NEXTMOVE PCI

Higher performance

1-8 axis Machine Controller

Positional Moves

Absolute & Relative moves allow high speed point to

point motion on one or all axes.

Speed, Acceleration & Deceleration can be defined

for each axis.

Trapezoidal profiled moves provide the fastest point to

point move but exert the maximum jerk and shock on

a system.

S-ramp profiled moves provide a more smooth velocity

profile that prolongs the life of machine mechanics.

Interpolated Moves

Linear Interpolation across any eight axes, (mixed

vector/servo/stepper) allows positional moves to be

defined in terms of a linear vectors. Absolute and

relative vectored moves are supported.

Circular Interpolation across any 4 pairs of axes

simultaneously (mixed vector/servo/stepper) allows a

complete or partial arc to be defined. Absolute and

relative circular moves are supported.

Contouring allows a string of linear and circular

interpolated moves to be blended together into a

continuous complex path of motion.

Splining allows a stream of moves, defined in terms

of position, velocity and time, to be blended together

into a continuous and smooth motion. This is used

in applications where path speed and continuous

velocity are important.

PC Communications

Dual Port RAM is used to communicate program,

data and control commands between the PC and

NextMove PCI card. This provides a very high speed

and efficient method of transferring information without

over burdening the PC and NextMove processors.

M a s t e r / F o l l o w e r

Electronic Cam replaces the traditional mechanical

cam with a servo motor and software programmable

cam profile. NextMove PCI supports one cam profile

for each of the eight axes (vector/servo or stepper).

Any axis may be defined as a Master input to a cam

and multiple master/cam relationships are supported.

Electronic Gearbox & Clutch enable two motor

shafts to be linked together in precise synchroniza-

tion with a software programmable gear ratio.

NextMove PCI allows any axis to be geared to any

master. Any axis may be defined as the master.

Multiple master/gear relationships are supported.

• 1 to 8 axes: 4 servo/vector plus 4

stepper. Expandable to twelve axes.

• 200 µS update time for four axes

• Dual port RAM interface to PC shipped

as standard.

• 200 nS position capture inputs.

• Digital and analog I/O.

• MINT™V4 or ‘C’ programming.

• CANopen protocol for distributed

control and peer to peer messaging

and control of third party products.

• Baldor CANbus port for distributed I/O

modules and operator interfaces.

• Multi-axis interpolation across twelve

axes when expansion card fitted.

• Gearing, CAMs, flying shears and much

more.

• 2 Mbytes of zero wait state RAM for

fast program execution.

• 24Kbytes of non-volatile memory for

user parameter storage.

P rogrammable Functions

NextMove PCl is programmed in MintV4 of Baldor’s easy to use MINT language, or in ‘C’. It offers greater

functionality and a more consistent relationship to ‘C’. Existing code can be quickly upgraded using Baldor’s

code analyzer tool which is shipped with all controllers. Both MINT and ‘C’ function libraries provide a wide

range of motion control functions outlined below and described more fully in the beginning of this section.
