The PowerFlex 525 AC drives include embedded Safe Torque-Off as a standard feature. Safe Torque-Off is an optional feature for the PowerFlex 40P, 70, 700H, 700S, and 750-Series AC drives, which also support Safe Speed Monitor functionality. Additionally, you can configure drives without a safety option using the MSR57P Safety Relay.
2015-10-26The standard mentions even more limitations, but the bottom line is this Safe operating distance is a safeguarding method of last resort. Besides, with todays safeguarding technology, few applications qualify. The safeguarding standards also account for the use of a safe speed, in which the ram moves at a slow speed.
2015-6-16Safe work practices - Grinding machine ToolWork rest The work rest must be securely clamped and the gap between the tool rest and wheel must not be more than 3mm. The work rest height must be on the horizontal center line of the machine spindle.
Safe control of pneumatics also includes releasing energy, reducing pressure and force, limiting speed, stopping or blocking motion, and moving only in a safe direction. Much of whats in the standards above is beyond the scope of this article. However, safe control of a machine includes use of proven components with long life expectancy.
2019-11-1The maximum operating speed is the maximum peripheral speed at which the grinding wheel can be safely used. It is indicated in unit of meters per second ms. The maximum operating speed depends on the types of wheels. The standard maximum operating speeds for types of
2019-3-11The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm about 30 to 35 msec. High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
2012-11-6Power press brake technology is continuously evolving, and this standard reflects the most commonly used and time-tested state of the art at the time of its approval Standards Update from Omron Automation and Safety, FREMONT, CA - The newly revised standard, ANSI
This standard applies to new, modified or rebuilt power driven machines, not portable by hand, used to shape andor form metal or other materials by cutting, impact, pressure, electrical or other processing techniques, or a combination of these processes. This can be a single machine, a machine tool or a machine tool systems.

2003-3-15In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machines speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.
2017-10-1This Foreword is not a part of the American National Standard Safety Code For the Use, Care and Protection of Abrasive Wheels, B7.1-1970 In 1917 the Grinding Wheel Manufacturers and the Machine Tool Builders began to recognize a need for codification and standardization of the basic requirements of safe operation of abrasive grinding wheels.
2019-12-4Once recommended drill speed is found, align the belt pulleys to the desired speed o See chart below for pulley alignment designated for desired speed. This chart can also be found in the Drill Press User Manual p. 15 o Unplug the machine o Open the head cover of the machine
The standard is written in this manner because conditions vary greatly from one facility to the next. What is a safe speed limit at one facility may not be safe in another environment. Even within any given facility safe speed can change from one moment to the next. If the floor becomes wet for example, speeds must be reduced considerably.
2018-5-9Safety system monitoring can include machine speed, direction of rotation, stopping and standstill. When executing a safety function, e.g. monitoring a crawl speed that deviates from the expected value i.e. is too fast, the safety system detects this deviation and actively returns machine operation to a safe state

2012-9-10Calculating the minimum safe mounting distance is vital to ensure worker safety, while excessive mounting distances use up valuable floor space and also can increase the time required to service machinery, which in turn reduces throughput. This article will explain how to calculate safe mounting distances for many types of safeguards.
