FIG. 4-9-2 Setting Axis Unit / Spindle Number Ramp-Up Time Dip Switches
The dip switches are set by the factory to 250 milliseconds, and the maximum possible
duration is 500 milliseconds. Available ramp-up times and the appropriate dip switch settings
are given in the table below. Setting the switches in any other combination will result in an
erroneous setup.
OFF OFF ON ON .10 SECOND
OFF ON OFF ON .25 SECOND
ON OFF OFF ON .50 SECOND
OFF OFF OFF ON 1.0 SECOND
500 msec
Switch 1 250 msec
Switch 2 100 msec
Switch 3 0 msec
Switch 4 RAMP-UP
DURATION
Note: Newer Axis Units with a model number ending in "A" are also preset to 250 milliseconds, but
the Axis Unit cover must be removed to access the dip switches if a different setting is
required. Figure 4-9-2 illustrates the dip switch access found only on older style Axis Units.
4.9.2 Ramp-Up Time Setup
The ramp-up time dip switches control the duration of the initial tool speed ramp-up. If the
duration is too short, the tool starting inertia may be falsely sensed by the System as a torque
reading. If the duration is too long, the extended cycle time will result in reduced System
efficiency.
