QUESTIONS		ANSWERS
The rated input voltage is 265VAC. The rated output voltage is 240VDC armature and 120VDC field. What output voltages does the speed control produce when it has 220VAC input?		This unit optimally runs on single phase 265VAC, and will also run at 220V but with a lower max output (you usually get 80% of the AC supply voltage in DC output voltage). A small boost transformer (240/24V) can bring you up to 265V. A 120VAC supply for the field supply section is also required.
What protection does the control provide against field loss?		The principle behind this design is that from zero speed you have full (120VDC) field supply and as you increase the armature voltage to approx 80%, the field output begins to drop to a min of 40V, allowing you to obtain the full RPM on the motor.
Does the control provide dynamic braking?		This unit has a built in field loss relay which shuts off the armature of the drive. The unit replaces only the tube section of the 10EE, leaving the original braking and contactor set intact.
Will the control maintain a constant speed under load?		As a DC drive you will get constant torque at all times.
Does the control require 3-phase power or single phase power or can it be run with either?		If you have three-phase AC, you can supply the unit with two legs.

This series of Solid State DC Motor Speed Controller
is rugged and industrial rated for reliable and dependable
operation in harsh environments. The self-regulating
Field Weakening capability makes this drive the perfect
cost-effective alternitive retrofit option for your Monarch 10EE Lathe,
or any other Shunt Wound Motor that requires field weakening.
The D510-FW allows you to retain the original configuration
of your lathe by keeping the DC Motor and headstock as is.
This unit is very user-friendly; It was designed to be installed
as easily as a plug n' play.
