Positioning Control Components of Positioning Control and Their Roles 3

3.1.3 Setting the acceleration/deceleration time
• When the start command is given, acceleration, operation at constant speed and
deceleration are performed for positioning. Set the acceleration time and the deceleration
time in the parameters.
• This operation pattern is effective during return to the zero point, positioning and jog
operation.
3.1.4 Backlash correction function
• The positioning controller can output excessive pulses, only when the movement direction
is inverted so that the backlash of the mechanical system is corrected.
