Y20 Sfty obsrvation: FB speed err 0004 (Axis name)
Details
Actual rotation speed of the motor is exceeding the speed that has been set with speed monitoring
parameter during the speed monitoring mode.
The name of the axis with an error is displayed.
Remedy
Correct the speed observation parameter and the sequence program.
Restart the NC.
Y20 Door signal: Input mismatch 0005 Door No.
Details
Door state signals on the NC side and the drive side do not match. It may be caused by the followings:
- Cable disconnection
- Damaged door switch
- Damaged NC or servo drive unit
Remedy
Check the cable.
Check the door switch.
Restart the NC.
Y20 No speed observation mode in door open 0006 Door No.
Details
The door open state was detected when the speed monitoring mode was invalid.
The causes may be same as the ones for 0005 (Door signal: Input mismatch). Also the sequence
program may not be correct.
Remedy
Correct the sequence program.
Restart the NC.
Y20 Speed obsv: Para incompatible 0007 (Axis name)
Details
Two speed monitoring parameters are not matched at the rising edge of the "speed monitor mode"
signal.
The name of the axis with an error is displayed.
Remedy
Correct the relevant parameters so that the two speed monitoring parameters match.
Restart the NC.
Y20 Contactor welding detected 0008 Contactor No.
Details
Contactor welding was detected.
Some contactors take a while to be shutdown after the servo ready is turned OFF, and the servo ready
was turned ON in the meantime.
The contactor showing unusual move will be indicated as a bit.
bit0 : MC_dp1
bit1 : MC_dp2
Remedy
- Make sure that contactor's auxiliary B contact signal is output correctly to the device set on "#1330
MC_dp1(Contactor weld detection device 1)" and "#1331 MC_dp2(Contactor weld detection device
2)".
- If welding, replace the contactor.
- Restart the NC.
