Option K82 Terminal interface for STO and SS1
Option K82 “Terminal interface for Safety Integrated
功能STO和SS1”提供了方便的客户
interface for enclosed drives (terminal strip X41) that offers:
• 3rd party certification of compliance with the relevant
安全标准
• A wide voltage range for input signals 24 VDC - 230 VAC
• Contact for checkback signal
The operator control element must be a safety switch in
accordance with the relevant standards, or a certified
安全控制器。
该电路可以用于STO或
SS1功能：
•Sto（立即阻止逆变器，海岸停止）或
•SS1（快速坡道向下； STO将在A后激活
（参数化）时间延迟）。
Note that if SS1 is activated when the motor is stationary,
使驱动器安全的STO信号只会激活
坡道延迟延迟时间。检查信号
确认STO有效时。

What is the difference between options K82 STO/SS1 and
N57 Emergency OFF category 0 respectively N59/N60
紧急停止类别1？
STO and Emergency OFF cat. 0 both result in a coast to stop,
SS1和紧急停止猫。1两者都导致快速
ramp down with subsequent removal of power. All these
designs incorporate safety relays.
Differences between these options are the standards and
满足的规范。安全整合
功能包括与设计有关的严格要求，
wiring, testing and start-up, and associated certification
在各个阶段的合格人员。有
requirements for redundancy in certain circuits and
components. These requirements apply to components
and circuitry both inside the drive enclosure as well as
在植物外面。
The requirements met with Emergency OFF/Emergency
STOP are not as extensive.
