FIG. 4-10-3 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.

4.10.3 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.
