    Bus power sharing capability Ø Description 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.
  • Page 8 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.

  • Page 11 The Limit switch inputs and Emulates encoder outputs are standard on the LX, however these features can be deleted when purchasing quantities of drives to further reduce costs. See your Emerson Sales Representative for further details. Basic Function and Operation The amplifier is designed to operate in either a velocity command or current (torque) mode with an analog ±10 volt command.
  • Page 12 velocity of the motor to the velocity commanded by the drive and adjusting the current command as needed to maintain the commanded velocity. Velocity Loop In the velocity loop circuit the error signal is processed by a P.I.D. (Proportional, Integral and Derivative).
  • Page 13 Diagnostics and Fault Handling A number of diagnostic and fault detection circuits are incorporated in the LX amplifier to protect the drive. Some faults like over voltage, under voltage and amplifier or motor over temperature reset when the fault is cleared. Other faults such as short- circuit at the motor output terminals and/or resolver fault need to be reset by cycling power.
  • Page 14 Power Section On the main board, the high current and the signal sections are optically isolated. Looking at the block diagram (Figure 1-3) the main functions of the drive can be identified. The power stage DC bus is supplied by the AC line input to the drive and the internal diode bridge rectifier followed by a set of filtering capacitors.

    Installation The following installation requirements, methods and procedures are provided to assure reliable and trouble free installation of your Emerson MC LX Drive. The methods and procedures are outlined on the following pages and include site requirements, safety considerations, power and fusing requirements, wire and transformer sizing, noise suppression, and I/O wiring.
  • Page 17 Amplifier Mounting The LX drives must be mounted in a vertical orientation to insure the best air flow between the cooling fins of the heatsink. Mounting above other drives or any heat producing equipment may result in overheating. The mounting brackets are attached to the LX drive heatsink by self tapping screws and thus are well grounded to the amplifier chassis.
  • Page 18 Motor Installation 2.5.1 Motor Mounting To provide good mechanical alignment, the mounting surface of the motor face plate is held perpendicular to the motor shaft to within 0.005 inches. Projecting above the plane of the mounting surface is a close tolerance circular pilot boss. Matching the pilot boss with a pilot hole in the mounting structure facilitates interchanging the motor and minimizes the need for mechanical adjustments.

  • Page 20 INSTALLATION -- ELECTRICAL Wiring Wiring of any industrial equipment should be done with some consideration for future troubleshooting and repair. It is a good idea that wiring be either color coded and/or tagged with industrial wire tabs. 3.1.1 Interlocking The user is responsible for emergency interlock switches. Any master interlock should be wired to shut down AC power to all parts of the system.
  • Page 21 Magnetic Coil Noise In the case of DC coils, a diode is installed across the coil in a direction that will cause the voltage transient to be dissipated through the diode. Figure 3.1 DC Coil Suppression In the case of AC coils, a capacitor and resistor are installed across the coil to suppress the unwanted transients.

    Table 3-A – Power Wiring and Fusing Model MINIMUM WIRE SIZE AWG FUSE RATING AMPS LX-400 LX-700 LX-1100 Recommended fuse type is a LOW PEAK delayed action type fuse such as Bus brand type LPN fuse. A standard rated delayed action or dual element fuse such as Bus brand FRN may be used in lieu of the Low peak type fuse when availability dictates but the level of drive protection afforded by the LPN fuse is better.
  • Page 25 The following formula can be used for transformer sizing. For each secondary winding, the power in VA is: Ps - (Paz * 1.5) * 1.73 / √ (n+2) where: Paz = (Vm1*Cm1 + Vm2* Cm2 + .... + Vmn*Cmn) Vm = motor max speed in rad/sec (RPM/9.55) Cm = nominal motor torque in Nm(lb-in/8.85) 1.73/√(n+2) = corrective factor when using more than one drive supplied in parallel with n= number of drives.

  • Page 44 START UP / CALIBRATION This chapter will cover the steps necessary to correctly adjust an LX drive. In some cases the most accurate adjustment requires some test equipment such as an oscilloscope, tachometer or a voltmeter. The type of test equipment required is dependent on the type of controller that is employed and the level of calibration accuracy required for the application.

  • Page 46 5.1.2. Cal. Speed Adjustment This adjusts the command voltage input levels so they match the controllers output levels. In other words, if the controller puts out 8.5 volts for a 3000 rpm command, the drive must be adjusted to deliver 3000 rpm with an 8.5 volt command. The adjustment range is from 75% to 140% of the DIP switch (SW1/1 setting) 3000 / 6000 rpm.
  • Page 47 Apply 25% of the max command and verify the speed per the above. Continue increasing the command signal level in 25% increments and verifying / adjusting Cal Speed until 100% speed command is achieved . Follow the above procedure in the opposite motor direction to check for velocity offset.
  • Page 48 Start with the Gain adjustment and the Response pot fully CCW. The trace will probably look like Figure 5.1. Turn the Gain CW until most of the instability is gone and the Tach trace looks like Figure 5.2. Now turn the Response CW until the trace looks like Figure 5.3.
  • Page 49 5.1.4 Dynamic Calibration without Oscilloscope An acceptable calibration can normally be obtained by setting the calibration potentiometers in the following fashion. CAUTION! THE FOLLOWING ADJUSTMENT PROCESS WILL CAUSE HIGH FREQUENCY MOTOR INSTABILITY AND OSCILLATION FOR A SHORT PERIOD OF TIME. VERIFY THAT THE LOAD WON’T BE DAMAGED BY THIS MOTION.

  • Page 50: Special Applications

    SPECIAL APPLICATIONS External Shunt Resistor LX drives leave the factory with the internal shunt resistor enabled through an externally wired jumper between terminal pins 27 and 28. If the power rating of the internal shunt resistor is insufficient for heavy cycles an external shunt resistor with greater power capacity should be added.
  • Page 51 Current Command Mode LX drives can be operated in torque mode or current command mode using terminal pin 2 (CUR CMD) as an input for the current command signal. The command signal range is ±10V. Terminal pin 2 is a bi-directional terminal with an input impedance of 20 kΩ . Output impedance of the device driving the CUR CMD input must be 50W or less (standard operating amp output).
