3 Step Control Adder For Infinitely Variable
$485.21
3-step infinitely variable speed control adder for Harrington NER and ER series dual speed hoists with VFD control. It is added to the dual speed price, once for each infinitely variable directional axis.
It uses a 3-step button and the VFD to control the speed. It works like 2-step infinitely variable control, with an added deceleration function: press the button to the third step to accelerate, release it to the second step to hold the speed, and release it to the first step to decelerate. Pressing back to the second step holds the new speed.
