Parker Hannifin
Chapter 6 Command Reference 109
If the DMTIP value exceeds the drive’s maximum output current (TDIMAX),
the DMTIP value will be ignored and the maximum allowable value will be
used (see Table 45). The drive reports EØ–Motor Configuration
Warning and E12–Peak Current Too High.

Syntax <a_><!>DMTJ<r> (does not take effect until RESET or
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)
Response DMTJ: *DMTJ2ØØ.6ØØ

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.
