The first is security. Programming non-cooperative industrial robots requires the use of disabling switches. This is when the operator is incapacitated, such as dying, losing consciousness, or leaving the control device
When, can automatically operate the switch. It is generally used as a form of failure safety, stopping the machine to avoid possible hazards. The demonstrator enables the user to change the robot's operating mode from the key
Switch between teaching mode and unrestricted operation to control the disabled switch.
For collaborative robots, there are also some emergencies that require the robot to stop working on its own. The demonstrator has the function of ensuring a safe and protective shutdown. All systems have the potential to fail, so operators need to
Have the ability to control the robot and switch its behavior mode to safe mode so that the human body can enter the work unit or move the robot to any desired location. The demonstrator is the most effective way to perform these operations
First, the basic principles of motor protector selection
At present, there is no unified standard for motor protectors on the market, and almost every manufacturer has its own model specifications. Manufacturers derive many variations to meet the needs of different customers
The wide variety of products for use brings a lot of inconvenience to the majority of users. Households should fully consider the actual needs of motor protection when selecting, 00-130-547 reasonable choice of protection functions and protection methods.
In order to achieve a good protection effect, 00-130-547 to improve the reliability of equipment operation, reduce unplanned parking, reduce the purpose of accident losses.
Second, the basic method of selection of motor protector
(A) Conditions related to selection:
The selection of motor protection has a reasonable relationship between the motor and the protector. The following provides several conditions and factors related to protection to provide a reference for users when selecting
1, motor: to understand the model specifications, motor functional characteristics, protection type, rated voltage, rated current, rated power, power frequency, insulation level, etc. These things are basically
It can provide a reference for users how to correctly choose and use the motor protector.
2, environmental conditions: mainly refers to room temperature, high temperature, cold, corrosion, vibration, wind sand, altitude, electromagnetic pollution, etc.
3, motor use: such as fans, pump air compressors, lathes, oil field pumping units and other different load mechanical characteristics, such as pump motor protectors, it should have underload function, when the water 00-130-
When the 547 pump finishes pumping water, the protector needs to give protection instructions.
4, the control system: the control mode has manual, automatic, local control, remote control, stand-alone independent operation, production line centralized control and so on. Starting methods include direct, step-down, star triangle,
00-130-547 Frequency sensitive rheostat, frequency, soft start and other starting modes.
5, other aspects: the user of the on-site production monitoring management is more casual or rigorous, abnormal shutdown of the severity of the impact on production.
There are many factors related to the selection of motor protectors, such as installation position, power supply situation, and coordination with the distribution system; Also consider whether to buy a new motor protector, or 00-
130-547 motor protection upgrade, or the improvement of accident motor protection; Also consider the difficulty of changing the motor protection mode and the degree of impact on production; A comprehensive test should be conducted according to the actual working conditions on site
Consider the selection and adjustment of motor protectors.
