●
In the case of IndraDrive Cs, IndraDrive C, IndraDrive M and
IndraDrive ML, the selection can take place via one channel,
alternatively by means of
–
a passive safety unit with an isolated conventional (non-solid-state)
normally closed contact (designed in compliance with SIL3), e.g.,
safety switching device for emergency stop, safety door monitor,
etc.
In addition, the fault exclusion (short-circuit with other signals /
potentials) in the wiring (considering IEC 61800-5-2: 2007, table D.
1 or ISO 13849-2: 2008, table D.4) is required, or
–
by means of an active safety unit with plus-switching OSSD output
(e.g., safety control units, laser scanners, etc.).
In addition, the fault exclusion (short-circuit with other signals /
potentials) in the wiring (considering IEC 61800-5-2: 2007, table D.
1 or ISO 13849-2: 2008, table D.4) is required.
●
The dynamization of the safety function selection takes place
alternatively by means of
–
the OSSD dynamization of the active safety unit or
–
the dynamization outputs at the X49 terminal connector of the
optional safety technology module "L3" or "L4" in the case of
control by passive safety units.
●
It is possible to set up a zone by connecting up to 25 drives in parallel.
●
Online dynamization of the outputs and interrupting circuits
●
Short reaction time [18 ms (108 ms with IndraDrive ML)]
●
The state of safety function "Safe Torque Off" is displayed via parameter
"P-0-0106, Operating status STO/SBC".
The following parameters are used in conjunction with the safety function
"Safe Torque Off":
●
P-0-0101, Configuration STO/SBC
●
P-0-0106, Operating status STO/SBC
The following diagnostic messages can be generated in conjunction with the
safety function "Safe Torque Off":
●
A0011 STO/SBC active
●
E8027 STO/SBC while drive enabled
●
F3134 Dynamization time interval incorrect
●
F8027 STO/SBC while drive enabled
●
F8300 Dynamization pulse width incorrect
●
F8301 Error when checking selection signals
●
F8302 Error when checking switch-off channels STO/SBC
●
F8303 System error STO/SBC
With the safety function "Safe Torque Off" activated, the display of the drive
controller's control panel shows "STO".
The optional safety technology modules "L3"/"L4" feature two 24 V inputs for
dual-channel selection and two dynamization outputs for operation at passive
safety units.
