    Why Baruffaldi DB-21 Servo Drives turret is not locked at startup?
    • E
      evan83Sep 6, 2025
      If the Baruffaldi Servo Drives gives a command for locking the turret at startup, and the lock proximity switch (Li.13) is off, the alarm is activated. Check the functionality of the proximity switch, the hydraulic/pneumatic circuit, and the electrovalve/auxiliary relais connection.

    Why am I getting an overvoltage error on my Baruffaldi Servo Drives?
    • S
      Shawn PadillaAug 22, 2025
      An overvoltage error in Baruffaldi Servo Drives can occur when the input voltage is too high or due to excessive regeneration during braking, causing the bus voltage to rise. Use a multimeter to check the voltage on the L1-L2-L3 connector, ensuring it's within the range of 220V +10%. Also, verify that the inertia and unbalancing applied to the turret do not exceed the stated limits and that the profile selected with the dipswitch is appropriate for the load condition.

      If the Baruffaldi Servo Drives turret remains unlocked (Li.12 = On) after 30 seconds from the locking command (Lo.16) and there is no signal from the lock proximity switch (Li.13), check the functionality of the proximity switch. Also, check the hydraulic/pneumatic circuit and the electrovalve/auxiliary relais connection.

      If there's no signal from the lock proximity switch on Baruffaldi Servo Drives after 30 seconds from the locking command (Lo.16), and the unlock proximity switch is also Off (Li.12), check the functionality of the proximity switch. Remove the upper cover and verify that the movement of the pin is not hindered. Check the hydraulic/pneumatic circuit. Check the turret setup made with the dipswitch and the drive configuration K2/K5.

    What causes undervoltage on Baruffaldi Servo Drives when the turret is unlocked?
    • K
      Kimberly EstradaSep 1, 2025
      Undervoltage on Baruffaldi Servo Drives when the turret is unlocked indicates that the power supply voltage on the M1 connector is less than 80V. Check the voltage on the L1-L2-L3 connector with a multimeter. If the alarm occurs during rotation, the power transformer might not be powerful enough; ensure it is at least 2KVA.

    How to resolve a zero search error on Baruffaldi DB-21 Servo Drives?
    • A
      Andrew VincentAug 30, 2025
      This alarm occurs when, at the end of zero search, the turret is locked and the resolver value differs from the value stored during the resolver acquisition sequence. If the turret has reached station N°1, repeat the acquisition of the position resolver. Otherwise, remove the back cover of the turret and, with the turret locked in station N°1, verify that the mechanical position of the zero camshaft matches the picture.

    What does motor PTC alarm mean on Baruffaldi DB-21?
    • M
      michelle05Aug 29, 2025
      The Motor PTC alarm on Baruffaldi Servo Drives activates when continuity is not detected between pin 1 and 2 of J2. This indicates the temperature sensor (PTC) of the motor senses 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 board and the terminal turret).

    What to do if Baruffaldi DB-21 calls a non-existing position?
    • T
      Thomas HillAug 27, 2025
      If Baruffaldi Servo Drives requests a position higher than the number of stations provided, check the setting of the dipswitch. Also, check the code management of the position in the PLC, the wiring of connector J1, and reset the drive setup.

    How to fix resolver malfunctioning on Baruffaldi DB-21 Servo Drives?
    • A
      andersonalexandraAug 27, 2025
      If you encounter a resolver malfunctioning alarm on Baruffaldi Servo Drives, it means the signal from the resolver is either low or absent. Check the wiring of connector J2 and the connections in the terminal block signals on the turret. Inspect the cable for integrity and continuity. Also, ensure that the drive is set to the motor in use.

    Why Baruffaldi DB-21 Servo Drives shows a positioning error?
    • S
      Sandra RogersAug 26, 2025
      A positioning error with Baruffaldi Servo Drives happens at the end of a position inquiry if the turret is locked in a position different from what was expected. The resolver value, based on the acquisition value, differs from the final position resolver. At startup, check that the drive SETUP matches the turret in use (K2/K5/K3). Ensure the dipswitch is properly set according to the turret in use, considering the transmission ratio and number of stations.
