LX-400 Motorola Brushless AC Servo Drive

The LX Series of brushless servo drives is the latest in analog amplifier design from Emerson EMC. The wide input voltage range and compact dimensions make it one of the most versatile amplifiers available. There are three amplifiers in the LX Series; the LX-400 (4.0 amps of continuous output current), the LX-700 (7.0 amps of continuous output current) and the LX-1100 (10.9 amps of continuous output current). All three amplifiers have the same physical dimensions. Each LX Amplifier is matched with the proven reliable DX Brushless Servo motors. When correctly matched, the LX Amplifier and DX Motor combinations offer continuous torque output ratings of from 10 to 100 lb.-in. The amplifiers incorporate pulse width modulated (PWM) design to provide efficient power conversion. Sine wave commutation of the motor results in smooth rotation across the full range of speed. All LX Amplifiers are designed with their own power supply, heat sink, shunt resistor and fan (when needed). This allows for simple installation and expansion. LX Amplifiers can be easily adjusted to operate with a variety of motors and controllers. A personality module attached to the amplifier retains all adjustments. If an amplifier needs to be replaced, the personality module can be removed and attached to a new amplifier, thus alleviating the re-adjustment process. Troubleshooting is aided through the use of status LEDs located on the front panel of the amplifiers. The LEDs continually keep the operator informed of the status of the amplifier at all times. In addition to the LED indications, fault conditions such as resolver fault and motor over temperature are announced as a contact signal output which can be monitored by a host controller. Input power voltage can range from 96 to 264 VAC 50/60 Hz without jumper or switch selection. A 230 VAC 50/60 Hz, 3Ø supply will deliver the maximum output power. Optimum performance from a servo system is accomplished by carefully matching the motor and amplifier. Emerson EMC’s DX Series of servo motors has been engineered to compliment the LX servo amplifier, providing unparalleled reliability and performance.
