1.5.1 Series Digital Amplifiers
The
Series servo amplifier integrates a power supply with the switching circuitry.
Therefore, can provide a compact amplifier that is 60% smaller than conventional models.
In fact, the
Series amplifier has the same height and depth as the RX3i and Series 90-30
modules. This allows efficient panel layout when using the DSM314 motion controller.
The amplifier is designed to conform to international standards.
Emerson offers three communication interfaces for the
Series amplifiers: pulse width
modulated (PWM), Servo Serial Bus (FSSB), and I/O Link Interface. Only the pulse width
modulated (PWM) interface may be used with the DSM314 module. The PWM interface
utilizes the standard servo communication protocol. Position feedback is communicated
serially between the DSM controller and the motor mounted serial encoder.
Series Servo Motors
The
Series Servomotors are built on the superior technology of the
Series servos. They
incorporate several design innovations that provide the best possible combination of high
performance, low cost, and compact size. Ratings of 0.5 to 12 Nm are offered.
These motors are up to 15% shorter and lighter than comparable servos. New insulation on
the windings and an overall sealant coating help protect the motor from the environment.
The
Series motors conform to international standards (IEC). The motor protection level is
IP65 (IP67 may be made available through special order).
A (32K – Beta) (64 K – Beta M) absolute encoder is standard with each
Series servo. An
optional 90 Vdc holding brake is also available with each model.
