cycle power)
Aries 2.0
Units
Rotary motor: r = kgm2 * 1Ø-6
Linear motor: r = kg
Range
Rotary motor: Ø.ØØØ to 1ØØØØØØ.ØØØ : ±Ø.ØØ1
Linear motor: DMEPIT (electrical pitch) dependent
Default
Ø.ØØØ (DMTJ of Ø results in motor config. error)

Note: This command does not take effect until you cycle power to the drive,
or send the RESET command.
Auto-Setup: When using a Parker motor and the Aries Support Tool, this
command is automatically set for the selected motor.
If you did not use the Aries Support Tool, are using non-Parker motors, or
sent an RFS command to the drive, the parameter is set to zero (0)—you
must manually set this parameter to a non-zero number.
If the drive is powered up when this command is set to zero (for instance, if
RFS is executed), the drive reports a motor configuration error with E13, and
shuts down the drive (DRIVEØ).
For a list of auto-configured commands, see DMTR.
The DMTJ command sets the motor rotor inertia for rotary motors, or the
forcer mass for linear motors.
