Introduction to the Safety Functions

12.1.1 Safety Functions
Safety functions are built into the SERVOPACK to reduce the risks associated with using the
machine by protecting workers from the hazards of moving machine parts and otherwise
increasing the safety of machine operation.
Especially when working in hazardous areas inside guards, such as for machine maintenance,
the safety function can be used to avoid hazardous moving machine parts.
You can implement the following four safety functions depending on the Safety Module that you
use.
Hard Wire Base Block
(HWBB and SBB)
Safety Base Block with
Delay (SBB-D)
Safe Position Monitor
with Delay (SPM-D)
Safe Speed Limit with
Delay (SLS-D)
*1.
The Active Mode Function stops the motor according to the speed reference that is preset in a parameter in the
SERVOPACK when the safety request input signal turns OFF during SBB-D or SPM-D.
The Active Mode Function is not a safety function in the applicable standards. Keep this in mind when you
design the system.
*2.
A Safety Module (optional) must be connected to use this function. Refer to the following manual for application
procedures.
