Switching Servo Amplifier Assembly Adjustment

The 2596C is equipped with an independent servo drive amplifier assembly. The function of the servo amplifier assemblies is to drive the sequencer chain motor.

The servo amplifier assembly is located in a separate metal enclosures. The metal enclosure covers must be removed to access the servo amplifier assem- bly.

The sequencer chain is directly controlled by the chain drive control board., located in slot three of the I/O box.

The servo amplifier assembly is setup at the factory. If it is necessary to change the servo amplifier assembly, use the following procedure to adjust the replacement assembly.

Do not adjust the servo amplifier assembly to speed up the servo motor. The servo amplifier assembly is adjusted for best performance with the use of an oscilloscope. Adjustment of the servo amplifier assembly other than recommended can cause machine failure or loss of machine timing.

The purpose of the following procedures is to optimize the operating perfor- mance of the servo drive system.

The velocity command adjustment (CMD potentiometer) is required to scale the velocity command voltage. This adjustment scales the reference CMD voltage to the tachometer (TACH) feedback voltage for a specified motion profile.

TECHNICAL PUBLICATIONS

The lag compensation adjustment (LAG potentiometer) sets the proper

damping characteristics of the closed loop motion profile.

The offset adjustment (OFF potentiometer) compensates for small voltage offsets to maintain zero position.

To adjust the switching servo amplifier assembly, proceed as follows.

  1. Set the main circuit breaker (1CB) to the on position.
  1. Turn the palm switch to the start position.
  1. Remove the cover from the switching servo amplifier enclosure.
  1. Perform the LAG potentiometer adjustment as follows.

4a.    Turn the LAG potentiometer counterclockwise until a noticeable growling noise can be heard coming from the drive motor.

4b.    Turn the LAG potentiometer clockwise until the growling noise just stops.

4c.    Turn the LAG potentiometer clockwise an additional two turns.

  1. Perform the Offset potentiometer adjustment as follows.

5a.    Connect the ground lead of the multimeter to TP1-10 on the terminal block as shown.

5b.    Connect the positive lead of the multimeter to test point Vc.

5c.    Adjust the Offset (OFF) potentiometer to acheive a reading as close to 0 VDC as possible.

  1. Perform the Command potentiometer adjustment as follows. 6a.    Record the reading from the machine cycle counter.

6b.    Run the machine for sixty seconds, then record the new cycle counter reading.

6c.    Subtract the first reading from the new reading to determine the cycles per minute.

6d.    Adjust the Command (CMD) potentiometer as necessary and repeat steps 6a through 6c to acheive the correct speed based on the following machine configurations.

Machine with Expanded Range Verifier – 375 cycles per minute

Machine without Verifier – 417 cycles per minute
