Custom Limits Attributes
Use this dialog box to monitor and edit the advanced limit-related attributes, or parameters.
When the Logix Designer application is online, the parameters on this tab transition to a read-only state. When a parameter transitions to a read-only state, any pending changes to parameter values are lost, and the parameter reverts to the most recently saved parameter value.
When multiple workstations connect to the same controller using the Logix Designer application and invoke the Axis Wizard or Axis Properties dialog, the firmware allows only the first workstation to make any changes to axis attributes. The second workstation switches to a Read-Only mode, indicated in the title bar, so that you may view the changes from that workstation, but not edit them.
Parameters
The following attribute, or parameter, values can be monitored and edited in this dialog box:
Attribute/Parameter | Description |
VelocityLimitBipolar | This attribute sets the velocity limit symmetrically in both directions. If the command velocity exceeds this value, VelocityLimitStatusBit of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^12. |
AccelerationLimitBipolar | This attribute sets the acceleration and deceleration limits for the drive. If the command acceleration exceeds this value, AccelLimitStatusBit of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^15. |
VelocityLimitPositive | This attribute displays the maximum allowable velocity in the positive direction. If the velocity limit is exceeded, bit 5 ("Velocity Command Above Velocity Limit") VelocityLimitStatusBit of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^12. |
VelocityLimitNegative | This attribute displays the maximum allowable velocity in the negative direction. If the velocity limit is exceeded, bit 5 ("Velocity Command Above Velocity Limit") VelocityLimitStatusBit of the DriveStatus attribute is set. This attribute has a value range of -2.14748x10^12 to 0. |
VelocityThreshold | This attribute displays the velocity threshold limit. If the motor velocity is less than this limit, VelocityThresholdStatus of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^12. |
VelocityWindow | This attribute displays the limits of the velocity window. If the motor’s actual velocity differs from the command velocity by an amount less than this limit, VelocityLockStatus of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^12. |
VelocityStandstillWindow | This attribute displays the velocity limit for the standstill window. If the motor velocity is less than this limit, VelocityStandStillStatus of the DriveStatus bit is set. This attribute has a value range of 0 to 2.14748x10^12. |
AccelerationLimitPositive | This attribute limits the maximum acceleration ability of the drive to the programmed value. If the command acceleration exceeds this value, AccelLimitStatusBit of the DriveStatus attribute is set. This attribute has a value range of 0 to 2.14748x10^15. |
AccelerationLimitNegative | This attribute limits the maximum acceleration ability of the drive to the programmed value. If the command acceleration exceeds this value, the AccelLimitStatus bit of the DriveStatus attribute is set. This attribute has a value range of -2.14748x10^15 to 0. |
TorqueLimitPositive | This attribute displays the maximum torque in the positive direction. If the torque limit is exceeded, the TorqueLimitStatus bit of the DriveStatus attribute is set. This attribute has a value range of 0 to 1000. |
TorqueLimitNegative | This attribute displays the maximum torque in the negative direction. If the torque limit is exceeded the TorqueLimitStatus bit of the DriveStatus attribute is set. This attribute has a value range of -1000 to 0. |
TorqueThreshold | This attribute displays the torque threshold. If this limit is exceeded, the TorqueThreshold bit of the DriveStatus attribute is set. This attribute has a value range of 0 to 1000. |
