Optidrive™ variable speed drives have been successfully operating in a wide range of crane and hoist applications throughout the world for many years. Optidrive provides an excellent solution, allowing operation across a wide speed range whilst maintaining full load capability. This allows low speed movement for delicate operations requiring careful positioning and control to be achieved, whilst also allowing high speed movement to ensure operating time is minimised where practical.
Optidrive P2 provides proven high performance motor control, particularly suited to the demands of crane and hoist applications. Up to 200% of torque is available from zero speed, even in open loop applications without encoders fitted. Dedicated "Hoist Mode" operation ensures the motor brake is correctly and safely controlled, and maintains safe operating conditions at all times. In addition, this minimises wear on the hoist brake, and reduces mechanical shock loads, prolonging service life and reducing maintenance costs.
