Motor

Syntax
<a_>DMTIND<r>
Aries 1.0
Units
r = mH
Range
Ø.Ø to 2ØØ.Ø : ±Ø.1
Default
Ø.Ø (DMTIND of Ø results in motor configuration
error)
Response
DMTIND <*>1Ø

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. Otherwise, the drive
reports the configuration errors E1–Motor Configuration Error and
E3–Maximum Inductance = Ø, and shuts down the drive.
For a list of automatically configured commands, see DMTR.
The DMTIND command specifies the maximum value of motor inductance.
This usually differs from the nominal nameplate value because actual
inductance is usually position dependent. If the maximum value of motor
inductance is not known, specify the nominal inductance as listed on the
motor’s nameplate.

The DMTINF command specifies the minimum motor inductance divided by
the maximum motor inductance. Setting DMTINF to 1.ØØ does not derate the
motor.
If the minimum value of the motor inductance is not known, use the nominal
inductance as listed on the motor’s nameplate (or set DMTINF1.ØØ)
