esp_set_motor_type() defines the motor type or technology used to control the speci-
fied axis.
esp_get_motor_type() reports the motor type or technology used to control the speci-
fied axis.
This is necessary because the ESP6000 needs to apply different control algorithms for
different motor types. For example, DC servos are controlled via digital-to-analog
converter (DAC) whereas stepper motors are positioned via digital rate multiplier.
It will not be possible to control an axis if its motor type is undefined or equal to
zero (0).
Motor type is automatically set for ESP-compatible stages.
ESPOK, ESPERROR
Verify motor/stage is a defined motor type.
