Figure 1.6 – Preset Slow Speed Option
Important: Slow speed running is not intended for continuous operation due
to reduced motor cooling. The two starts per hour limitation also applies to
slow speed operation. This option employs a cycle-skipping scheme which
produces limited torque. Applications should be checked with the factory.
