Drive: Pulses per revolution
Servo and stepper motor drives have either switches or software tools to setup the drives Pulses Per
Revolution (PPR) settings. These settings define how many pulses the drive will take to turn the motor shaft
one complete revolution.
INFORMATION: Please refer to your motor drives documentation on how to setup PPR.
Maximum Feed Rate
Each machine axis have limitation of maximum allowable speed depending on the hardware and safety
limitations. The maximum feed rate value is used to check and make sure that the system does not exceed
this value during operation. This value might be different for each axis depending on the design of that axis.
Acceleration
Depending on the moving mass and motor torque the acceleration value can be set for each axis.
Minimum & Maximum Travel
These values define the travel as well as minimum and maximum values of the axis. In most setups this
values is between 0.00 and some positive number, but in some cases such as Z axis of a milling machine
this value can be negative as the axis homes towards the top which is 0.00 but the actual machining
happens in the negative direction that is towards the machine bed.
NOTE: The minimum and maximum travel also sets the soft limit of the axis and its very important
to set this value with the exact travel of the axis.
INFORMATION: If minimum, maximum or homing position (in homing settings window) values are
