Parker Hannifin
Chapter 6 Command Reference 113
When you select a specific Parker motor using the Aries Support Tool, the
DMTR setting and various motor parameters (see Servo Motor Data
Parameters below) are automatically configured for the associated motor.
Using the Aries Support Tool, you can save the parameters in a configuration
file.
For the DMTR and all the motor parameter commands to take effect after
downloading the configuration file to the Aries drive, you must cycle drive
power or send the RESET command.
Note: For a non-Parker motor, the default setting is blank (empty). You must
set all relevant motor parameters manually.
Avoid using the DMTR command to change the motor name, because the
new DMTR value may not represent the actual motor parameters that are
currently loaded in the drive.

Although these command values are auto-configured when you select a
Parker motor (using the Aries Support Tool), you may individually set the
command values with the respective configuration command.
Motor Configuration Error
Many of the above motor parameters, if not configured (i.e. a command
remains at its factory default value, or an RFS command is executed) will
report a motor configuration warning or error when powering up the Aries
drive—EØ–Motor Configuration Warning or E1–Motor
Configuration Error (an error also disables the drive—DRIVEØ). To
resolve the error or warning condition, you must select a Parker motor using
the Aries Support Tool (or configure each motor parameter command with a
value other than zero using a terminal emulator), download the resulting
configuration information, and then send the RESET command or cycle
power.
