Feature: 1. DRIVER AND WIRING: Composed of driver and wiring, and integrates the functions of 2 general 2 phase stepper drivers in a driver housing, saving space and wiring. 2. CONTROL 2 MOTORS: Can input 2 different pulses, direction and enable control signals at the same time to control 2 different motors without interference with each other. 3. STANDARD WIRING: The motor wiring uses 2.54MM standard sockets, the flat cable uses a single PH head 24AWG wire, the length is 300MM, and the signal wiring uses 26AWG wire. 4. APPLICABLE MOTOR: The subdivision number of each motor is a multiple of 2, which can be adapted to 57, 42, 39, 28, 24, etc. 2 phase stepper motors below 2A. 5. WIDE APPLICATIONS: Widely used in automation equipment, such as 3D printers, engraving machines, laser machines, packaging equipment, automated production lines, etc. Specification: Item Type: Stepper Motor Driver Model: SMD-1524-M32S-TV10 Specification: 4 phase 5 wire unipolar type Speed Response Rate: 100KHz Operating Temperature: 0-50℃ Operating Humidity: 40-90%RH Input Voltage: DC10V-26V Input Current: > 5A Allowable Input Power Ripple: ≤ 50MV 1. Wiring Method: GND: DC power supply earth wire +V: DC power supply positive pole, range 10V-26V, recommended value +24VDC A+, A-: A phase coil of the motor B+, B-: B phase coil of the motor VM: Motor coil power supply pin, which is connected to V+ pin in the positive direction 2. Control Signal Interface Function: PUL+(+5V) PUL-(PUL): Pulse Control Signal: The rising edge of the pulse is valid; PUL is 4~5V at high level, and 0~0.5V at low level. In order to reliably respond to pulse signals, the pulse width should be greater than 1.2μs. If +12V or +24V is used, a series resistance is required; 12V series 1K ohm 0.25W resistance, 24V series 2R ohm 0.5% resistance. DIR+(+5V) DIR-(DIR): Direction Signal: High low level signal. To ensure reliable commutation of the motor, the direction signal should be established at least 5μs before the pulse signal. The initial running direction of the motor is related to the wiring of the motor, interchange any phase winding (such as A+, A- exchange) can change the initial running direction of the motor, DIR- high level 4~5V, low level 0~0.5V; 12V string 1K ohm 0.25W resistor, 24V string 2R ohm 0.5% resistor. ENA+(+5V) ENA-(ENA): Enable Signal: This input signal is used to enable or disable. When ENA+ is connected to +5V and ENA- is connected to low level (or the internal optocoupler is turned on), the driver will cut off the current of each phase of the motor to make the motor in a free state, and the step pulse will not be responded at this time. When this function is not needed, the enable signal terminal can be left floating; if +12V or +24v is used, a series resistance is required, 12V series 1KΩ 0.25W resistance, 24V series 2R Ω 0.5% resistance. .
