SECTION 1 INTRODUCTION This manual provides instructions for Motoman’s Type I and Type II drive assemblies – MH75, MH150, MH450, MH1000, MH1500, and MH3000, headstocks, and headstock/tailstock combinations with MotoMount. MH-Series drive assemblies are used universally throughout Motoman’s product line. Appendix A and B of this manual contain parts lists with exploded views and performance specifications for the MH-Series.
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.
INTRODUCTION 1.2.3 System Layout – Type I The Type I MH-Series positioner kits include four drive assemblies: MH75, MH150, MH450, and MH1500. The kits are available in four basic mechanical configurations: the drive assembly, the drive assembly with MotoMount, the headstock positioner assembly, and the head and tailstock positioner assembly.

EQUIPMENT DESCRIPTION MotoMount MotoMount (see Figure 3-3) is a flexible tool fixture mounting system which improves tool repeatability and reduces loads on the headstock/tailstock bearing systems. MotoMount accommodates combined headstock/tailstock/tooling misalignments up to two (2) degrees. MotoMount is required for use with all Motoman MHT-series (headstock/ tailstock) positioners.
Figure 3-4 MotoMount HD Layout NS600 Module The NS600 motion-controlling package consists of a Yaskawa Electric America stand-alone servo amplifier with NS600 motion controller. This electrical sub- system can be interfaced with motors in the range of 550W – 1.5kW and 4.0kW –...
SECTION 4 INSTALLATION CAUTION! Installation of MotoMount and the MH–Series positioners is not a task for the novice. These components are not fragile, but should still be handled with care. Rough handling can damage system electronic components. Installation of the MH–Series positioner and MotoMount should be performed by personnel who are familiar with this Motoman product.
INSTALLATION Installing the MH-Series Drive Assembly – Type I 4.2.1 Site Preparation Each MH-Series drive assembly should be firmly mounted on a machine base or foundation rigid enough to withstand static and dynamic forces. 4.2.2 Unpacking The headstock and optional tailstock are shipped on a wood shipping skid. To unpack the equipment, proceed as follows: WARNING! See the specification tables in Section 3 for drive assembly weight.
INSTALLATION 4.2.3 Headstock Assembly Mounting Hole Pattern – MH75/175/450/1500 The headstock assembly may be mounted to the column assembly (see Section 4.2.4) or mounted to a customer-supplied machine base. For custom orientations, auxiliary mounting holes are provided on top of the drive assembly housing, and may be used in addition to the base mounting holes.

To unpack the equipment, proceed as follows: WARNING! The MH-series headstock can weigh as much as 1200 kg (2650 lbs).
INSTALLATION 4. Remove top cover and attach eye bolts to top of the housing and lift. 5. Place headstock in position. NOTE: Make sure there is adequate room on all sides of the positioner for parts fixturing. 4.3.3 Floor Mounting – Type II Figure 4-9 provides dimensions for accurately floor mounting the MH1000/3000 headstocks.

Connection to Motoman Controller When the MH-series drive assembly is delivered with a Motoman robot, connections between the two usually have been made at the factory, or if not, instructions for making connections can be found in the system manual.
INSTALLATION Tailstock Column Installation 4.4.1 Type I Installation Before proceeding to install the tailstock, make sure the Type I headstock is already anchored to the floor. If it is not, refer to Section 4.2. To install the tailstock onto a cell base or floor, proceed as follows: 1.
INSTALLATION 4.4.2 Type II Installation To install the tailstock of a Type II assembly onto a cell base or floor, proceed as follows: 1. Ensure the proper position the headstock assembly per system layout. The headstock must be permanently anchored to the floor/base. 2.
INSTALLATION 4.4.3 Leveling the Tailstock Type I Leveling Procedures The tailstock must be leveled in two directions, axially and cross-axially. Since it only taks three points to define a plane, use only three of the four leveling bolts to level the system. It is important to consistently use the same three leveling bolts throughout each process.
INSTALLATION Type II Leveling Procedures The Type II tailstock must be leveled in two directions, axially and cross-axially. Since it only takes three points to define a plane, use only three of the four leveling bolts to level the system. It is important to consistently use the same three leveling bolts through out each process.

Make certain servo power is OFF for the remainder of the installation, or serious operator injury and/or equipment damage...
INSTALLATION c) Ensure the bearing housing is perpendicular to the tailstock adapter within 1/2 degree (a visual check with a square is acceptable). d) Repeat this process until the gap at both positions is within 1 mm (.039 in.). If moving the bearing housing cannot provide the desired results, the columns are out of basic alignment and must be repositioned.
INSTALLATION The vertical alignment is checked by measuring the gap between the mounting fixture and mounting block. The measurement of this gap must not change more than 1 mm (.039 in.) after the headstock is rotated 180 degrees. To align MotoMount vertically, proceed as follows: 1.
INSTALLATION d) Recheck the alignment gap and verify that both gaps are within 1 mm (.039 in.). If multiple attempts fail to reduce the gap difference below 1 mm (.039 in.), contact Motoman Customer Service. e) Recheck the horizontal alignment. f) Insure ground cable is installed and properly secured.
INSTALLATION Installing Fixture Dowel Pins The dowel pins must be installed into the back of the mounting block before the assembly is mounted onto the faceplate. There are four holes in the back of the mounting block. See Figure 4-27 to determine which holes to use for your application.

Jog the headstock until MotoMount HD is horizontal. The tooling mounting holes and locating pin must be pointing up.
INSTALLATION Changing Adapter Shaft Position The preferred way change the adapter shaft position is to simply slide the tailstock adapter either way along the adapter shaft. If more adjustment is needed, loosen the four tailstock bolts and slide the adapter shaft and the tailstock adapter until a suitable position is acquired.
SECTION 5 TOOLING RECOMMENDATIONS Installation of tooling and fixtures should be performed by personnel who are familiar with the operation of this system. Tooling and fixtures are supplied by the customer. There are two system configurations possible with the MH-series positioners: headstock only and headstock/tailstock with MotoMount.
TOOLING RECOMMENDATIONS 5.1.1 Customer-supplied Tooling Fixture The customer-supplied tooling hangs from the faceplate as it supports production parts for welding.
