Position Smoothing - Mitsubishi Electric EZMOTION MR-E Super MR-E-10A-QW003 Instruction Manual

5. PARAMETERS

5.2.5 Position smoothing

By setting the position command acceleration/deceleration time constant (parameter No.7), you can run the
servo motor smoothly in response to a sudden position command.
The following diagrams show the operation patterns of the servo motor in response to a position command
when you have set the position command acceleration/deceleration time constant.
Choose the primary delay or linear acceleration/deceleration in parameter No.55 according to the machine
used.
