S7-1200 Programmable controller
774 System Manual, V4.2, 09/2016, A5E02486680-AK
Invalid direction of motion
-
16#002E The selected motion direction is not
allowed.
• Adjust the motion direction and
restart the command.
• Adjust the allowed direction of rota-
tion in the technology object config-
uration under "Extended parameters
> Mechanics". Restart the com-
mand.
16#002F A reversing motion is not possible
with the selected motion direction.
Reference switch/encoder zero mark not found
Stop with emer-
gency stop ramp.
16#0033 Error in the configuration, hardware
or installation of the encoder or at the
homing switch.
• Connect a suitable device.
• Check the device (I/Os).
• Compare the configuration of HW
Config and the technology object.
Alarm message from encoder
Remove enable.
16#0001 - Check the device with regard to func-
tion, connections and I/Os.
Hardware error at encoder
16#0036 Error during reading of encoder abso-
lute value
Compare the encoder type in the drive
or encoder parameter P979 with the
configuration data of the technology
16#0037 Zero mark monitoring of the encoder Encoder reports error in zero mark
monitoring (fault code 0x0002 in
Gx_XIST2, see PROFIdrive profile).
Check the plant for electromagnetic
16#0038 Encoder is in "Parking" state
• Search for the cause of the error in
the connected drive or encoder.
• Check whether the error message
was possibly triggered by a com-
missioning action at the drive or en-
coder.
16#0040 PROFIdrive: Encoder at bus failed
Check the device with regard to func-
tion, connections and I/Os.
16#0041 PROFIdrive: Signs of life of encoder
Range violation of the position
Remove enable.
16#0039 Range violation in positive direction Home the axis to a valid actual value
range.
Range violation in negative direction
16#003B
The change of the actual position in a
position control clock cycle is greater
than the modulo length.
Adjust the modulo length of the em-
ployed encoder.
