1.1 General Information
January 2010
Within the framework of standardization and adaptation to the machinery
directive 2006/42/EC, which will be binding as of January 1, 2010, the lettering
on certain components of the HEIDENHAIN inverter system will be changed.
This concerns the designation of the enabling signals SH1 ("Safe stop 1) and
SH2 ("Safe stop 2") on all. These designations are located on the front of the
HEIDENHAIN components mentioned below. Signal "SH1" is renamed to
signal STO A (Safe Torque Off - channel A) and the signal "SH2" in STO B
(SafeTorque Off — Channel B). These designations will be eventually
introduced in all technical documentation from HEIDENHAIN.
The following HEIDENHAIN components are affected by the change:
Non-regenerative compact inverters of the UEC 1xx, UE 1xx and UE 2xxD
series
Regenerative compact inverters of the UR 2xx series
UM 1xx(D) modular power stages
