SMSD-1.5 Stepper motor controllers SMSD-1.5 Programmable controllers SMSD-1.5 are designed to control small size stepper motors with output current under 1.6 A per motor's phase. The controller provides 3 main control modes - programmable, analog speed control and STEP/DIR position control. Digital I/O of the controller make it easy to use the controller together with other electronics of a system. The main parameters: • Max. current per phase: 0.16 - 1.6 Amp • Power supply: 10 - 30 VDC • Microstepping mode: 1, 1/2, 1/4, 1/8, 1/16 The control modes of SMSD-1. • Program mode - this mode is widely used for cycle and repetitive actions. The motion algorithm recorded from a PC or PLC to a nonvolatile memory of the controller and afterwards can be executed as per input signal or as per a command from a PC or PLC. • Direct cotrol mode - control of a stepper motor in real-time mode by commands, set from a computer or PLC. • Analog speed control - it is used for smooth speed regulation without communication interface connection. • Pulse position control STEP/DIR - the standard position control mode, motor speed is proportional to a STEP voltage signals frequency, displacement is proportional to a STEP signals quantity. Rotation direction depends on a voltage level at DIR input. Digital inputs/outputs: • Start/Stop • Reverse • Motion enable • Start zero positioning • "Home" position • Relay (programmable, output) • Inp1 and Inp2 -programmable inputs Tallinn Science Park Tehnopol, Phone: + 372 6559914, Maealuse st. 4, Tallinn 12618, Estonia e-mail: [email protected]
