Chapter 9 Axis Axis software positive limit Setting Users can set the positive software limit value of the axis, which is only applied to the linear axis. Axis software negative limit Setting Users can set the negative software limit value of the axis, which is only applied to the linear axis. Rotary Maximum Position Setting Users can set the maximum position of the rotary axis which moves toward the positive direction. The position value will be calculated again from the minimum value after the axis reaches the limit value. Users can set the minimum position of the rotary axis which moves toward the negative direction.
The position Rotary Minimum Position Setting value will be calculated again from the maximum value after the axis reaches the limit value. Gear Ratio Numerator Users can set the numerator value of the electronic gear ratio. Gear Ratio Denominator Users can set the denominator value of the electronic gear ratio. Homing Acceleration The acceleration speed while homing is performed. Homing Velocity The parameter is the speed while the homing is performed Homing Closed Velocity While the homing is performed, the motor moves at the homing velocity at first. Then the motor starts to decelerate to this velocity and moves at this velocity when the trigger is close to the home signal.
Permitted Deviation The permitted deviation between the actual position and the command position The axis parameter setting window provides the following tool bar for editing the axis parameter table. Single Axis Start Immediately Users can select Disable or Enable. When single axis is enabled, it will enable motion immediately and not be affected by the CPU cycle time. Please refer to AHxxEMC Series PLC manuals for more information. MC_CamIn Master Direction Users can select Positive Direction or No Direction. Under Positive Direction, the main axis moves backwards and this will halt the slave; Under No Direction, the slave is not affected by the main axis moving forward or backwards.
