Simple test mode is active

Details
Smart safety observation target axis (the parameters "#51101 SF_Disable" = 0 / "#51301 SF_SDisable" =
0) is defined as a hypothetical axis (the parameter "#51015 safe_drv_test" = 1). In this case some alarms
fail to occur, thus avoid this setting while a drive unit is being connected.
NC system is set to a simulation mode (the parameter "#1168 test" = 1 ). During this mode some alarms
fail to occur, thus do not use this mode while a safety I/O unit is connected.
Remedy
Connect MDS-E Series drive to all the axes subject to safety observation, set the parameter ("#51015
safe_drv_test" = 0) and then turn OFF and ON the power.
Connect a safety I/O unit, set the parameter ("#1168 test" = 0) and then turn OFF and ON the power.
