Index Card Curve Info
Cycles/min Master
This specifies the number of cycles of the master
per minute. In most cases, this will be the
(maximum) number of products that are processed
per minute.
Maximum Actual Velocity
Max actual Velocity indicates the maximum velocity of the slave required by this curve profile in user units
per master unit (UU/MU). This is also shown as a percentage of the Slave Velocity Limit. If the velocity
exceeds the limit, then it is shown in red.
You can graphically display the velocity in the curve profile diagram by enabling →
curve of the slave will be shown in blue and the axis will be displayed on the right side of the chart (as long
as acceleration and/or jerk are not also being displayed). Note that it may be necessary to press the Reset
Zoom toolbar button for the velocity curve to be displayed with the proper scale within the existing chart
boundaries.
Slave Velocity Limit
Slave Velocity Limit is the maximum velocity of which the slave is capable, given the current value of
Cycle/min Master and the maximum speed rating of the slave motor. As Cycle/min Master increases, Slave
Velocity Limit will decrease so that the actual velocity of the slave does not exceed the maximum speed
rating of the slave motor. If the velocity required by this curve (Max actual Velocity) exceeds this limit, then
the slave will not be able to follow the master.
If → Vel. Limit is enabled, then the velocity limit will be displayed as horizontal dark-blue lines in the
curve profile diagram. Note that both positive and negative velocity limits are displayed.
Maximum Actual Acceleration
Max actual Accel. indicates the maximum acceleration of the slave required by this curve profile in user
units per master unit squared (UU/MU²). This is also shown as a percentage of the Slave Accel. Limit. If the
acceleration exceeds the limit, then it is shown in red.
You can graphically display the acceleration in the curve profile diagram, by enabling →
curve of the slave will be shown in magenta and the axis will be displayed on the right side of the chart (as
long as velocity and/or jerk are not also being displayed). Note that it may be necessary to press the
Reset Zoom toolbar button for the acceleration curve to be displayed with the proper scale within the
existing chart boundaries.
Slave Acceleration Limit
Slave Accel. Limit is the maximum acceleration of which the slave is capable, given the current value of
Cycle/min Master and the maximum acceleration rating of the slave motor. As Cycle/min Master increases,
Slave Accel. Limit will decrease so that the actual acceleration of the slave does not exceed the maximum
acceleration rating of the slave motor. If the acceleration required by this curve (Max actual Accel.) exceeds
this limit, then the slave will not be able to follow the master.
If → Accel. Limit is enabled, then the acceleration limit will be displayed as horizontal dark-magenta lines
in the curve profile diagram. Note that both positive and negative acceleration limits are displayed.
