The VMK hoists are equipped with high resolution incremental encoders that make it possible to position the hoist to within +/- 1 mm (in combination with V-Motion) permitting precise target runs with the highest degree of reproducible accuracy. Combined with the V-Motion controller modules, the VMK hoists can execute variable speed runs for path and time synchronized runs; whilst with the MPC 4IC1 controllers, fixed speed runs of up to 12 m/min are possible.
Used in conjunction with V-MOTION controllers, speeds from 0 to 29 m/min are possible - as a closed loop system with full torque even for runs over the zero point (reversal of the run direction without the intervention of the brakes). This is particularly useful in the theatre, as it makes it possible to perform complex changes of scenery smoothly, silently and without interruption say the company.
