STEPPER MOTOR DRIVER - AMIS-30522
Description
The AMIS-30522 is a micro-stepping stepper motor driver for bipolar stepper motors. The IC can be interfaced via I/O pins and the SPI bus to an external microcontroller.
The AMIS-30522
contains a current translation table and takes the next micro-step on every rising (or falling) edge of the signal on the NXT input pin. The DIR register or input pin defines the direction of rotation. The IC provides a speed and load angle output signal. This in turn enables running on the external microcontroller stall detection algorithms and control loops based on load angle, and to adjust torque and speed accordingly. AMIS-30522 uses a proprietary PWM algorithm for reliable current control. Additionally, the AMIS-30522 has an on-chip voltage regulator, reset output and watchdog reset.
The AMIS-30522 is implemented in AMIS I2T100 technology, combining both high-voltage analog circuitry and digital functionality on the same IC. The IC complies with automotive requirements.
AMIS-30522 is available in SOIC-EP-24 (exposed pad) as well as the compact, thermally enhanced 7x7 NQFP-32.

SPORT232-ST STEPPER MOTOR CONTROL BOARD
The SPORT232-ST Stepper Motor Control Board Series is designed for multi stepper motor control through a serial port from a PC, PLC, or embedded system. The boards come with a chopper driver for
one axis and can be connected in daisy chain for 16 simultaneous axes control. The board also provides 8 analog and digital inputs. The SPORT232-ST can be connected in daisy chain, programming a valid address from 0 to 15, with feature until 16 can be controlled.
Four channels with signal conditioning included into the board. The input voltage range are: 0-2.5V, 0-5V, and 0-10V, jumper selectable.
Depending on different models the SPORT232-STI series can be programmed in stand alone mode.
External Trigger, External Event, Home, Abort, Limit Switch, Shaft Encoder signals are provided via Motor Control Connector.
Description:
The SPORT232-ST is a Data Acquisition Control and One Axis Stepping Motor Ready Board. With eight analog independent channels for different voltage range, the SPORT232-SP is ready to connect to sensors such as thermocouples, pH probes, photo cells, strain gauges, and piezoelectric sensors for data acquisition applications. In addition, to the Data Acquisition capabilities 4 channels feature low off-set signal conditioning which allows connection to almost any analog device without having to undergo the time and expense of developing an amplifier for the external device.
The SPORT232-ST also offers 8 digitals I/O that are TTL compatible. Each line can source/sink up to 5mA.
The SPORT232-ST has been implemented with one industrial PC driven stepper motor axis controlled, on board by the RMV856-ETX Controller. Acceleration and deceleration modes are supported. A velocity-profiling feature is also available for complex motion parameters. Inputs for external control such as abort, limit and home allow easy interfacing with mechanical system. Analog and digital inputs give the user a variety of options for sensor reading and actuator control. Networking through the RS232 port gives the system the ability to control up to 16 stepper motors, by daisy-chaining up to 4 boards in a multi-drop configuration. A 32-bit DLL allows easy interfacing to Windows, Linux, programming languages, moreover a demo software example is also included.
Main Features:
--------------------------------------------------------------------------------
Motor Control Full step (monophasic & biphasic), half step, and profiling moves. The SPORT232-ST can work with bipolar and unipolar stepper motors.
Motor Current The SPORT232 has been developed with a chopper driver in which can drive the motor current from 50 mA to 2000 mA. The power supply for the motor can be up to 45V. The motor winding current can be set up via software.
Stepping Modes Linear acceleration and deceleration modes are supported. Smooth motion and higher torque are achievable at high speed trough the use of a special half step torque compensation technique.
Profiling movements are supported and it can be selected via software. A 128 bytes of internal FIFO allows to store different motion segments when profiling move is selected.
Digital Inputs
8 TTL compatible I/O lines are provided. Each line can be configured as input/output independently via software.
Motor Control Signals
The motor control signals are: Abort, Home, Limit Switch, External Trigger, External Events, Shaft Encoder channel A and B.
Analog Inputs
The SPORT232-ST board supports 8 analog inputs. The resolution of the digital converter is 12 bits. Four channel has been developed with signal conditional ready, in which the input voltage range are: 0 to 2.5 Volts; 0 to 5 Volts , and 0 to 2.5 Volts.
The SPORT232-STI model has a 2.5 V. Voltage reference available, and can drive until 10 mA. This feature is very important when external signal conditioning are used.
