17:X140-wire break A wire break was detected at 
X120.
• Check the connected cable (encoder or SSI connec-
tion).
• Check the power supply of the SSI encoder or the 
source that simulates the SSI signals.
• Make sure that the settings of the SSI master are 
matched to the SSI encoder or the source that simu-
lates the SSI signals.
• Check whether a device is correctly parameterized 
as the source of the SSL signals in the SSI Motion-
bus.
• Check whether the devices in the SSI Motionbus 
boot up together.

18:X120-Timeout No cycle signal was detected 
from the SSI master.
• Check the connected cable.
• Check the power supply of the SSI master.
• Make sure that the settings of all devices in the SSI 
Motionbus are matched to each other.
• Check whether a device is correctly parameterized 
as the SSL master in the SSI Motionbus.
• Check whether the devices in the SSI Motionbus 
boot up together.

19:X4 double tr. Different positions are frequently 
determined at X4 during dual 
transfer.
• Check the connection and shielding of the encoder 
cable.
• Reduce the electromagnetic interference.
