Displaying the Conveyor Belt Speed
While the motor is operating, the speed of the motor output
shaft is displayed on the digital operator. To show the speed
of the conveyor belt (speed ft/minute), set the gear ratio to
the conveyor gear ratio in use.
1.
Calculate the conveyor gear ratio using the formula
below:
• Conveyor gear ratio =
• where:
• Gearhead ratio = ratio of inline or 90 degree gearbox
• Pulley diameter = Diameter of Drive Pulley (Ft)
- 2200 Series = 0.104
- 3200 Series = 0.25
- 2200 Precision Move End Drive Series = 0.125
- 2200 Precision Move Mid Drive Series = 0.167
- 3200 Precision Move End Drive Series = 0.275
- 2200 Modular Belt Series = 0.125
- 5300 Modular Belt Series = 0.325
- 5200 Modular Belt Series = 0.325
• Drive Sprocket Teeth = Number of teeth on sprocket
connected to gearmotor. Note: For all side drives = 1.
• Driven Sprocket Teeth = Number of teeth on sprocket
connected to conveyor shaft. Note: For all side drives = 1.
• Example:
- 2200 Series Conveyor with a 62M015PLBDDEN Gear-
motor and a light load bottom mount with a 44 tooth
pulley on the gearmotor and a 22 tooth pulley on the
conveyor.
• Conveyor gear ratio =
• Conveyor gear ratio = 21.5
