TEMPFAULT – Temperature fault (bit 5, BooleanT)
When the temperature inside the gripping module exceeds 70° C, this bit is set. It is recommended to
stop the gripping module and only start it again after it has significantly cooled down. If necessary, the
heat dissipation of the gripping module should be checked.
The bit is automatically reset when the temperature falls below 68° C.
Temperatures exceeding 70° C may lead to malfunctions and to permanent damage of the
gripping module.
FAULT – Device fault (bit 4, BooleanT)
When this bit is set, the gripping module is in error state. Information on the cause of the fault can be
obtained by checking the active system events (cf. chapter 8.3) or by evaluating the event log.
For troubleshooting, see chapter 9.9.
HOLDING – Holding (bit 3, BooleanT)
Shows whether a part has been gripped. This is the case when the base jaws of the gripping module are
blocked within the specified gripping range, i.e. between the parameterized RELEASE Limit and NO PART
Limit, and the gripping force has been built up.
NO PART – No part found (bit 2, BooleanT)
When the base jaws of the gripping module reach the parameterized NO PART Limit or are moved be-
yond it, no part has been detected and this bit is set.
RELEASED – Part released (bit 1, BooleanT)
When the base jaws of the gripping module reach the parameterized RELEASE Limit or are moved be-
yond it, the part is considered released and this bit is set.
IDLE – Gripping module inactive (bit 0, BooleanT)
When this bit is set, the gripping module is inactive and force-free. No gripping commands can be exe-
cuted.
For information on activating the gripping module, see chapter 9.6.1.

Acyclic Process Parameters and System Commands
For the operation of the gripping module, several acyclic process parameters can be set and queried. These
process parameters comprise identification, configuration, and diagnosis data, as well as system commands.
These data are addressed via index (8 or 16 bit) and subindex (8 bit). Some of the parameters are specified
by the IO-Link standard; other parameters are device-specific or determined by the manufacturer. All param-
eters are defined in the IO-Link Device Description (IODD) file.
