DMC-1400 Series Command Reference MT ● 143
MT
FUNCTION: Motor Type
DESCRIPTION:
The MT command selects the type of the motor and the polarity of the drive signal. Motor
types include standard servo motors which require a voltage in the range of +/- 10 Volts,
and step motors which require pulse and direction signals. The polarity reversal inverts
the analog signals for servo motors, and inverts logic level of the pulse train, for step
motors.
