Code SV0453: α Pulsecoder soft disconnection

Also shown as: SV0453 (30i/31i/32i), SV0453 (0i-D) Action: 1: This alarm is issued when a separate phase A/B scale is used. Check if the phase A/B detector is connected correctly. 2: This alarm is issued when the position feedback pulse variation is small relative to the velocity feedback pulse variation. This means that this alarm is not issued when a semi-full is used. Check if the separate detector outputs position feedback pulses correctly. If position feedback pulses are output correctly, it is considered that the motor alone is rotating in the reverse direction at the start of machine operation because of a large backlash between the motor position and scale position. #7 #6 #5 #4 #3 #2 #1 #0 No. 1808 (FS15i) TGAL No. 2003 (FS16i) TGAL (#1) 1: Uses the parameter for the soft disconnection alarm detection level. No. 1892 (FS15i) Soft disconnection alarm level No. 2064 (FS16i) Standard setting 4: Alarm issued for a 1/8 rotation of the motor. Increase this value. 3: This alarm is issued when synchronization between the absolute position data sent from the built-in Pulsecoder and phase data is lost. Turn off the power to the CNC, then detach the Pulsecoder cable then attach it again. If this alarm is still issued, replace the Pulsecoder. 3.TROUBLESHOOTING AND
