Naming & Configuring Your Motion Axis 127
Maximum Velocity
The steady-state speed of the axis, it is initially set to Tuning Speed by the
tuning process. This value is typically set to about 90% of the maximum speed
rating of the motor. This provides sufficient “head-room” for the axis to
operate at all times within the speed limitations of the motor. Any change in
value, caused by manually changing the spin control, is instantaneously sent to
the controller.
Maximum Acceleration
The maximum acceleration rate of the axis, in Position Units/second, it is
initially set to about 85% of the measured tuning acceleration rate by the
tuning process. If set manually, this value should typically be set to about 85%
of the maximum acceleration rate of the axis. This provides sufficient “
head-room” for the axis to operate at all times within the acceleration limits of
the drive and motor. Any change in value, caused by manually changing the
spin control, is instantaneously sent to the controller.
Maximum Deceleration
The maximum deceleration rate of the axis, in Position Units/second, it is
initially set to about 85% of the measured tuning deceleration rate by the
tuning process. If set manually, this value should typically be set to about 85%
of the maximum deceleration rate of the axis. This provides sufficient
“head-room” for the axis to operate at all times within the deceleration limits
of the drive and motor. Any change in value, caused by manually changing the
spin control, is instantaneously sent to the controller.
