Stepping Motor Controllers SMC and iSMC Series Stepping Motor Controllers Description These controllers are designed for use with stepping motors. Motors sold separately. iSMC™ shown with a stepping motor, sold separately     SMC-3.5 includes a hand-held remote control 1-2 Axis iSMC™ New! The new iSMC from Thermionics is a cost-effective motor control solution for up to two motorized axes. It is ideal for applications such as operating a PLD target gearbox on a dual-axis rotary feedthrough, where one axis is used for clocking the targets and the other for continuous rotation of the target. [ read more... ] 1-6 Axis SMC The SMC 3.5 stepping motor controller will drive up to 6 motors with output currents up to 3.5 amps in a single 7 inch high rack mount chassis. It can be operated as a stand alone unit with the standard hand held terminal or with a computer using the RS-232 communications port at rates of up to 57,600 baud.

It is ideal for applications such as operating a PLD target gearbox on a dual-axis rotary feedthrough, where one axis is used for clocking the targets and the other for continuous rotation of the target. The control unit includes the power supply, communications interface and access to the digital and analog inputs of the Intelligent Motion Systems MDI series stepping motors. A control computer with an available COM port is required to run the iSMC. Specifications 1 or 2 axes of stepping motor control Programmable microstepping rates up to 51,200 steps per revolution Programmable holding and run currents NV RAM for program and variable storage Drive rates to over 3 million pulses per second Four digital inputs for each motor One analog input for each motor Requires computer (RS-232) for control RS-232 interface with baud rates up to 115kbps 115/230 VAC, 50/60 Hz operation Includes all necessary cables (15') 5.5" H x 5" W x 8.5" D For use with TLI motors only SMC One- to Six-axis Stepping Motor Controller SMC-3.5 includes a hand-held remote control Thermionics provides a powerful yet economical solution for demanding motion control requirements covering a wide range of applications. The SMC 3.5 stepping motor controller will drive up to 6 motors with output currents up to 3.5 amps in a single 7 inch high rack mount chassis. It can be operated as a stand alone unit with the standard hand held terminal or with a computer using the RS-232 communications port at rates of up to 57,600 baud. With the SMC controller you can be up and running in minutes. Features such as backlash compensation, electronic gearing, closed loop positioning, and homing routines are built in to save you valuable programming time. Outside events can be synchronized using the 12 digital inputs and 14 outputs. Other SMC features include hardware and software emergency shut down functions, hardware and programmable soft end limits and step-to-coordinate conversions. All configurable system and axis parameters can be saved to non-volatile EEPROM. Hand Held Terminal Axis information and control is at your fingertips with the standard hand held terminal. The position and status of each axis is continuously updated on the easy to read 8 line by 24 character screen. A comprehensive set of menus provides access to all of the SMC settings so the controller can be quickly and easily configured. Features 32 bit axis position registers provide over ±2 billion counts Velocity settings to 3 million pulses per second Position display in steps, inches, millimeters, centimeters, degrees, radians, or revolutions Relative, absolute, continuous, and jogging motions Closed loop operation (with optional incremental encoders) 4 hardware homing routines (with optional hardware position input) Electronic gearing provides multi-axis synchronized motion Programmable backlash correction Hardware and software emergency stop 4 hardware end limits per axis Programmable software end limits EEPROM stores 10 system parameters and 30 axis parameters Specifications 1 to 6 axes Switch selectable output currents from .5 to 3.5 amperes Motor resolutions: 200 and 400, microstepping available Full short circuit protection Hardware end limit input 12 digital input lines 14 digital output lines RS-232 interface for host computer control 7" x 19" x 20" rack mount chassis 120/240 VAC 50/60 Hz AC Cable (10') Motor cabling (12') End limit switch cables (25') Ordering Information iSMC Two-axis Stepping Motor Controller Number of Axes Model No. Price 1 iSMC-1 $1,650 2 iSMC-2 $1,850 SMC One- to Six-axis Stepping Motor Controller Number of Axes Model No. Price 1 SMC-3.5-1 $3,350 2 SMC-3.5-2 $4,000 3 SMC-3.5-3 $4,850 4 SMC-3.5-4 $5,500 5 SMC-3.5-5 $6,150 6 SMC-3.5-6 $6,800      Options Option: Zero Position Input Model Number: /ZP Price: add $350 Accepts input from zero position indicator for precise home positioning Can be used with Z channel of the quadrature encoder for unique home position The following two options are available for SMC 3.5 models only: Option: 7 Amp Driver Model Number: /7 Price: add $550 per axis Replaces the 3.5 amp driver for higher torque requirements Option: Encoder Input Model Number: /E Price: add $750 1-6 axis input of quadrature encoders Accurately updates the internal position register for each axis Provides closed loop operation for accurate positioning
