We are dealing only crane duty drives especially for vertical
hoist application for heavy industrial application. The general application
drives have not below crane function
Open loop
For open loop operation, Danfoss drives help to ensure excellent crane
performance without encoders. The crane is simple to commission for travel and
hoist. For parallel operation of two motors, droop control equalizes torque
between the two motors.
Closed
loop
Cranes achieve better dynamics in closed loop operation. Danfoss offers
flexible encoder interfaces, enabling broader choice of components
Advanced
mechanical brake control
Danfoss drives prevent load shocks at start and stop of
lifting. For vertical motion, Danfoss provides smooth torque ramping to ensure
that the load is held, stopped, raised and lowered in a perfectly safe mode at
all times.
