EMG stop signal device illegal

Details
The channel No. or station No. of the emergency stop signal device (set by parameters) does not coincide with
any contact point (channel/station No. specified by the safety I/O assignment parameters RIO CH No and RIO
Station No.) of the safety I/O unit. The screen displays the index No. of the incorrectly set emergency stop sig-
nal device.
0001: EMG_Dev1_ch to EMG_Dev1_bit
0002: EMG_Dev2_ch to EMG_Dev2_bit
Remedy
Change the channel, station or bit No. of emergency stop signal device to be one of the contact points of
the safety I/O unit. And then turn OFF and ON the power.
When you change the setting of emergency stop signal device channel No. (EMG_Dev1_ch /
EMG_Dev2_ch) to 0, and turn OFF and ON the power, the designation of emergency stop signal device is
disabled, so this alarm is cleared.
V04

Safe IO assign para setting er

Details
Safety I/O device assignment parameter is incorrect.
The safety I/O device assignment parameter of the connected safety I/O unit is not set.
The safety I/O device assignment parameter is set for any disconnected safety I/O unit.
The set channel No. or station No. is overlapped.
Remedy
Make sure which safety I/O unit is connected, set the safety I/O device assignment parameters, and then
turn OFF and ON the power.
V04

Safety I/O param inconsistent

Details
There is a discrepancy between the PLC side parameter (I/O allocation setting) and CNC side parameter (safe-
ty I/O allocation).
The setting of "Top XY" on the PLC side is different from "DI(DO) dev No." on the CNC side.
The number of registered safety signal units is different between PLC and CNC sides.
Remedy
Correct the parameters to be consistent between PLC and CNC. After that turn OFF and ON the CNC power.
V05

SLS speed error

Details
During SLS observation, the command/FB speed has exceeded the safely-limited speed(*) and has not
dropped below the speed limit within the SLS detection delay time (set by parameter).
The screen displays the name of axis of this error.
(*)Safely-limited speed = SLS speed tolerance x SLS speed override / 100
Remedy
This error can be cancelled by the safety reset signal while motor speed is under SLS limit.
If the SLS speed tolerance or SLS speed override (set by parameter) is lower than the assumption, change
the parameter setting and turn OFF and ON the power.
If the SLS detection delay time (set by parameter) is shorter than the assumption, change the parameter
setting.
Check the safety ladder to make sure that SLS speed tolerance and SLS speed override are changed in
a timely manner.
