4 DEDICATED DEVICES
• Bit 3: Allowance value of speed deviation over
If the speed deviation exceeds the allowance value of speed
deviation (factor of "Safety observation error (error code: 113)"), this
bit will be turned ON.
• Bit 4: External auxiliary pulse position deviation over
If the difference between cumulative external auxiliary input pulse, or
safety encoder and motor encoder value exceeds the allowance
value (factor of "Safety observation error (error code: 114)"), this bit
will be turned ON.
Allowance value is equivalent of 1.75 pulse in the external input
pulse, or 1 pulse of safety encoder.
• Bit 6: Standstill monitoring position command over
If the command position has changed during standstill monitoring
(factor of "Safety observation error (error code: 115)"), this bit will be
turned ON
• Bit 7: Speed monitoring error detection
If one of the bits 0 to 6 continues to be ON over the speed
monitoring error detection time, this bit will be turned ON.
• Bit 8: Axis stop time over (Motion CPU only)
During speed monitoring, if the axis is in standstill status without the
small oscillation for one hour or more ("Safety observation error
(error code: 120)"), this bit will be turned ON.
• Bit 9: Speed monitoring unaccepted request (Motion CPU only)
If the speed monitoring starts with the safety observation error
("Safety observation warning (error code: 210)"), this bit will be
turned ON
• Bit A: Speed error detection check time out (Motion CPU only)
If a prior diagnosis is not completed normally at speed monitoring
start-up ("Safety observation error (error code: 116)"), this bit will be
turned ON
• Bit B: Small oscillation warning detection (Motion CPU only)
If the safety observation warning related to the small oscillation is
occurred ("Safety observation warning (error code: 20 )"), this bit
will be turned ON
• Bit C: Small oscillation error detection (Motion CPU only)
If the safety observation error related to the small oscillation is
occurred ("Safety observation error (error code: 121)"), this bit will
be turned ON
• Bit E: Servo axis data error detection (Motion CPU only)
If the inconsistency between the number of pulse per motor
revolution, the movement amount per motor revolution, and the
motor encoder resolution is detected, in the safety observation
function parameter ("Safety observation error (error code: 102)"),
this bit will be turned ON.
• Bit F: Speed monitoring parameter inconsistency detection
If the inconsistency between safety speed, the safety motor speed,
and the movement amount per motor revolution is detected ("Safety
observation error (error code: 101)"), this bit will be turned ON.
