NEMA17 7.0 Kgcm Stepper Motor for high torque applications. Ideal Motor for ATM machines, 3D printers, Peristaltic pumps and job positioning and rotating applications. Standard NEMA 17 frame size. 7.0 Kgcm bipolar configuration motor.
The DM542 is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM542 can drive a stepper motor at much lower noise, lower heating, and smoother movement.
Its unique features make DM542 an ideal choice for high requirement applications. The PULSE/STEP, DIRECTION inputs are optically isolated. Both inputs work with 2.5V, 3.3V or 5V logic drive signals. The input drive current is 5mA at 2.5V so almost all logic family (74LS, 74HC, etc.) can be used to drive these inputs. Each input provides individual anode and cathode connections to the opto-isolator allowing for multiple input drive interfaces.
