安全扭矩（Sto）
站的功能on is the most common and basic drive-
集成的安全功能。它确保没有扭矩
产生能量会继续影响电动机，
prevents unintentional startup.
Effect
This function is a mechanism that prevents the drive from
restarting unexpectedly, in accordance with EN 60204-1,
Section 5.4. Safe Torque Off suppresses the drive pulses
(corresponds to Stop Category 0 of EN 60204-1). The drive is
可靠的扭矩。该状态在内部受到监视
驱动器。
应用
斯托has the immediate effect that the drive cannot supply
任何扭矩产生的能量。可以在任何地方使用STO
由于负载扭矩，驱动器自然会停滞不前
或摩擦在少于短时间内或“沿海地区）
驱动器的下降将与安全无关。
Customer benefits
The benefit to the customer of using the Safety Integrated
与常规安全系统相反的功能STO
基于机电开关设备是没有单独的
components are needed and the costs incurred for the
单独组件的接线和维护可以
因此被保存。由于快速电子开关
时间，该功能提供的反应时间比
包括机电的传统解决方案
components.
安全扭矩（Sto）
安全停止1（SS1）
The SS1 function causes a motor to stop rapidly and safely
并将电动机切换到无扭矩状态之后
到达停滞，即通过激活Sto。
Effect
SS1功能可以安全地停止驱动器
使用EN 60204-1，停止类别1。
被选中，驱动器制动器沿快速自动刹车
stop ramp and automatically activates the Safe Torque Off
and Safe Brake Control functions (if configured) when the
参数化安全延迟时间到期。
In firmware version V4.5 and higher, an additional variant
可以使用SS1（SS1E）。在这种情况下，选择SS1确实
not initiate autonomous braking of the drive, but starts the
safe delay timer instead. The higher-level controller remains
控制必须将驱动器带到一个的设定点
standstill within this time.
应用
当安全性时，使用SS1函数
relevant incident, the drive must stop as quickly as possible
然后过渡到Sto州（例如紧急情况
停止）。因此，它被用来将大的离心质量带到
a stop as quickly as possible for the safety of the operating
personnel, or to brake motors at high speeds as quickly
as possible. Typical applications include saws, grinding
machine spindles, centrifuges, winders, and storage and
检索系统。
Customer benefits
The targeted stopping of a drive by means of SS1 reduces
the risk of danger, increases the productivity of a machine,
并允许减少机器中的安全间隙。
The principle is to bring the drive actively to a standstill as
opposed to using the STO function on its own. Complex
容易穿着的机械制动器
通常需要制动电动机。
