esp_set_gear_constant() API call is used to set the UniDrive6000 motor amplifier
gear constant for the specified servo axis and should be used in conjunction with
esp_set_tach_constant(). The gear constant is defined as the number of revolutions the
motor has to make for the motion device to move one displacement unit. To take immedi-
ate effect this command should be followed with the esp_update_unidrive() command.
Poor servo performance can occur if gear constant is inappropriately set.
Please refer to stage specifications before setting value.
