Absolute System
Note
A complete absolute servo system includes an ASDA-A3 servo drive, an absolute motor, and a
backup battery box. The backup battery supplies power to the system so that the encoder
10
continues to operate even when the power is off. In addition, the absolute encoder can
continuously record the motor's actual position at any time, even when the motor shaft is rotated
after the power is off. The absolute servo system must be used only with an absolute motor.
If the servo is set up with other types of motors and the system is enabled, AL069 occurs.
When using an absolute motor connected to power, the motor speed should not exceed
250 rpm. When operating with the battery, make sure the maximum speed does not
exceed 200 rpm.
To determine whether your motor is an absolute type, check the model name as shown in the
following:
ECM-A3 series servo motor
ECMC series servo motor
Install the battery correctly on the encoder. One servo drive uses one single battery box; two servo
drives can share one dual battery box. Use Delta's encoder cable to connect to the battery box.
See the following section for the specifications of the battery box and its accessories.
