brake fails, a brake on the load side of the machine will be able to stop a falling load. The Stagehand
Pro 3 expects that the load brake will be fully released within 500ms of receiving power.
If a brake is used on the output side (aka load side) of a speed reducer, then it must be much larger
than the motor side brake since it isn’t able to use the mechanical advantage of the speed reducer to
increase its holding power. Load brakes are not required on all machines. The additional expense is
often not incurred for machines that are moving scenery laterally. For instance, our Pushstick deck
winches do not have a load brake, but our Spotline hoist does use a load brake.
Now that we have an understanding of the terminology the pin-out of the Motor and Brakes
connector shown below has more relevance:

Motor Power – 230VAC 3P 24A max, variable frequency from 0.5Hz-60Hz
● Motor Brake Power – 208/230VAC 1P 5A max 50/60Hz.
●
Motor Brake Fast Switching Circuit – if you are using a DC brake with a rectifier that offers DC
switching you can use this circuit to interrupt the DC power to the brake which will greatly
reduce the time it takes to engage the brake.
