DMTINF Motor Inductance Factor
Type Motor Product Rev
Syntax <a_>DMTINF<r> Aries 1.0
Units r = units
Range Ø.ØØ to 1.ØØ
Default 1
Response DMTINF <*>1.ØØ
See Also CONFIG, DMTIND, DMTR
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 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)
DMTIP Peak Current
Type Motor Product Rev
Syntax <a_>DMTIP<r> Aries 1.0
Units r = Amps-RMS
Range Ø.ØØ to 4ØØ.ØØ : ±Ø.Ø1
Default Ø.ØØ (DMTIP of Ø results in motor configuration
warning)
Response DMTIP: <*>7.5Ø
See Also DMTIC, DMTICD, DMTLIM, DMTR, TDIMAX
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
E9–Peak Current = Ø.
For a list of automatically configured commands, see DMTR.
The DMTIP command sets a limit that the commanded current cannot
exceed. This is typically set to three times the motor’s continuous current
rating (DMTIC) or less.
If DMTIP is set higher than the full-scale value calculated by DMTLIM
(torque/force limit) the new DMTIP value will be ignored.
