Otherwise, it may cause a malfunction. Servo amplifier Servo motor Servo amplifier Servo motor The connection diagrams in this instruction manual are shown for sink interfaces, unless stated...
Page 6 CAUTION The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used for ordinary braking. For such reasons as service life and mechanical structure (e.g. where a ball screw and the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft.
Page 7 DISPOSAL OF WASTE Please dispose a servo amplifier, battery (primary battery) and other options according to your local laws and regulations. EEP-ROM life The number of write times to the EEP-ROM, which stores parameter settings, etc., is limited to 100,000. If the total number of the following operations exceeds 100,000, the servo amplifier may malfunction when the EEP-ROM reaches the end of its useful life.

Page 159: Auto Tuning
6. NORMAL GAIN ADJUSTMENT 6.3 Auto tuning 6.3.1 Auto tuning mode The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load to motor inertia ratio) in real time and automatically sets the optimum gains according to that value. This function permits ease of gain adjustment of the servo amplifier.

6. NORMAL GAIN ADJUSTMENT 6.3.3 Adjustment procedure by auto tuning Since auto tuning is enabled before shipment from the factory, simply running the servo motor automatically sets the optimum gains that match the machine. Merely changing the response level setting value as required completes the adjustment.
Page 162: Response Level Setting In Auto Tuning Mode
6. NORMAL GAIN ADJUSTMENT 6.3.4 Response level setting in auto tuning mode Set the response of the whole servo system by [Pr. PA09]. As the response level setting is increased, the track ability and settling time for a command decreases, but a too high response level will generate vibration. Hence, make setting until desired response is obtained within the vibration-free range.

6. NORMAL GAIN ADJUSTMENT 3) [Pr. PB08 Position loop gain] This parameter determines the response level to a disturbance to the position control loop. Increasing the value increases the response level to the disturbance, but a too high value will increase vibration of the mechanical system.
Page 167 6. NORMAL GAIN ADJUSTMENT (2) 2 gain adjustment mode 2 Use 2 gain adjustment mode 2 when proper gain adjustment cannot be made with 2 gain adjustment mode 1. Since the load to motor inertia ratio is not estimated in this mode, set the value of a proper load to motor inertia ratio in [Pr.

7. SPECIAL ADJUSTMENT FUNCTIONS 7.1.1 Machine resonance suppression filter POINT The machine resonance suppression filter is a delay factor for the servo system.
