How to make the motor stop when the inverter is urgent, and how to wire the emergency stop switch of

Generally, the inverter needs to set two parameters:

First, parking mode: slow down parking;

It should be noted that: the inertia of the load, if the load inertia is very small, then, the emergency stop can be achieved by the inverter setting alone, if the load inertia is large, it is best to add braking resistance, or braking unit + braking resistance, this is according to the power of the inverter, in general, and below, only add braking resistance, if it is greater, you need to add braking unit and braking resistance.

The motor itself has inertia, so when it receives the stop order, it can not stop immediately, which is also normal, and the solution to this problem can be considered from two aspects: first, it is to use a motor with mechanical braking function, that is, the mechanical locking function; Second, you can consider using the DC braking function of the inverter.

Reduced downtime! Generally, if it is not set, the factory default is 10 seconds. You can set it to 1s.

However, if you want to use this function, you must add a resistor behind the inverter, because the feedback current is very large.

When an emergency occurs at the work site, if it is necessary to immediately stop the equipment carried by the inverter, the inverter is first set up for emergency stopping, and the inverter is connected to the inverter through the upper computer, and the emergency stop button is installed on the site of the motor equipment to control the inverter equipment, and the operation authority is set on the spot.

The power is not too large, and it is very easy to buy an electromagnetic brake motor. I put the original connection to the motor terminal.

The wire ends of the brake coil are removed and controlled by another relay that is controlled by the digital output of the frequency converter. The main reason for using a relay is to protect the digital output of the inverter (although the capacity of the digital output is sufficient).

The parking time is smaller, however, the running speed of the motor is more parking has a certain proportion, and the running speed is high, and the parking time is longer.

You can use an electromagnetic brake motor hehe.

This is the digital input terminal of the inverter, your emergency stop switch is actually a button with self-locking, and a digital input terminal group directly connected to the inverter can be used, and then the letter line needs to be set to the emergency stop function of the group of terminals you are connected to.

If the emergency stop function of the inverter is used, a contactor should be added to the AC380V input of the inverter.

The power contactor needs to be disconnected when the emergency stop button is pressed.

The specific details of various inverters are different, but they all have signal terminals, and STOP to the ground is.

Set the inverter to "operation instructions are controlled by external terminals", and then connect the FWD terminal and COM terminal on the inverter to the normally closed contact of the emergency stop button.

If there is also a reversal, the emergency stop button can be equipped with two sets of normally closed buttons, and the other set can be connected to the REV terminal and COM terminal of the inverter.

In this way, whether it is in the forward light or the reverse, after pressing the emergency stop button, the inverter has no operation command, and the output will be stopped.

If it is necessary to deal with the situation that requires an emergency stop, it is recommended to set the deceleration time of the inverter as short as possible without affecting the process and damaging equipment. At the same time, set the parking mode as the deceleration and braking mode, and do not use the free parking mode. The braking frequency can also be set a little higher, so that the equipment can stop quickly in the event of an emergency stop.

Hello, add an emergency stop button outside the inverter, and introduce the button signal into the DI terminal of the inverter, and then define this DI terminal as the emergency stop terminal inside the inverter after the potato ball. On the outside, connect a close stop press book loose button, use normally closed contacts, connect any input point of the inverter, and compile (anti-logic) within the state hand, that is, the power is normal, and the power is lost and stopped, so that the stop button can be prevented from being used frequently, and lose its use, and the normally closed contact has a monitoring effect. As soon as this button is tapped, the inverter immediately performs an emergency shutdown.

How to control the inverter with the emergency stop button Hello dear,!<

Add an emergency stop button outside the inverter, introduce the button signal into the DI terminal of the inverter, and then define this DI terminal as the emergency stop terminal inside the inverter, connect a land fuel tight stop button outside, use the normally closed contact fiber, connect any input point of the inverter, and compile (anti-logic) internally, that is, the power is normal, and the power is lost and stopped, so that the emergency stop button can be prevented from being used often and losing its use, and the normally closed contact has a monitoring effect. As soon as this button is tapped, the inverter immediately performs an emergency shutdown. M0 M5 find an idle port and add an emergency stop switch between the destruction of GND.

Then enable the port you connect to in the menu, and finally configure the definition function you give to this port should be to select harmonic parking to have a braking resistor,,, I hope it can help you! <>
