direction. Reverse can also be programmed and offers 10% of base speed

(low) and 20% of base speed (high) settings.

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.
