SDM-20242 4-axis Full/Half Stepper Drives
The SDM-20242 contains four drives for operating two-phase bipolar step motors.The SDM-20242 requires a single 12–30 DC Volt input.The SDM is user-configurable for 1.4 A, 1.0 A, 0.75 A, or 0.5 A per phase and full, half, 1/4 or 1/16 step. Adequate airflow across the board is recommended. The SDM uses 9-pin D-sub connectors for encoder and limit connections on each axis and a 25-pin D-sub connector for I/O connections. 4.25" ´ 3.70".
SDM-206x0 2- and 4-axis Microstep Drives
The SDM-20640 contains four microstepping drives for operating twophase bipolar stepper motors.The drives produce 64 microsteps per full step or 256 steps per full cycle which results in 12,800 steps/rev for a standard 200-step motor.The maximum step rate generated by the controller is 3,000,000 microsteps/second. Correct motor sizing calculations are critical to achieve stepper performance at speed. Please contact GMP for assistance. The SDM-20640 drives motors operating at up to 3 Amps at 12 VDC to 60 VDC (available voltage at the motor is 10% less).There are four software- selectable current settings: 0.5 A, 1 A, 2 A and 3 A.Plus, a selectable low-current mode reduces the current by 75% when the motor is not in motion.No external heatsink is required. A two-axis model, the SDM-20620 is also available.
