6.1.2 Slow Speed Mode
w In this mode, equipment will run only in slow speed, as chosen by setting the SLOW
START SPEED switches.
w The time setting indicated by the SLOW START TIME switches and the HIGH SPEED
switch settings will be invalid, and no speed change will occur.
w This mode is most applicable when high prevailing torque exists for the full duration of the
duty cycle, or long cycle time conditions allow for slower speeds.
6.1.3 Speed Change Operating Mode
w This mode starts in slow speed, and accelerates to high speed. The length of time spent in
slow speed prior to the speed change is regulated by setting the SLOW START TIME
switches.
w HIGH SPEED and SLOW START SPEED switches must also be set prior to operating in
this mode.
w The SPEED HIGH output is turned on when high speed is reached in this mode.
w This mode is most applicable when breakaway torque exists only for a short duration, and
high speed is desired for the remainder of the cycle. This is the most common mode for
back-out applications.
w Figure 6.1.3 illustrates speed and time set variables.
