Product Overview Chapter 1
Preset Slow Speed
This option can be used in applications that require a slow-speed jog for general
purpose positioning. Preset Slow Speed provides either 7% of base speed (low) or
15% of base speed (high) settings in the forward direction. Reverse can also be
programmed and offers 10% of base speed (low) and 20% of base speed (high)
settings.

Run
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.
