em253 bit module, the perfect coordination of speed and accuracy using a simple, precise control of the control em 253 stepper motor from the micro to the intelligent servo drive. Running fast and unfettered integration of the interface can generate 200khz pulse of the pulse signal, specify a location, speed and direction. Integrated position switch input from the central processing unit can be completed independently position control tasks. Adaptive pulse or rs422 5v DC input. Low shock can select "jerk"/s-curve function can be reduced at the start, stop and change speed and shock generated when the rear seat. Control of flexible and powerful program can be configured by the user and select the 25 profile, each profile can have up to four speed change. Absolute, relative and can be manually positioned ; distance and location of the units are set to mm, inches, degrees or number of pulses. You can choose four different reference point search mode. Simple software configuration, graphical, integrated step 7-micro/win, v 3.2 (and above) of the wizard has the following features: parametric (basic parameter settings) to create a profile to determine the positioning of the reference point search mode integrated micro/win in the control panel, easy-em253-line parameters support changes and parametric functions.
