System Overview
The Motoman Type I and Type II MH-Series drive assemblies provide precision-
controlled rotary motion and can be mounted in any orientation the welding,
material handling, or dispensing application may require. The standard
configuration uses an AC servo motor, a high-ratio gear reducer with integral
output bearing, faceplate, and a cast iron housing. It also includes dual integral
position switches and one or more weld ground brushes rated at 400 amps per
brush.
The MotoMount tool mounting system is a modular accessory for MHT (Motoman
Headstock/Tailstock) positioners and provides improved repeatability as compared
to hard-mounted tooling systems. It eliminates headstock bearing loads induced by
tooling and head/tailstock misalignments, up to a maximum of two (2) degrees.
MotoMount also decreases moment forces on the headstock bearing by up to 70
percent on a 3-meter (118.1-inch) span, and affords even higher reductions on
longer spans. This improves headstock life by minimizing wear on the reducer gear
and bearings. MotoMount eliminates the need for costly machine bases or use of
surveying tools (transits) for precise headstock/tailstock alignment, thus reducing
overall positioner cost and installation time. The system includes a headstock
fixture assembly, a compliant tailstock bearing, a tailstock tooling adapter, and
mounting hardware.
1.2.1
NS600 Module
The NS600 control solution uses Yaskawa Electric America (YEA) components;
specifically an amplifier and the NS600 motion control option. The NS600 selects
motions via a binary input pattern received from standard XRC outputs. Motion
progress/status is transmitted to the XRC via outputs from the NS600. This
handshaking interaction of the inputs and outputs creates the loss of coordinated
motion, a feature that can be desirable in certain applications.
1.2.2
MotoMount
MotoMount is standard equipment with all MHT positioner assemblies. It may be
purchased for any MH-Series drive assembly for applications requiring custom
headstock/tailstock supporting structures.
WARNING!
Do not use MotoMount with stand-alone headstock (no tailstock)
applications. Use in a stand-alone application will result in
uncontrolled tooling motion.
NOTE:
If customers want to integrate a Motoman drive assembly or headstock assembly with their own
tailstock, they must order the MotoMount system. Failure to use MotoMount with a Motoman
drive assembly or headstock assembly will void the warranty.
