DIGITAL OUTPUTS

12 digital outputs, which may be user configured for

drive enable, error or general purpose outputs. A

removable output module is fitted to the Nextmove

PCI allowing the type of output to be adapted to the

application requirements. NPN (FET) or PNP

(Darlington) output modules are available. PNP

shipped as standard.

PNP OUTPUT Module – shipped as standard with

every Nextmove PCI controller.

ENCODER INPUTS

One per servo axis, plus one Master per card. An

additional four encoder channels are available on

NextMove PCI expansion option card. Incremental

encoder for position feedback. Operates with

differential (TTL or RS422) outputs only. Accepts

three channel encoder (A, !A, B, !B, Z, !Z). A & B

channels are quadrature decoded. Maximum encoder

frequency is 7.5 million quadrature counts per

second.

ANALOGUE AMPLIFIER COMMAND OUTPUT

One per servo axis up to a maximum of four. Ò10V,

14 bit command output. An additional four command

outputs are available on NextMove PCI expansion

option card.

ANALOGUE INPUTS

4 x 12 bit resolution, differential inputs. ±5V±10V,

0-10V or 0-5V voltage ranges can be set by the user

in software.

STEPPER OUTPUTS

NMPCI can be supplied with up to four axis of

stepper. One Step and one Direction output per

stepper axis.Signals from the NextMove PCI card are

5V TTL single ended signals. Output signals from the

NextMove PCI breakout card are 5V differential line

drivers. Maximum frequency is 3 million pulses per

second.

PROGRAM MEMORY

2 Mbyte of RAM for storage of operating system,

user program and data. The operating system is

downloaded to the NextMove PCI via the dual port

RAM interface. In addition to this there is 24 Kbytes

of auto storing non volatile RAM (does not require a

battery) for non-volatile variable storage.

CANBUS CHANNELS

NMPCI has two CANbus channels. CAN channel 1 is

used to connect to third party CANopen devices such

as operator panels, pneumatic valve manifolds,

analogue and digital I/O blocks. The output signals

from the NextMove PCI require CAN transceivers to

be fitted. Opto-isolated CAN transceivers are fitted to

the NextMove PCI breakout unit are as standard.

See accessories.

CAN channel 2 is used to connect to Baldor’s range

of I/O modules and operator panels. See

accessories. The output signals from the NextMove

PCI require CAN transceivers to be fitted. Non-

isolated CAN transceivers are fitted to the NextMove

PCI breakout unit are as standard.

DUAL PORT RAM

Shipped as standard with all NextMove PCI

controllers. A 4K x 32 (16 Kbytes) dual port RAM

connects directly to the 33MHz, 32 bit PCI interface

to provide very high speed data transfer.

EXPANSION OPTIONS

Additional stepper outputs and/or analogue drive

command outputs may be added using one of

Baldor’s NextMove PCI expansion cards. See the

accessories section.

100 PIN CONNECTOR

All signal connections are made through a single 100

way connector. This provides a clean and EMC

compliant connection the the Baldor breakout unit.

Please note that this connector is different from our

NextMove PC connector.

RELAY OUTPUT

One per controller. Form C (SPDT) rated at 24V DC,

150mA. Common, normally open, normally closed

connections. Relay de-energizes on the occurrence

of an error condition. The type of activating error

POWER REQUIREMENTS

Power taken from PCI bus: +5V (1500mA), +12V

(100mA), -12V (100mA). (15W PCI class)

External power required for opto-isolated outputs: up

to 850mA.
