Formax PowerMax 3000 - Knife; Knife Motor; Knife Retract Actuator

KNIFE: The Knife slices the product as it feeds through the
Shear Bar. (Illustration 21) The Knife mounts to an Orbiting
Head and Counterweight. The Knife is the primary component
of the Slicer. For optimum slicing performance, it is necessary
to keep the Knife sharp and in good condition.
KNIFE MOTOR: The M1 Servo Motor drives the Head
Assembly that turns the Knife in a counter-clockwise rotation
with a belt and pulley. (Illustration 22) The M1 Servo Motor is
controlled by the U1 Servo Drive. The maximum speed of the
M1 Head Motor turns the Knife at 2000 RPM. The Head Motor
has an internal magnetic brake. In case of a power loss, the
Brake will de-energize and engage 2 magnetic friction plates
and stop the Servo Motor. The Brake is not used in a normal
“Cycle Stop.” When a “Master Off” is pressed or a Guard is
opened while the Slicer is running, the U4 Servo Drive will
ramp down and stop the motor. The Internal Brake in the Knife
Motor will engage after 4 seconds and hold the Knife
stationary.
KNIFE RETRACT ACTUATOR: The Knife moves away from
the product after each stack or draft is completed.
(Illustration 22) The M2 Knife Retract Servo Motor directly
drives a “linear actuator” that moves the Knife towards and
away from the Shear Bar. The M2 Servo Motor is controlled by
the U5 Servo Drive.
