MT (Motor Type)
[Configuration]
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 servomotors, and inverts
logic level of the pulse train, for step motors.
Warning: This command interacts with the CE command, which reverses the incoming encoder signals. Use caution
(motor off, machine estopped) when changing the MT or CE commands. If the two commands are not in
agreement with each other, the motor will run away at full speed when enabled.
ARGUMENTS: MT n,n,n,n
or
MTA=n

n = 2
Specifies Step motor with active low step pulses
n = -2.5 Specifies Step motor with reversed direction and active high step pulses
n = 2.5
Specifies Step motor with reversed direction and active low step pulses
