LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 4 Outline Drawing: SMAC LAC-15, the new 1-axis motion controller-drive is engineered with a Technosoft ISM4803 high-performance intelligent servo module, which is combining motion controller and drive functionalities into a single compact unit. The LAC-15 ISM module is a flexible, cost effective and compact solution, particularly adapted for distributed and coordinated control of brushless, DC, linear or step motors of powers up to 150W, with voltages up to 48V. Typical applications include distributed motor control with possibilities of...

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 6 Digital I/O Interface The LAC-15 provides total 4 general purpose inputs and 4 general purpose output. In addition, each axis has 3 dedicated inputs, Enable, Limit+ and Limit-, and 2 dedicated outputs, Ready, and Error. All inputs and outputs are compatible with TTL signal level and maximum current on outputs is 24 mA each.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 7 Analog Inputs The LAC-15 provides total 2 analog inputs with 10 bits resolution on A/D conversion; two analog inputs are REF and FDBK. The analog input range is +/- 10V that reference to GND. The input REF can be used as analog position, speed reference, and torque reference. The input FDBK can be used as tacho meter feedback.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 8 DC Brush and Brushless Motor connection CAUTIO': Before connecting the motor, be sure you have the right application programmed to E²ROM otherwise you can damage the motor and drive. At Power-on the TML application is automatically executed. See special instruction on how to disable this auto run feature.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 9 Differential Encoder Connection The LAC-15 provides 2 channels (A and B) of quadrature encoder interface with index signal input. +5VDC requires minimum of 50mA.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 10 Power Supply Connection The LAC-15 has wide range of Motor Power (Vmot) input between 12 to 48 V DC. The maximum supply Voltage is 50VDC.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 11 Serial RS232 Interface connection The LAC-15 provides a serial RS232 communication interface, one independent RS232 port. LAC-15 communicates with a host computer via RS232 port. The RS232 port has compliance with standard of TIA/EIA-232-C. The baud rate can be set between 9600 to 115,200 bits per second.

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 12 CA' Connection The LAC-15 provides one port of CAN communication interface.. LAC-15 CAN ports have compliance with standards CAN-Bus 2.0B; ISO11898-2. The speed of CAN bus can be up to 1M bits per second. Two and more LAC-15 can be linked in chain to form CAN network. Terminator resistor of 120 ohm is needed to install into the network at last node axis. In the multiple-axis CAN network, the aixsID must be set to each axis node. The first axis (axis-1) node should set the axisID as 255. The second axis (axis-2) can be assigned axisID...

LAC-15, 1Axis Controller/Amplifier User Manual Ver.A 13 Available Memory Area The LAC-15, the single axis controller driver, has two types of memory: a 1.5Kx16 SRAM (internal) memory and an 8Kx16 serial E²ROM (external) memory. The SRAM memory is mapped both in the program space (from 8200H to 87FFH) and in the data space (from A00H to FFFH). The data memory can be used for real-time data acquisition and to temporarily saved variables during a TML program execution. The program space can be used to download and execute TML programs. It is the user’s choice to decide how to split the 1.5-K...
