    What to do if Baruffaldi DB21 Servo Drives show a Power Error?
    • D
      Diane SinghAug 21, 2025
      If Baruffaldi Servo Drives display a Power Error, it could be due to several reasons. A high current peak or an input voltage outside the specified range (check with a multimeter the voltage on the L1L2- L3 connector: 230V +10% / 400V +10%) could be the cause. Excessive regeneration during braking, possibly from a collision, can also raise the bus voltage. Another possibility is a motor or resolver problem. Ensure that the inertia and unbalancing applied to the turret does not exceed the stated limits and also the profile selected with the dipswitch is appropriate to the load condition. For motor or resolver issues, check motor and resolver resistance, or contact our service.

    What to do if Baruffaldi DB21 Servo Drives turret stays closed during unlocking [Li.12=Off, Li.13=On]?
    • J
      Jonathan ThompsonSep 3, 2025
      If, after issuing the unlocking command (Lo.15), the Baruffaldi Servo Drives turret remains closed (Li.13 = On) and the unlock proximity switch doesn't signal (Li.12 = Off) within 30 seconds, you should: * Check the functionality of the proximity switch. * Inspect the hydraulic/pneumatic circuit. * Check the electro valve/auxiliary relays connection.

    What to do if Baruffaldi DB21 Servo Drives turret stays unlocked during locking [Li.12=On, Li.13=Off]?

      If the Baruffaldi Servo Drives turret remains unlocked (Li.12 = On) and the lock proximity switch doesn't signal (Li.13 = Off) 30 seconds after the locking command (Lo.16), you should: * Check the functionality of the proximity switch. * Inspect the hydraulic/pneumatic circuit. * Check the electrovalve/auxiliary relais connection.

    What causes Time Out Rotation on Baruffaldi DB21 Servo Drives?
    • J
      jameshollyAug 31, 2025
      A 'Time out rotation' error in Baruffaldi Servo Drives indicates that after calling a zero research (hidden too), the zero proximity switch (Li.14) is always Off, meaning the turret hasn't reached the called position. To solve this, check the functionality of the zero proximity switch, verify the calibration of the zero cam, ensure there are no mechanical interferences preventing turret rotation, and inspect the wired connections between the drive and turret (M1 UVW and J2).

    Why is there no signal from lock proximity switch [Li.12=Off, Li.13=Off] on Baruffaldi Servo Drives?
    • K
      Kari FowlerAug 29, 2025
      If there's no signal from the lock proximity switch (Li.13) and the unlock proximity switch is also off (Li.12) after 30 seconds from the locking command (Lo.16) on Baruffaldi Servo Drives, check the functionality of the proximity switch. Remove the upper cover to verify that the movement of the pin is not hindered. Also, inspect the hydraulic/pneumatic circuit if present, check the turret setup made with the dipswitch, and check the drive configuration K2/K5.

    What to do if Baruffaldi DB21 Servo Drives show a Motor PTC error?
    • R
      ryanchandlerAug 28, 2025
      If Baruffaldi Servo Drives display a Motor PTC alarm, it indicates that continuity between pin 1 and 2 of J2 is not detected, suggesting the motor's temperature sensor (PTC) has detected excessive winding temperature. Ensure the ambient temperature near the motor is within allowed limits. If the alarm persists when the motor is cold, check the wires connecting the sensor (pins 1 and 2 of J2 on the board and the terminal turret).

    What to do if Baruffaldi DB21 show a Positioning Error?
    • G
      gjoyceAug 27, 2025
      If a positioning error occurs with Baruffaldi Servo Drives, it means the turret is locked in a position different from what was expected at the end of a position inquiry. The resolver value calculated differs from the final position resolver. Begin by verifying that the drive SETUP matches the turret in use (K2/K5/K3) at startup. Also, ensure the dipswitch is properly set according to the turret in use, considering the transmission ratio and the number of stations.

    What to do if Baruffaldi Servo Drives show a Resolver Malfunctioning error?
    • E
      Elizabeth ThompsonAug 25, 2025
      If your Baruffaldi Servo Drives system reports a Resolver Malfunctioning error, it means the signal from the resolver is either low or absent. You should: * Check the wiring of connector J2 and the connections in the terminal block signals on the turret. * Inspect the cable for integrity and continuity. * Ensure that the drive is correctly set for the motor in use.

    Why is my Baruffaldi DB21 turret not locked at the start up [Li.13=Off]?
    • M
      Michael BrownAug 23, 2025
      If the Baruffaldi Servo Drives turret isn't locked at startup (indicated by Li.13=Off), the alarm is activated because the drive commands the turret to lock, but the lock proximity switch isn't engaged. To resolve this, check the functionality of the proximity switch, inspect the hydraulic/pneumatic circuit, and verify the electrovalve/auxiliary relais connection.
