Appendix F

Enhanced Peak Performance

The default values that populate the AXIS_SERVO_DRIVE properties in the
Logix Designer application are calculated for each motor and drive, but assume
150% peak torque in those calculations. For the drive to command more current,
you must enter new values for some of those parameters, including the following:

TorqueLimitBipolar
TorqueLimitPositive
TorqueLimitNegative
MaximumAcceleration
MaximumDeceleration
AccelerationLimitBipolar
AccelerationLimitPositive
AccelerationLimitNegative

You can access these parameters offline in the Logix Designer application Axis
Properties tabs or online as sent to the drive in an SSV instruction.

To calculate the new values, you also need to determine these values:

Drive electrical data (Motion Analyzer solution page, under Drive tab)
Motor electrical data (Motion Analyzer solution page, under Motor tab)
TorqueScaling (the Logix Designer application, Axis Properties,

Output tab)

Figure 119 - Drive and Motor Data in Motion Analyzer Software

IMPORTANT

The default unit in Motion Analyzer software for drive and motor current is A
(0-pk). Because the example formula is in A (RMS), you must change the units
in the Drive and Motor tabs to A (RMS).

Pause your mouse over A (0-pk) and use the pull-down menu to change the
units to A (RMS). Refer to

Figure 119

for an example.
