Servo Drive/Amplifier/Controller Repair

A distinct feature of the Servo Drive is that it has a closed loop for the feedback (encoder/resolver/tacho sensor device to correct its output for precision motion control and accordingly it requires specialized electronics repair skills, knowledge and experience to repair these drives. Technicians at Ampione have aplenty of these by virtue of their training, exposure and experience in handling Servo Drive Repairs. Servo Drive can be:

  • AC Servo Drive

  • DC Servo Drive

The output devices in Servo Drive can be:

  • Silicon Control Rectrifiers (SCRs) for large pulses of power or

  • Transistrors (eg IGBTs) for smooth operation

Further the techniques to turn power on/off in output circuit are:

  • Linear – • Transistor always on • Amplitude of volts varied • High internal power dissipated
  • Power Width Modulation(PWN) - •Transistor either on or off • Amplitude of volts constant • Width of pulse varied • Low power dissipation
  • Power Frequency Modulation (PFM) - •Transistor either off or on • Amplitude of volts constant • Turn on time varied • Low power dissipation

The servo drive repairs, servo amplifier repair or servo controller repairs broadly involve: -

  • Servo Drive Input Circuit Repair

  • Servo Drive Control Circuit Repair

  • Servo Drive Firing/Output Circuit Repair

  • Servo Drive Feedback Circuit Repair
