1. Verify the SI unit for position has been set to mm.
This unit is used in the rest of the configuration for position and speed. This setting does not have any effect on the
configuration.
2. Verify the ratio of 10:1,024 has been set.
This ratio generates the number of pulses to reach the required position value.
a. Type value for Pulse per Revolution.
This value syncs up with the drive settings. The drive has been configured to rotate the motor by one revolution
when it receives 1,024 pulses.
b. Type value for Travel for Revolution.
This value syncs up with the mechanical system, such as ball screw, lead screw or linear belt. The mechanical
system moves 10 mm when the motor rotates one revolution.
