Motor Peak Current
Specifies the peak current allowed by the motor. The range is 1 to 100 ARMS. If the peak
current of the motor is greater than 30 ARMS, specify the peak as 30 ARMS. The drive will
limit the peak current to the drive's capacity.
Motor Continuous Current
Specifies the continuous current allowed by the motor. It is used to determine the current
foldback point and the amount of current allowed during foldback. The drive can also limit
the continuous current to the motor based on the drive capacity. This means that the
operational "continuous current" may be different than the value specified here. The range is
1 to 100 ARMS.
Motor Maximum Operating Speed
Specifies the maximum operating speed of the motor. It is used by the drive to set the default
motor overspeed trip point and to limit the Velocity Command. The Velocity Command is
limited to 9/8ths (112.5 percent) of the Motor Maximum Operating Speed. If the actual
velocity exceeds 150 percent of this value, the drive will fault on Overspeed. Typically this
parameter is determined by the encoder bandwidth and/or other mechanical or electrical
parameters of the motor. The maximum value is 11,000 RPM.
Step 6: Configuring the Drive
Once you have determined the motor parameters and entered them into the MOTOR.DDF
file, you can configured the drive to the user defined motor using PowerTools software. Once
PowerTools is started it will read the MOTOR.DDF file and you will be able to select the non-
Control Techniques motor.
Selecting a User Defined Motor
Use the following procedure to select the user defined motor with PowerTools:
1. Start PowerTools and either open an existing file or start a new file offline.
Note
PowerTools will not allow you to select a "Motor Type" or "Drive Type" while online
with a drive.
2. From the "Motor Type" list box on the EZ Setup tab (or from the Motor tab if you are in
Detailed Setup view) select your motor from the list of motors.
When you select a new motor, PowerTools will display the Motor Parameters dialog box.
In most cases you will want to select the default option which sets the Full Scale Velocity
parameter to the value you entered into the MOTOR.DDF file.
