Sensor Control Word (G1_STW)
G1_STW is one of the two control words cyclically written to the NR60E2. Only bits 15 through 11 are used
by the NR60E2.
Figure R7.1 G1_STW Format
Bit 11: Home position mode –
This bit is used in conjunction with bit 12, Request set/shift of home posi-
tion . A 0

1 transition on bit 12 initiates a preset/offset of the current position value. In PROFINET
documentation, a preset is known as an Absolute Preset, and an offset is known as a Relative Preset.
The preset/offset value is named “Preset Value” and is programmed with an acyclic data transfer as
parameter 65000. When this bit equals zero, the parameter is treated as a preset value, and the internal
position offset is modified to bring the current position value to the preset value. When this bit equals
one, the parameter is treated as an offset value, and this value is added to the internal position offset.
In this case, the new position value is offset from its old position value by the value stored in the Pre-
set Value parameter.
Bit 12: Request set/shift of home position –
This bit is used in conjunction with bit 11, Home position
mode . A 0

1 transition on this bit initiates a preset/offset of the current position value. The preset/
offset value is named “Preset Value” and is programmed with an acyclic data transfer as parameter
65000. The state of bit 11 determines how the Preset Value is applied to the present position. This bit
should remain set until the NR60E2 responds by setting G1_ZSW.12 to a “1” to signal that the posi-
tion has been successfully preset or offset.
Bit 13: Request absolute value cyclically – When this bit is set to “1”, the G1_XIST2 signal will transmit
the absolute position value unless an error condition exists. If this bit is reset to “0”, the G1_XIST2
signal will transmit a value of zero unless an error condition exists.
Bit 14: Activate parking sensor –
When this bit is set to “1”, the NR60E2 enters the parked state.
G1_XIST1 values must not be considered valid while the NR60E2 is parked. All actual errors and all
error messages are cleared while the NR60E2 is parked and removing the NR60E2 from the network
will not cause an alarm in the PLC controller.
Bit 15: Acknowledging a sensor error – This bit is a handshake response from controller. The controller
must set this bit to “1” to acknowledge the Requirement of error acknowledgement detected bit from
the NR60E2. (G1_ZSW.11) The NR60E2 will respond by resetting the Requirement of error
acknowledgement detected bit. The sensor error bit, G1_ZSW.15, will remain active as long as an
error exists.
This reference chapter lists the formats of the cyclic data signals transmitted to
and from the NR60E2. This chapter also lists the five PROFINET telegrams sup-
ported by the NR60E2 that use these data formats. Telegrams are well defined
data packets that are transferred between the Controller and the NR60E2.
