Safety technology
The pulse board in the drive controller generates the pulse patterns required
by the power board to produce the rotary field. The pulse patterns in the SD6
are transferred from the control board to the power board via the ST6 safety
card.
If the safety function is active, a reliable pulse inhibit prevents the pulse pattern
from being transferred to the power board. The power board is unable to
generate a rotary field and the motor is torque-free.
If the safety function is active, pulse patterns are directed to the power board
and the motor can be operated.

This is equivalent to the safety function
Safe torque off
(STO) in accordance
with DIN EN 61800-5-2:2007. This type of shutdown is designated as
Stop
category 0
in DIN EN 60204-1:2006.
MC6 Motion Controller
The development of the new MC6 Motion
Controller and its integration into the STOBER
product portfolio opens up new solutions for
drive technology, especially for complex
functions with demanding requirements for
timing and precision.
SD6 and Motion Controller MC6 are either
connected to each other via EtherCAT or via
CANopen.
Information
Detailed information about the MC6 Motion Controller can be found
in the corresponding manual (see section 1.2 Further
Safe Torque Off – ST6
Included in the standard design.
The ST6 accessory makes it possible to use the
"Safe Torque Off" (STO) safety function in the
SD6 drive controller in safety-relevant
applications according to EN ISO 13849-1.
