EM705 Leadshine Digital 20-70VDC 0,35 – 7,0A

• Sensorless stall detection, eliminates costs of feedback device and cabling (>300RPM)
• Anti-resonance, provides optimum torque and nulls mid-range instabilities
• Supply voltage up to +70VDC (recommended not to exceed 63V because of “back EMF”)
• Output current programmable, from 0,1A to 7,0A (Peak)
• Automatic idle-current reduction (in standstill mode) to reduce motor heating; function switchable (reduction rate can be software configured)
• Motor self-test and parameters auto-setup technology, offers optimum responses with different motors
• Pulse input frequency up to 200kHz
• TTL compatible and optically isolated input
• Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance
• Microstep resolution programmable ´, from full-step to 102,400 steps/rev, setting via DIP switches or software
• Suitable for 2-phases and 4-phases motors
• Support PUL/DIR and CW/CCW modes
• Over-voltage, over-current, phase-error protections

Features:
The EM705 is a versatile fully digital stepping driver based on a DSP with advanced control algorithm. The EM705 is the next generation of digital stepping motor controls. It brings an unique level of system smoothness, providing optimum torque and nulls mid-range instabilities. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and makes it easy to use. The driven motors can run with much smaller noise, generate less heat, and move smoother than most other drivers on the market. Its unique features make the EM705 an ideal solution for applications that require low-speed smoothness.

Additionally, the EM705 has a build-in sensorless stall detection function to eliminate the cost of feedback devices and cabling.
Note: At present the EM705 only detects motor stall at running speeds >300RPM

Applications:
Suitable for a wide range of stepping motors of NEMA sizes 23, 24 and 34 (57×57 mm to 86×86 mm). It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Particularly well suited for applications where low noise Levels, less heat development, high Speed and high precision are desired.
