which represents an inverter fault output.
The specific function of this relay terminal can be modified according to the site requirements. For example, when F09.04 is changed to 06, it represents the inverter shutdown command indication, etc.
Because the experiment above involved manually malfunctioning the inverter, it is necessary to define terminal X3 as an external device fault, with parameter F08.20 set to 22, where 22 represents an external device fault input.
REV/FWD operating mode selection
REV/FWD operating mode, which is the forward and reverse rotation operating mode of the frequency converter.
This mode has multiple functions, one of which is to effectively control the emergency stop of the frequency converter, thereby protecting equipment and personal safety. The forward and reverse operation modes are mainly divided into two-wire control mode and three-wire control mode.
Two-wire control modes : Two-wire control mode 1, Two-wire control mode 2, Two-wire control mode 3.
Three-wire control modes : Three-wire control mode 1, Three-wire control mode 2.
The inverter's default operating mode F08.26 is 0, which represents two-wire control mode 1.
F08.26 0 Two-wire control mode 1
F08.26 1 Two-wire control mode 2
F08.26 2 Two-wire control mode 3
F08.26 3 Three-wire control mode 1
F08.26 4 Three-wire control mode 2
