Subject to change without notice
To detect all impermissible changes in the relationship between sine and cosine, vector
length monitoring is used. For the STL70S, the vector length must not deviate by more
than max. +/- 15% (see chapter 6.2. "HIPERFACE
8014120).
A deviation that is greater than +/-15% indicates a violation of the vector length limits.
The drive must respond to the error accordingly.
WARNING
The safe motor feedback system may be used only within the limits of the prescribed
and specified technical data, dimensions and tolerances of the dimensional drawings
and operating conditions, and the specified tightening torques must be complied with.
If used in any other way or if alterations are made to the device – including in the
context of mounting and installation – this will render void any warranty claims directed
to SICK AG.
The safe motor feedback system must only be used with a defined mounting kit
(2105618). The connection between the drive system and the safe motor feedback
system must have a rigid design.
The safe motor feedback system cannot support safety functions that are based on
the absolute position, which is transmitted to the RS 485 parameter channel, without
additional measures.
The mechanical coupling of the measurement system to the drive is relevant to safety.
Standard EN 61800-5-2, table D16, requires fault exclusion here concerning the
release of the mechanical connection between the measurement system and the drive.
The specifications for mounting the measurement system must be observed.
If such stimulations cannot be reliably ruled out in the application, suitable tests must
be carried out for the entire drive system.
The STL70S safe motor feedback system may be mounted, put into operation, checked,
maintained, or used only by qualified safety personnel.
Safety personnel is qualified when the following requirements are fulfilled:
•
Appropriate technical training of the personnel
•
Instruction of the machine operator in machine operation and the applicable
safety guidelines
•
Access to these operating instructions
WARNING
The supply voltage must be generated from PELV systems (EN 50178) and limited to 36
V DC by external means. The motor feedback system complies with protection class III
according to DIN EN 61140.
If the supply voltage is not generated from PELV systems, the user must take other
measures to ensure safe disconnection for live parts.
The monitoring unit at the safety inputs of the motor feedback system must be voltage-
tolerant up to the supply voltage (7-12 V DC) which is supplied to the motor feedback
system to not impact its own safety functions.
