Servo Parameters
Chapter 7
7-91
Function
This parameter is not available for digital servos connected to the 4-axis
8520 digital servo card or to the 9/230 8520 digital CNC. It is used for
9/260 or 9/290 systems that use the 3-axis 8520 digital servo cards and
servo systems designed to connect to any 1394 digital system, including
the 9/440 CNC.
Enter the maximum motor speed (in RPM) that your motor/drive/load
combination allows.
The motor speed entered here should be approximately 10% above what
would be required for the axis to achieve its maximum feedrate.
Standard motor rated speeds and maximum speeds are shown in the motor
tables of your integration and maintenance manual. The correct value for
the selected motor should be entered here.
If a nonstandard motor is to be used, motor maximum speeds can be
obtained from the motor specification literature.

Notes
This parameter must be set independently for each servo.
Digital Spindle users must set this parameter to determine the maximum
gear one motor speed in addition to configuring the spindle group
parameter “Maximum Spindle Speed -- Gear 1”. Also keep in mind the
maximum motor speed for a digital spindle using 1326 resolver based
systems set to use the higher available feedback resolution (32768 counts
per rev) is limited to 3000 RPM. If higher motor speeds are required for
your resolver based digital spindle use the lower (8192 counts per rev)
feedback setting for both velocity and position feedback.
