4.2.2 Analog outputs

The four analog outputs are available on connector X13, as shown in section 4.1.1.

H Four independent bipolar analog outputs.

H Output range: ±10 VDC (±0.1%).

H Resolution: 12-bit.

H Output current: 10 mA maximum.

H Update frequency: 1 kHz.

Mint and the Mint Motion Library use analog outputs Demand0 to Demand2 to control local drive
amplifiers. Demand outputs 0 to 2 are used by axes configured as servo (see section 5.5.3). All
of the outputs may be used as general purpose analog outputs, provided they have not been
assigned to an axis - see the DAC keyword in the Mint help file.

The analog outputs may be used to drive loads of 1 kΩ or greater. Shielded twisted pair cable
should be used. The shield connection should be made at one end only.

4.3 Digital I/O

The NextMove e100 provides:

H 20 general purpose digital inputs.

H 12 general purpose digital outputs.

H 1 general purpose relay output.

4.3.1 Digital inputs

Digital inputs are available on connectors X8, X9 and X10, as shown in section 4.1.1.
The digital inputs are arranged in three groups, each with their own common connection. This
allows each group to be configured independently for ‘active high’ or ‘active low’ operation (using
the Mint INPUTMODE keyword).

The general purpose digital inputs DIN0 - DIN19 can be shared between axes, and are
programmable in Mint (using a range of keywords beginning with the letters INPUT... ) to
determine their active level and if they should be edge triggered. The state of individual inputs can
be read directly using the INX and INSTATEX keywords. See the Mint help file.

A general purpose digital input can be assigned to a special purpose function such as a home,
limit, stop or error input. See the keywords HOMEINPUT, LIMITFORWARDINPUT,
LIMITREVERSEINPUT, STOPINPUT and ERRORINPUT in the Mint help file.

4.3.1.1 DIN0 - DIN3

Digital inputs DIN0 to DIN3 can be assigned as fast interrupts. These are used as high speed
position latches, allowing any combination of axes to be captured by the hardware. The latency
between input triggering and capture is 1 μs. Special Mint keywords (beginning with the letters
LATCH...) allow specific functions to be performed as a result of fast position inputs becoming
active. See the Mint help file for details.

4.3.2 Digital outputs and relay

The digital outputs are available on connectors X4 and X11, as shown in section 4.1.1.
A digital output can be configured in Mint as a general purpose output, a drive enable output or
a global error output. Outputs can be controlled directly from Mint WorkBench, or by the Mint OUT
and OUTX keywords. Outputs can be shared between axes and can be configured using Mint
WorkBench (or the OUTPUTACTIVELEVEL keyword) to determine their active level.

4.3.2.1 DOUT0 - DOUT7

An external supply (typically 24 VDC) is used to power the UDN2982 output devices, as shown
in Figure 15. When an output is activated, current is sourced from the user supply through a
UDN2982 output driver.

H A total of 500 mA may be sourced by DOUT0 - DOUT7, providing an average 62.5 mA per

output when all outputs are on (100% duty cycle, 24 V supply). If the total current exceeds
1 A a self-resetting fuse will operate, which may take a few minutes to reset.

H An individual output can provide a maximum continuous current of 350 mA, but if

other

outputs are being used the total current must not exceed 500 mA

.

H The maximum allowable power dissipation for the UDN2982 driver is 1.5 W.

If an output is used to drive an inductive load such as a relay, a suitably rated diode must be fitted
across the relay coil, observing the correct polarity. The use of shielded cable is recommended.

UDN2982 output driver. Because only four of the UDN2982’s eight outputs are being used, the
average current available on DOUT8 - DOUT11 is increased:

H A total of 500 mA may be sourced by DOUT8 - DOUT11, providing an average 125 mA per

output when all outputs are on (100% duty cycle, 24 V supply). If the total current exceeds
1 A a self-resetting fuse will operate, which may take a few minutes to reset.

The relay connections are available on connector X12, as shown in section 4.1.1. The relay
outputs are isolated from any internal circuits in the NextMove e100. In normal operation, while
there is no error, the relay is energized and REL COM is connected to REL NO. In the event of
an error or power loss, the relay is de-energized, and REL COM is connected to REL NC. For
control purposes the relay is considered to be another digital output (DOUT12), and can be
controlled directly using the Mint OUT or OUTX keywords. The relay can be configured as the
global error output by setting GLOBALERROROUTPUT to 12. See the Mint help file.

4.3.3 Stepper control outputs - models NXE100-16xxDx

The stepper control outputs are available on connectors X2 and X3, as shown in section 4.1.1.

There are four sets of stepper motor control outputs, operating in the range 60 Hz to 5 MHz. Each
of the step (pulse) and direction signals from the NextMove e100 is driven by DS26LS31 line
drivers, providing RS422 differential outputs. It is recommended to use separate shielded cables
for the step outputs. The shield should be connected at one end only.

The STEPPERDELAY keyword allows a 0 - 4.25 μs delay to be introduced between state
changes of the step and direction outputs. The FREQ keyword can be used to directly control the
output frequency, between 60 Hz and 5 MHz. Values less than 60 Hz will produce no output - see
the Mint help file.

The DS26LS31 drivers are static sensitive devices. Take appropriate ESD
precautions when handling the NextMove e100. When connecting the outputs to
single ended inputs as shown in Figures 17 and 18, do not connect the STEPx-or
DIRx- outputs to ground; leave them unconnected.

4.3.4 Stepper control outputs - models NXE100-16xxSx

The stepper control outputs are available on connectors X2 and X3, as shown in section 4.1.1.
There are four sets of stepper motor control outputs, operating in the range 60 Hz to 500 kHz.
Each of the step (pulse) and direction signals from the NextMove e100 is driven by a ULN2803
open collector Darlington output device. The STEPPERDELAY keyword allows a 0 - 4.25 μs delay
to be introduced between state changes of the step and direction outputs. The FREQ keyword
can be used to directly control the output frequency, between 60 Hz and 500 kHz. Values less
than 60 Hz will produce no output - see the Mint help file.

The ULN2003 drivers are static sensitive devices. Take appropriate ESD
precautions when handling the NextMove e100. A 5 V supply is provided on
connectors X2 and X3 for powering external circuits, as shown in Figure 19. The
same 5 V supply is also present on connectors X5, X6 and X7 for powering
encoders. Ensure that the total combined current demand of all 5 V outputs does not
exceed 600 mA. In situations where induced noise is affecting a step or direction
output, it may be necessary to connect a 5 kΩ or 10 kΩ pull-up resistor between the
output and the 5 V supply (pin 4).

resistors and terminators. Encoders must provide RS422 differential signals. The use of
individually shielded twisted pair cable is recommended. A 5 V supply is provided on connectors
X5, X6 and X7 for powering the encoders. On models NXE100-16xxSx, the same 5 V supply is
also present on connectors X2 and X3 for powering external circuits (see section 4.3.4). Ensure
that the total combined current demand of all 5 V outputs does not exceed 600 mA. If the total

The maximum encoder input frequency is affected by the length of the encoder cables.
The theoretical maximum frequency is 20 million quadrature counts per second. This is
equivalent to a maximum frequency for the A and B signals of 5 MHz. However, the effect of
cable length is shown in Table 1:

In many networking environments, the node ID may also be referred to as the address. On EPL
networks, limitations apply to the node IDs that may be selected:

H Node ID 0 (00) is reserved for special purposes and cannot be used.

H Node IDs 1 - 239 (01 - EF) cause the node to become a ‘controlled node’, a node that will

accept commands from the manager node.

H Node ID 240 (F0) causes the node to become the ‘manager node’, a node that will control the

timing and issue commands to controlled nodes. There must only be one manager node on
the network.

H Node IDs 241 - 255 (F1 - FF) are reserved for special purposes and cannot be used.

For all other communication channels such as CANopen, USB and serial, the node ID is set in
software. Each channel can have a different node ID, selected using the Mint WorkBench
Connectivity Wizard or the Mint BUSNODE keyword. See the Mint help file for details.

The USB connector is used to connect the NextMove e100 to a PC running Mint WorkBench.
The NextMove e100 is a self-powered, USB 1.1 (12 Mbps) compatible device. If it is connected
to a slower USB1.0 host PC or hub, communication speed will be limited to the USB1.0
specification (1.5 Mbps). If it is connected to a faster USB2.0 (480 Mbps) host PC or hub,
communication speed will remain at the USB1.1 specification of the NextMove e100.

Ideally, the NextMove e100 should be connected directly to a USB port on the host PC. If it is
connected to a hub shared by other USB devices, communication could be affected by the
activity of the other devices. A 2 m (6.5 ft) standard USB cable is supplied. The maximum
recommended cable length is 5 m (16.4 ft).

NextMove e100 provides a selectable RS232 or
RS485/422 serial port for programming, connection to an
HMI operator panel, or for communication with other
devices such as PLCs or other Baldor servo drives. The
port is fully ESD protected to IEC 1000-4-2 (15 kV). When
the NextMove e100 is connected to Mint WorkBench, the
Connectivity Wizard can be used to configure the serial
port. The configuration can also be changed using the Mint
keyword SERIALBAUD (see the Mint help file for details).
The value is restored at power up. The port is capable of
operation at up to 115.2 Kbaud.

4.5.3 Using RS232

The NextMove e100 has a full-duplex RS232 serial port with the following preset configuration:

H 57.6 Kbaud
H 1startbit
H 8 data bits
H 1stopbit
H No parity
H Hardware handshaking lines RTS and CTS must be connected.

The RS232 port is configured as a DCE (Data Communications Equipment) unit so it is possible
to operate the controller with any DCE or DTE (Data Terminal Equipment). Full duplex
transmission with hardware handshaking is supported. Only the TXD, RXD and 0V GND
connections are required for communication, but since many devices will check the RTS and
CTS lines, these must also be connected. Pins 4 and 6 are linked on the NextMove e100. The
maximum recommended cable length is 3 m (10 ft) at 57.6 Kbaud (the factory preset rate). When
using lower baud rates, longer cable lengths may be used up to maximum of 15 m (49 ft) at 9600
baud.

4.5.4 Multidrop using RS485 / RS422

Multidrop systems allow one device to act as a ‘network master’, controlling and interacting with
the other (slave) devices on the network. The network master can be a controller such as
NextMove e100, a host application such as Mint WorkBench (or other custom application), or a
programmable logic controller (PLC). RS422 may be used for multi-drop applications as shown
in Figure 23. Four-wire RS485 may be used for single point-to-point applications involving only
one Baldor controller. If firmware is updated over RS485/RS422, it can only be downloaded to
the controller that was chosen in the Select Controller dialog in Mint WorkBench.

Figure 23 - 4-wire RS422 multi-drop connections

Each transmit/receive (TX/RX) network requires a termination resistor at the final RX connection,
but intermediate devices must not be fitted with termination resistors. An exception is where
repeaters are being used which may correctly contain termination resistors. Termination
resistors are used to match the impedance of the load to the impedance of the transmission line

Input / Output 4-23MN1941

(cable) being used. Unmatched impedance causes the transmitted signal to not be fully
absorbed by the load. This causes a portion of the signal to be reflected back into the
transmission line as noise. If the source impedance, transmission line impedance, and load
impedance are all equal, the reflections (noise) are eliminated. Termination resistors increase the
load current and sometimes change the bias requirements and increase the complexity of the
system.

4.5.5 Connecting serial Baldor HMI Operator Panels

Serial Baldor HMI Operator Panels use a 15-pin male D-type connector (marked PLC PORT),
but the NextMove e100 Serial connector uses a 9-pin male D-type connector. The

4.6 Ethernet interface

The Ethernet interface provides TCP/IP and ETHERNET Powerlink networking capabilities.

4.6.1 TCP/IP

Transmission Control Protocol / Internet Protocol (TCP/IP) is a common set of protocols used to
transfer information between devices over a network, including the internet. TCP enables two
devices to establish a connection, and guarantees the delivery of packets (datagrams) of
information in the correct order. IP specifies the format of the individual packets (which includes
the destination address of the receiving device) but has no influence on whether the packet is
delivered correctly.

TCP/IP allows the NextMove e100 to support standard Ethernet communication with a host PC
running Mint WorkBench. The connection uses Baldor’s high level ICM (Immediate Command
Mode) protocol to allow Mint commands, Mint programs and even firmware to be sent to the
controller over the Ethernet network.

When operating in standard Ethernet mode, TCP/IP cannot be used to communicate with a
controller on a daisy-chained network. This is due to cumulative timing errors caused by each
controller.s internal hub. It is necessary to connect the host PC to the controller either directly or
via a switch or hub, as shown in Figure 26. A switch is preferable to a hub as it will provide faster
performance when there is a large amount of data being transmitted.

Figure 26 - Connecting to controllers using TCP/IP in standard Ethernet mode

When operating in EPL mode, in conjunction with an EPL compatible router, the host PC can use
TCP/IP to communicate with controllers on a daisy-chained network. In this situation, the router
will use TCP/IP only within EPL’s asynchronous time slots. See the Mint help file for further
details.

4.6.2 ETHERNET Powerlink

NextMove e100 supports the deterministic ETHERNET Powerlink (EPL) protocol. This protocol
provides very precise and predictable ‘real-time’ communication over a 100 Mbit/s (100Base-T)
Fast Ethernet (IEEE 802.3u) connection. This makes it suitable for the transmission of control
and feedback signals between the NextMove e100 and other EPL enabled controllers such as
MicroFlex e100. The EPL protocol implemented in Mint is based on the CANopen DS402 Device
Profile for Drives and Motion Control.

NextMove e100 incorporates a built-in repeating hub, providing two ports for connection to other
equipment. This allows nodes to be connected as a ‘daisy-chain’ network of up to 10 nodes,
avoiding the need for additional hubs. If the network comprises more than 10 nodes, an external
hub must be used. The structure of the physical network is informal so does not need to reflect
the logical relationship between nodes. Ethernet switches must not be used in EPL networks as
their timing cannot be guaranteed.

To connect the NextMove e100 to other EPL devices use CAT5e Ethernet cables - either S/UTP
(unshielded screened/foiled twisted pairs) or preferably S/FTP (fully shielded screened/foiled
twisted pairs). To ensure CE compliance, Ethernet cables longer than 3 m should be S/FTP
cables bonded to the metal backplane at both endes using conductive clamps (see section
B.1.5). Cables may be up to 100 m (328 ft) long. Two varieties of CAT5e cable are available;
‘straight’ or ‘crossed’. Straight cables have the TX pins of the connector at one end of the cable
wired to the TX pins of the RJ45 connector at the other end of the cable. Crossover cables have
the TX pins of the connector at one end of the cable wired to the RX pins of the RJ45 connector
at the other end of the cable.

Provided the network consists of only Baldor EPL controllers and drives (and any hub), straight
or crossed cables may be used. This is because many Ethernet devices, including hubs and all
Baldor EPL products, incorporate Auto-MDIX switching technology which automatically
compensates for the wiring of the straight cable. However, if other manufacturer’s EPL nodes are
included in the EPL network, crossover cables should be used as recommended by the
ETHERNET Powerlink Standardization Group (EPSG).

The NextMove e100 Ethernet interface is galvanically isolated from the rest of the
NextMove e100 circuitry by magnetic isolation modules incorporated in each of the Ethernet
connectors. This provides protection up to 1.5 kV. The connector/cable screen is connected
directly to the chassis earth of the NextMove e100. For additional noise immunity, especially
where Ethernet cables are frequently unplugged, it is recommended to clamp the outer shields
of Ethernet cables to an earth point. Termination components are incorporated in each of the
Ethernet connectors, so no further termination is required.

The EPL network supports the 100Base-TX (100 Mbit/s) system only, so attempting to connect
slower 10Base-T (10 Mbit/s) nodes will cause a network error.

4.7 CAN interface

The CAN bus is a serial based network originally developed for automotive applications, but now
used for a wide range of industrial applications. It offers low-cost serial communications with
very high reliability in an industrial environment; the probability of an undetected error is

4.7x10

-11

. It is optimized for the transmission of small data packets and therefore offers fast

update of I/O devices (peripheral devices) connected to the bus.

The CAN protocol only defines the physical attributes of the network, i.e. the electrical,
mechanical, functional and procedural parameters of the physical connection between devices.
The higher level network functionality on NextMove e100 is defined by the CANopen protocol,
one of the most used standards for machine control.

4.7.2 CAN wiring

A very low error bit rate over CAN can only be achieved with a suitable wiring scheme, so the
following points should be observed:

H The two-wire data bus line may be routed parallel, twisted and/or shielded, depending on

EMC requirements. Baldor recommend a twisted pair cable with the shield/screen
connected to the connector backshell, in order to reduce RF emissions and provide immunity
to conducted interference.

H The bus must be terminated at both ends only (not at intermediate points) with resistors of a

nominal value of 120 Ω. This is to reduce reflections of the electrical signals on the bus,
which helps a node to interpret the bus voltage levels correctly. If the NextMove e100 is at
the end of the network then ensure that a 120 Ω terminating resistor is fitted (normally inside
the D-type connector).

1 5

6 9

www.baldormotion.com

4-28 Input / Output MN1941

H All cables and connectors should have a nominal impedance of 120 Ω. Cables should have

a length related resistance of 70 mΩ/m and a nominal line delay of 5 ns/m.

H The maximum bus length depends on the bit-timing

configuration (baud rate). The table opposite shows
the approximate maximum bus length (worst-case),
assuming 5 ns/m propagation delay and a total
effective device internal in-out delay of 210 ns at
1 Mbit/s, 300 ns at 500 - 250 Kbit/s, 450 ns at
125 Kbit/s and 1.5 ms at 50 - 10 Kbit/s.

(1)

For bus lengths greater than about 1000 m,
bridge or repeater devices may be needed.

H The compromise between bus length and CAN baud

rate must be determined for each application. The
CAN baud rate can be set using the BUSBAUD keyword. It is essential that all nodes on the
network are configured to run at the same baud rate.

H The wiring topology of a CAN network should be as close as possible to a single line/bus

structure. However, stub lines are allowed provided they are kept to a minimum (<0.3 m at
1 Mbit/s).

H The 0 V connection of all of the nodes on the network must be tied together through the CAN

cabling. This ensures that the CAN signal levels transmitted by NextMove e100 or CAN
peripheral devices are within the common mode range of the receiver circuitry of other nodes
on the network.

4.7.2.1 Opto-isolation

On the NextMove e100, the CAN channel is opto-isolated. A voltage in the range 12-24 V must
be applied between pin 9 (+24 V) and pin 3 or 6 (0 V) of the CAN connector. From this supply,
an internal voltage regulator provides the 5 V at 100 mA required for the isolated CAN circuit.
A connector such as the Phoenix Contact SUBCON-PLUS F3 (Phoenix part 2761871) provides
a 9-pin D-type female connector with easily accessible terminal block connections. CAN cables
supplied by Baldor are ‘category 5’ and have a maximum current rating of 1 A, so the maximum
number of NextMove e100 units that may be used on one network is limited to ten.

4.7.3 CANopen

Baldor have implemented a CANopen protocol in Mint (based on the ‘Communication Profile’ CiA
DS-301) which supports both direct access to device parameters and time-critical process data
communication. The NextMove e100 complies with CANopen slave device profile DS402, and
can be a DS401 or DS403 master device. It is able to support and communicate with a variety of
devices including:

H Any third party digital and analog I/O device that is compliant with the ‘Device Profile for

Generic I/O Modules’ (CiA DS-401).

H Baldor HMI (Human Machine Interface) operator panels, which are based on the ‘Device

Profile for Human Machine Interfaces’ (DS403).

H Other Baldor controllers with CANopen support for peer-to-peer access using extensions to

the CiA specifications (DS301 and DS302).

The functionality and characteristics of all Baldor CANopen devices are defined in individual
standardized (ASCII format) Electronic Data Sheets (EDS) which can be found on the Baldor
Motion Toolkit CD supplied with your product, or downloaded from

Note: The NextMove e100 CAN channel is opto-isolated, so a voltage in the range

12-24 V must be applied between pin 9 and pin 6 of the CAN connector.

The configuration and management of a CANopen network must be carried out by a single node
acting as the network master. This role can be performed by the NextMove e100 when it is
configured to be the Network Manager node (node ID 1), or by a third party CANopen master
device.

Up to 126 CANopen nodes (node IDs 2 to 127) can be added to the network by a NextMove e100
Manager node using the Mint NODESCAN keyword. If successful, the nodes can then be
connected to using the Mint CONNECT keyword. Any network and node related events can then
be monitored using the Mint BUS1 event.

Note: All CAN related Mint keywords are referenced to CANopen using the ‘bus’ dot

parameter. For CANopen the ‘bus’ dot parameter must be set to 1.

Please refer to the Mint help file for further details on CANopen, Mint keywords and dot
parameters.

5.1 Introduction

Before powering the NextMove e100 you will need to connect it to the PC using a USB or
Ethernet cable and install the supplied Mint Machine Center software. This software includes a
number of applications and utilities to allow you to configure and program the NextMove e100. If
you do not have experience of software installation or Windows applications you may need
further assistance for this stage of the installation. The Baldor Motion Toolkit CD containing the
software can be found separately within the packaging.

5.1.1 Connecting the NextMove e100 to the PC

The NextMove e100 can be connected to the PC using either USB, TCP/IP , RS232, or
RS485/422.

To use USB, connect a USB cable between a PC USB port and the NextMove e100 USB port.
Your PC must be using Windows 2000, Windows XP or Windows Vista.

To use TCP/IP, connect a CAT5e Ethernet cable between the PC and one of the NextMove e100
Ethernet ports.

You cannot connect an ordinary office PC to the NextMove e100 without first altering
the PC’s Ethernet adapter configuration. However, if you have installed a second
Ethernet adapter dedicated for use with the NextMove e100, then this adapter’s
configuration can be altered without affecting the PC’s office Ethernet connection. If
you are unsure about making changes to your PC’s Ethernet adapter configuration,
or are prevented by user permission levels, ask your I.T. administrator to assist you.

If there is a EPL manager node (node ID 240) on the Ethernet network, then the
network will be operating in EPL mode. This means any TCP/IP connection from the
PC must pass through an EPL compatible router.

To use RS232 or RS485/422, connect an appropriate serial cable between the PC and the
NextMove e100 serial port. If you are using an intermediate RS485 to RS232 converter, connect
this as specified by the manufacturer. Mint WorkBench can scan all the PC’s COM ports, so you
can use any port.

5.1.2 Installing Mint Machine Center and Mint WorkBench

You need to install the Mint Machine Center (MMC) and Mint WorkBench. Any previous versions
of MMC or Mint WorkBench must be uninstalled before proceeding with this installation:

1. Insert the CD into the drive.

2. After a few seconds the setup wizard should start automatically. If the setup wizard does not

appear, select Run... from the Windows Start menu and type

d:\start

where d represents the drive letter of the CD device.

Follow the on-screen instructions to install MMC (including Mint WorkBench). The setup
wizard will copy the files to appropriate folders within the C:\Program Files folder, and place
shortcuts on the Windows Start menu.

Operation 5-3MN1941

5.2 Starting the NextMove e100

If you have followed the instructions in the previous sections, you should have now connected
the power sources, inputs and outputs and the USB, serial, or Ethernet cable linking the PC to the
NextMove e100.

5.2.1 Preliminary checks

Before you apply power for the first time, it is very important to verify the following:

H Disconnect the load from the motor until instructed to apply a load.

H Inspect all power connections for accuracy, workmanship and tightness.

H Verify that all wiring conforms to applicable codes.

H Verify that the NextMove e100 is properly earthed/grounded.

H Check all signal wiring for accuracy.

5.2.2 Power on checks

1. Turn on the 24 VDC control supply.

2. Within approximately 20-30 seconds or less, the test sequence should complete and the
Status LED should start to flash green. If the Status LED is not lit then re-check the power
supply connections. If the Status LED flashes red, this indicates that the NextMove e100 has
detected a fault - see section 6.

5.2.3 Installing the USB driver

If you have connected the NextMove e100 to the PC using the USB connection, it will be
necessary to install the USB driver. When the NextMove e100 is powered, Windows will
automatically detect the controller and request the driver. The driver consists of two files,
USBmotion.inf and USBmotion.sys. Both files must be present for installation.

1. Follow the on-screen instructions to select and install the driver. The driver files are available
on the supplied Baldor Motion Toolkit CD. If you are using a copy of the driver located on the
hard disk, a floppy disk or another CD, the two driver files must be in the same folder.

2. During installation, Windows may report that the driver is ‘unsigned’. This is normal for the
NextMove e100 driver, so click the Continue Anyway button to continue with the installation.
When installation is complete, a new USB Motion Controller device will be listed in the
Universal Serial Bus controllers section of Windows Device Manager.

The NextMove e100 is now ready to be configured using MMC and Mint WorkBench.

Note: If the NextMove e100 is later connected to a different USB port on the host

computer, Windows may report that it has found new hardware. Either install the
driver files again for the new USB port, or connect the NextMove e100 to the original
USB port where it will be recognized in the usual way.

5.2.4 Configuring the TCP/IP connection (optional)

If you have connected the NextMove e100 to the PC using the Ethernet connection, it will be
necessary to alter the PC’s Ethernet adapter configuration to operate correctly with the
NextMove e100.

You cannot connect an ordinary office PC to the NextMove e100 without first altering
the PC’s Ethernet adapter configuration. However, if you have installed a second
Ethernet adapter dedicated for use with the NextMove e100, then this adapter’s
configuration can be altered without affecting the PC’s office Ethernet connection. If
you are unsure about making changes to your PC’s Ethernet adapter configuration,
or are prevented by user permission levels, ask your I.T. administrator to assist you.

Ensure that the NextMove e100 is not set to node ID 240 (hex F0).

The following explanation assumes the PC is connected directly to the NextMove e100, and not
across an intermediate Ethernet network. If you wish to attempt the connection through an
intermediate Ethernet network, then the network administrator must be consulted to ensure that
the necessary IP addresses will be allowed and are not already allocated on the network. The
NextMove e100 has a fixed IP address of the format 192.168.100.xxx. The last number, xxx,is

5. On the General tab, choose the ‘Use the following IP address’ option.

6. In the IP address box, enter the IP address 192.168.100.241. This is the IP address that will
be assigned to the Ethernet adapter. The value 241 is deliberately chosen as it is outside the
range that can be used by NextMove e100, so avoiding possible conflicts.

7. In the Subnet mask box, enter 255.255.255.0 and click OK.
Click OK to close the Local Area Connection Properties dialog.

8. On the Windows Start menu, select Command Prompt (often found under Accessories).

9. In the Command Prompt window, type PING 192.168.100.16, where the final value (16 in this
example) is the value selected by the NextMove e100’s node ID selector switches. In this
example, the NextMove e100’s switches would be set to HI=1 LO=0, which represents
hexadecimal 10, equivalent to decimal 16 (see section 4.4.2 for a list of hexadecimal /
decimal equivalents). A reply message should be returned.

10. It should now be possible to run Mint WorkBench and connect to the NextMove e100 using
the Ethernet / TCP/IP connection.

The Mint Machine Center (MMC) provides an overview of the controller network currently
accessible by the PC. The MMC contains a controller pane on the left, and an information pane
on the right. In the controller pane select the Host item, then in the information pane click Scan.
This causes MMC to scan for all connected controllers. Clicking once on a controller’s name
causes various options to be displayed in the information pane. Double-clicking on a controller’s
name launches an instance of Mint WorkBench that is automatically connected to the controller.

Application View allows the layout and organization of controllers in your machine to be modelled
and described on screen. Controllers can be dragged onto the Application View icon, and
renamed to give a more meaningful description, for example “Conveyor 1, Packaging Controller”.
Drives that are controlled by the NextMove e100 can be dragged onto the NextMove e100 icon
itself, creating a visible representation of the machine. A text description for the system and
associated files can be added, and the resulting layout saved as an “MMC Workspace”. When
you next need to administer the system, simply loading the workspace automatically connects to
all the required controllers. See the Mint help file for full details of MMC.

as ‘redirection’, and simplifies configuration of multiple controllers on an Ethernet / EPL network.

For the following procedure, it is essential that the NextMove e100’s node ID selector switches
are not set to F0. Although F0 is the correct node ID to make the NextMove e100 an EPL manager
node, the remote nodes have not yet been configured for EPL operation so will be ignored if the
NextMove e100 is operating as a manager node. In this example, communications will use
standard Ethernet, not EPL.

5.5 Conf iguring axes

The NextMove e100 is capable of controlling its own 4 stepper and 3 servo axes, plus further
‘remote’ axes over ETHERNET Powerlink (EPL). Each axis must be assigned a unique axis
number. The axis number is used throughout Mint WorkBench and the NextMove e100’s Mint
programs to identify a particular axis. This section describes how to configure each type of axis.

5.5.1 Local axes, remote axes and profilers

The NextMove e100 is capable of simultaneously ‘profiling’ up to 16 axes. A profiler is a
calculator used by the NextMove e100 to constantly update the required axis position during a
move’s progress. Axes that require a profiler include each of the 7 local axes, and each manager
node profiled remote axis (see 5.5.1.2 below). The profilers can be used to control independent
axes or to coordinate synchronized motion on up to 16 axes. For example, the NextMove e100
could profile its 7 local axes plus 9 independent manager node profiled remote axes, 4 groups of
4 synchronized axes, or any other combination. If none of the local axes are required, all 16
profilers could be used for remote manager node profiled remote axes.

5.5.1.1 Local axes

The NextMove e100 has 7 ‘local’ axes, each of which requires one profiler (if in use). The local
axes are the 4 stepper axes and 3 servo axes for which electrical connections are provided on
the NextMove e100’s edge connectors (STEP & DIR for stepper axes, Demand and ENC for
servo axes).

5.5.1.2 Remote axes

In addition to the 7 local axes, the NextMove e100 can also control several ‘remote’ axes.
Remote axes are drive amplifiers, such as MicroFlex e100, connected to the NextMove e100
over the EPL connection. There are three ways for the NextMove e100 (the manager node) to
control a remote axis (a controlled node):

H NextMove e100 can profile moves on behalf of the drive, sending continuously updated

incremental demands to the drive (‘manager node profiled’). Each remote axis of this type
consumes one profiler on the NextMove e100.

H NextMove e100 can send a single demand to the drive, and then allow the drive to profile

themoveitself(‘controlled node profiled’). After sending the demand the NextMove e100
takes no further part in controlling the move, so this type of remote axis does not consume
aprofilerontheNextMovee100.

H NextMove e100 can simply monitor the feedback from the drive, sending no demand

signals. This type of remote axis does not consume a profiler on the NextMove e100.

When controlling a remote axis, the NextMove e100 controller sends demand signals and/or
receives position information from the e100 drives over the EPL network. However, since the
e100 system uses intelligent positioning drives, the controller / drive combination does not form
a traditional feedback system. Instead, the position, speed and torque loops are closed locally by
the e100 drive for higher performance. Since the e100 drive / motor combination can be
autotuned, setup is much simpler than traditional systems.

5.5.2 Configuring remote axes

When configuring a remote axis on the NextMove e100, there is no requirement to determine the
type of axis, for example servo or stepper. Basic configuration requires only a node ID and an
axis number to be selected. In Mint WorkBench, the System Configuration Wizard is used to
assign the node IDs and axis numbers.

1. In the Toolbox, click the System
Configuration icon.

2. On the EPL Devices page, click

Add Device... .

3. In the central drop down box, select the
type of EPL device, for example
MicroFlex e100.

At the top of the window, select the node ID
of the EPL device. The node ID allows the
NextMove e100 to uniquely identify the
EPL device on the network.

Click OK.

The Resource Mapping window is displayed.

4. Click on the Axis 0 entry and click Map...

The Axis resource mapping window is
displayed.

www.baldormotion.com

Operation 5-15MN1941

5. In the Map to manager resource drop down
box, select one of the available axis
numbers and click OK. This is the axis
number that NextMove e100 will use to
reference the EPL device’s axis hardware.

The three radio button options refer to the
way the remote axis will be controlled - see
section 5.5.1.

In this example, the remote axis has been
assigned axis number 5. This means that when a Mint program running on the
NextMove e100 contains a statement such as MOVER(5)=20,theNextMovee100 will send
a demand to the remote axis (5)tomove20 units.

6. Click Close in the Resource Mapping
window. The EPL device is now listed in
the EPL Devices page.

Note: As shown in the preceding example, the EPL device’s assigned axis number (5)

and node ID (8) do not have to be the same. However, in small networks it may be
beneficial to assign the same node ID and axis number to simplify identification of
a particular node / axis.

examples of Mint basic code that can perform the network configuration at startup.

5.5.3 Configuring local axes

A local axis can be configured as either a servo, stepper or virtual axis. The factory preset
configuration sets all axes as unassigned (off), so it is necessary to configure an axis as either
stepper, servo or virtual before it can be used. The number of servo and stepper hardware
channels defines how many servo and stepper axes may be configured. The Control Rate
defines the accuracy with which moves on the axis will be performed. In the following example,
Mint WorkBench’s System Configuration Wizard will be used to configure the local axes:

1. In the Toolbox, click the System
Configuration icon to start the System
Configuration Wizard.

2. Click Next > to go to the (local) Axis Config
page.

3. On the Axis Config page, click Add Local
Axis... to display the Configure Local Axis
window.

4. In the Configure Local Axis window, select
one of the available axis numbers. This is
the axis number that will be assigned to the
local axis.

To create a servo axis:
Select the Servo radio button. In the Servo
frame, choose which encoder input(s) will
be used as the feedback input(s), and
which DAC output (Demandx output) will
be used for the axis.

To create a stepper axis:
Select the Stepper radio button. In the
Stepper frame, choose which pulse and
direction outputs (STEPx and DIRx
outputs) will be used for the axis.

To create a virtual axis:
Select the Virtual radio button. Setting an
axis to Virtual means that it can be used to
simulate motion within the controller, but
uses no physical outputs.

5. Click OK to close the Configure Local Axis
window. The axis is now listed in the Axis
Config page.

Click Next > to continue to the end of the
System Configuration Wizard, where the
configuration will be downloaded and
stored on the NextMove e100.

5.5.4 Selecting a scale

Mint defines all positional and speed related motion keywords in terms of encoder quadrature
counts (for servo motors) or steps for stepper motors. The number of quadrature counts (or
steps) is divided by the SCALEFACTOR allowing you to use units more suitable for your
application. The unit defined by setting a value for SCALEFACTOR is called the user unit (uu).

Consider a servo motor with a 1000 line encoder. This provides 4000 quadrature counts for each
revolution. If SCALEFACTOR is not set, a Mint command that involves distance, speed, or
acceleration may need to use a large number to specify a significant move. For example
MOVER(0)=16000 (Move Relative) would rotate the motor by 16000 quadrature counts - only
four revolutions. By setting a SCALEFACTOR of 4000, the user unit becomes revolutions. The
more understandable command MOVER(0)=4 could now be used to move the motor four
revolutions.

The same concept applies to stepper motors, where the scale can be set according to the
number of steps per revolution. Typically, this would be 200 for a motor with a 1.8° step angle, or
400 if driven in half step mode. By setting a SCALEFACTOR of 200 (or 400 if driven in half step
mode), the user unit becomes revolutions. In applications involving linear motion a suitable value
for SCALEFACTOR would allow commands to express values in linear distance, for example
millimeters, inches or feet.

When setting a SCALEFACTOR for a remote axis, the value is not sent to the remote axis. The
scale factor operates for commands and programs running on the NextMove e100, and should
be appropriate for the remote axis’ motor feedback device. The actual positional data transmitted
between the NextMove e100 and the remote axis is converted into ‘raw’ encoder counts. This
means that no matter what SCALEFACTOR has been set on the remote axis (if at all), positional
commands sent by the NextMove e100 are always received and interpreted correctly by the
remote axis.

1. In the Toolbox, click the Parameters icon.

2. In the parameters tree, scroll to the entry
for the chosen axis. This is found in the
Axis/Channel/Bank folder, under the Axis
sub heading.

3. The adjacent table will list the parameters
for the chosen axis.

Scroll to the entry for ScaleFactor.

www.baldormotion.com

5-18 Operation MN1941

Click in the Active column and enter a value for the scale factor. This immediately sets
the scaling factor for the selected axis, which will remain in the NextMove e100 until
another scale is defined or power is removed. A yellow ‘C’ icon will appear to the left of
the ScaleFactor entry to indicate that the value has been changed. Other parameters that
depend on the scale factor may also change automatically to maintain their relative value;
these will also be indicated by a yellow ‘C’ icon. See the Mint help file for full details of the
Parameters tool.

Note: The parameter list also contains entries for PosScaleFactor, VelScaleFactor and

AccelScaleFactor. These parameters are provided to comply with the CANopen

DS402 Device Profile for Drives and Motion Control, which specifies separate
scaling for position, velocity and acceleration. Each can be set to different values so
that, for example, position could be specified in mm, velocity in m/s

2

and
acceleration in g. However, in most cases all scaling will be required to use the
same type of unit, for example meters for position, m/s for velocity and m/s

2

for
acceleration. For this reason, setting the general purpose ScaleFactor parameter
will automatically set PosScaleFactor, VelScaleFactor and AccelScaleFactor to the
same values. See the Mint help file for further details.

5.5.5 Setting the drive enable output (optional)

Note: In many applications, a drive amplifier will have its drive enable input activated by

other circuitry (often including an emergency stop switch) so a physical drive
enable signal from the NextMove e100 is not required.

A drive enable output allows NextMove e100 to enable the external drive amplifier to allow
motion, or disable it in the event of an error. Each axis can be configured with its own drive enable
output, or can share an output with other axes. If an output is shared, an error on any of the axes
sharing the output will cause all of them to be disabled. The drive enable output can be either the
relay or a digital output.

For a remote axis (e.g. MicroFlex e100), a physical drive enable connection from the
NextMove e100 may not be required. The remote axis’ drive enable input can be wired to
external safety stop circuits to provide a fail-safe method for disabling the drive, while in normal
operation commands over the EPL network can be used to enable/disable the drive.

1. In the Toolbox, click the Digital I/O icon.

2. At the bottom of the Digital I/O screen, click

This section describes the method for testing and tuning a local servo axis. The drive amplifier
must already have been tuned for basic current or velocity control of the motor. See section 5.5.3
for details about creating a servo axis.

5.7.1 Testing the demand output

This section tests the operation and direction of the demand output for axis 0. The example
assumes that axis 0 has already been configured as a servo axis, using the default hardware
channel 0 (see section 5.5.3). It is recommended that the motor is disconnected from the load for
this test.

1. Check that the Drive enable button is
pressed (down).

2. In the Toolbox, click the Edit & Debug icon.

3. Click in the Command window.

4. Type:

TORQUEREF(0)=5

where 0 is the axis to be tested. In this
example, this should cause a demand of +5%
of maximum output (0.5 V) to be produced at
the DEMAND0 output (connector X13, pin 1).
In Mint WorkBench, look at the Spy window
located on the right of the screen. In the Axis selection box at the top, select Axis 0.

The Spy window’s Command display should show 5 percent (approximately). If there seems
to be no demand output, check the electrical connections to X13.

The Spy window’s Velocity display should show a positive value. If the value is negative check
that the DEMAND0 output, and the Encoder0 A and B channels, have been wired correctly.
If necessary, the ENCODERMODEkeyword can be used toswap the encoder Aand B channels,
thus reversing the encoder count - see the Mint help file.

See section 4.2.2 for details of the demand outputs.

www.baldormotion.com

5-24 Operation MN1941

5. To repeat the tests for negative (reverse) demands, type:

TORQUEREF(0)=-5

This should cause a demand of -5% of maximum output (-0.5 V) to be produced at the
DEMAND0 output. Correspondingly, the Spy window’s Velocity display should show a
negative value.

6. To remove the demand and stop the test, type:

STOP(0)

This should cause the demand produced at
the DEMAND0 output to become 0 V.

If it is necessary for the motor to turn in the opposite direction for a positive demand, then the
DACMODE and ENCODERMODE keywords should be used. The DACMODE keyword is used to
invert the demand output voltage. The ENCODERMODE keyword must then also be used to
reverse the incoming feedback signal, to correspond with the inverted demand output. Note that
if ENCODERMODE had already been used to compensate for a reversed encoder count (as
described in step 4. above), it will be necessary to change it back to its original setting to
correspond with the inverted demand output set using DACMODE. Whichever keywords are used,
for the control system to operate correctly, a positive demand must result in a positive change in
position and a negative demand must result in a negative change in position.

See the Mint help file for details of each keyword.

5.7.2 An introduction to closed loop control

This section describes the basic principles of closed loop control. If you are familiar with closed
loop control go straight to section 5.8.1.

When there is a requirement to move an axis, the NextMove e100 control software translates this
into a demand output voltage (or just a numerical value over EPL). This is used to control the
drive amplifier which powers the motor. An encoder or resolver on the motor is used to measure
the motor’s position. At specified intervals* the NextMove e100 compares the demanded and
measured positions. It then calculates the demand needed to minimize the difference between
them, known as the following error.

This system of constant measurement and correction is known as closed loop control.
[For the analogy, imagine you are in your car waiting at an intersection. You are going to go

straight on when the lights change, just like the car standing next to you which is called Demand.
You’re not going to race Demand though - your job as the controller (NextMove e100) is to stay
exactly level with Demand, looking out of the window to measure your position].

The main term that the NextMove e100 uses to correct the error is called Proportional gain
(KPROP). A very simple proportional controller would simply multiply the amount of error by the
Proportional gain and apply the result to the motor [the further Demand gets ahead or behind you,
the more you press or release the gas pedal ].

If the Proportional gain is set too high overshoot will occur, resulting in the motor vibrating back
and forth around the desired position before it settles [you press the gas pedal so hard you go

right past Demand. To try and stay level you ease off the gas, but end up falling behind a little. You
keep repeating this and after a few tries you end up level with Demand, traveling at a steady
speed. This is what you wanted to do but it has taken you a long time].
If the Proportional gain is increased still further, the system becomes unstable [you keep
pressing and then letting off the gas pedal so hard you never travel at a steady speed ].

To reduce the onset of instability, a term called Velocity Feedback gain (KVEL) is used. This
resists rapid movement of the motor and allows the Proportional gain to be set higher before
vibration starts. Another term called Derivative gain (KDERIV) can also be used to give a similar
effect.

With Proportional gain and Velocity Feedback gain (or Derivative gain) it is possible for a motor
to come to a stop with a small following error [Demand stopped so you stopped too, but not quite
level ]. The NextMove e100 tries to correct the error, but because the error is so small the
amount of torque demanded might not be enough to overcome friction.

This problem is overcome by using a term called Integral gain (KINT). This sums the error over
time, so that the motor torque is gradually increased until the positional error is reduced to zero
[like a person gradually pushing harder and harder on your car until they’ve pushed it level with
Demand].

However, if there is large load on the motor (it is supporting a heavy suspended weight for
example), it is possible for the output to increase to 100% demand. This effect can be limited
using the KINTLIMIT keyword which limits the effect of KINT to a given percentage of the
demand output. Another keyword called KINTMODE can even turn off integral action when it’s not
needed.

* The sampling interval can be changed using the CONTROLRATE keyword - see the Mint help
file.

The remaining gain terms are Velocity Feed forward (KVELFF) and Acceleration Feed
forward (KACCEL) described below.

In summary, the following rules can be used as a guide:

H KPROP: Increasing KPROP will speed up the response and reduce the effect of

disturbances and load variations. The side effect of increasing KPROP is that it also
increases the overshoot, and if set too high it will cause the system to become unstable. The
aim is to set the Proportional gain as high as possible without getting overshoot, instability or
hunting on an encoder edge when stationary (the motor will buzz).

H KVEL: This gain has a damping effect on the whole response, and can be increased to

reduce any overshoot. If KVEL becomes too large it will amplify any noise on the velocity
measurement and introduce oscillations.

H KINT: This gain has a de-stabilizing effect, but a small amount can be used to reduce any

steady state errors. By default, KINTMODE is always on (mode 1).

H KINTLIMIT: The integration limit determines the maximum value of the effect of integral

action. This is specified as a percentage of the full scale demand.

H KDERIV: This gain has a damping effect dependent on the rate of change of error, and so is

particularly useful for removing overshoot.

H KVELFF: This is a feed forward term and as such has a different effect on the servo system

than the previous gains. KVELFF is outside the closed loop and therefore does not have an
effect on system stability. This gain allows a faster response to demand speed changes with
lower following errors, for example you would increase KVELFF to reduce the following error
during the slew section of a trapezoidal move. The trapezoidal test move can be used to
fine-tune this gain. This term is especially useful with velocity controlled servos

H KACCEL: This term is designed to reduce velocity overshoots on high acceleration moves.

5.8 Lo cal servo axis - tuning for current control

5.8.1 Selecting servo loop gains

All servo loop parameters default to zero, meaning that the demand output will be zero at power
up. Most drive amplifiers can be set to current (torque) control mode or velocity control mode;
check that the drive amplifier will operate in the correct mode. The procedure for setting system
gains differs slightly for each. To tune an axis for velocity control, go straight to section 5.9. It is
recommended that the system is initially tested and tuned with the motor shaft disconnected from
other machinery. Confirm that the encoder feedback signals from the motor or drive amplifier
have been connected, and that a positive demand causes a positive feedback signal.

Note: The method explained in this section should allow you to gain good control of the

motor, but will not necessarily provide the optimum response without further
fine-tuning. Unavoidably, this requires a good understanding of the effect of the gain
terms.

1. In the Toolbox, click the Fine-tuning icon.

The Fine-tuning window is displayed at the
right of the screen. The main area of the Mint
WorkBench window displays the Capture
window. When tuning tests are performed,
this will display a graph representing the
response.

2. In the Fine-tuning window, click in the Axis
selection box at the top and select Axis 0
(assuming axis 0 has already been
configured as a servo axis - see section

5.5.3).

Click in the KDERIV box and enter a starting
value of 1.

Click Apply and then turn the motor shaft by
hand. Repeat this process, slowly increasing
the value of KDERIV until you begin to feel
some resistance in the motor shaft. The
exact value of KDERIV is not critical at this
stage.

www.baldormotion.com

Operation 5-29MN1941

3. Click in the KPROP box and enter a value
that is approximately one quarter of the value
of KDERIV . If the motor begins to vibrate,
decrease the value of KPROP or increase
the value of KDERIV until the vibration stops.
Small changes may be all that is necessary.

4. In the Move Type drop down box, check that
the move type is set to Step.

5. Click in the Distance box and enter a distance
for the step move. It is recommended to set
a value that will cause the motor to turn a
short distance, for example one revolution.

Note: The distance depends on the scale set in section 5.5.4.

If you set a scale so that units could be expressed in revolutions (or other unit of your
choice), then those are the units that will be used here. If you did not set a scale, the
amount you enter will be in encoder counts.

6. Click in the Duration box and enter a duration
for the move, in seconds. This should be a
short duration, for example 0.15 seconds.

7. Click Go.

The NextMove e100 will perform the move and the motor will turn. As the soon as the move
is completed, Mint WorkBench will upload captured data from the NextMove e100. The data
will then be displayed in the Capture window as a graph.

5.8.2 Underdamped response

If the graph shows that the response is underdamped (it overshoots the demand, as shown in
Figure 38) then the value for KDERIV should be increased to add extra damping to the move. If
the overshoot is excessive or oscillation has occurred, it may be necessary to reduce the value
of KPROP.

5.8.3 Overdamped response

If the graph shows that the response is overdamped (it reaches the demand too slowly, as shown
in Figure 39) then the value for KDERIV should be decreased to reduce the damping of the move.
If the overdamping is excessive, it may be necessary to increase the value of KPROP.

5.9 Lo cal servo axis - tuning for velocity co n t rol

Drive amplifiers designed for velocity control incorporate their own velocity feedback term to
provide system damping. For this reason, KDERIV (and KVEL) can often be set to zero.

Correct setting of the velocity feed forward gain KVELFF is important to get the optimum
response from the system. The velocity feed forward term takes the instantaneous velocity
demand from the profile generator and adds this to the output block (see Figure 37).
KVELFF is outside the closed loop and therefore does not have an effect on system stability.
This means that the term can be increased to maximum without causing the motor to oscillate,
provided that other terms are setup correctly.

When setup correctly, KVELFF will cause the motor to move at the speed demanded by the
profile generator. This is true without the other terms in the closed loop doing anything except
compensating for small errors in the position of the motor. This gives faster response to changes
in demand speed, with reduced following error.

Before proceeding, confirm that the encoder feedback signals from the motor or drive amplifier
have been connected, and that a positive demand causes a positive feedback signal.

5.9.1 Calculating KVELFF

To calculate the correct value for KVELFF, you will need to know:

H The speed, in revolutions per minute, produced by the motor when a maximum demand

(+10 V) is applied to the drive amplifier.

H The axis’ position loop update rate (the Control Rate setting selected in the Config Local Axis

dialog - see section 5.5.3).

H The resolution of the encoder input.

The servo loop formula uses speed values expressed in quadrature counts per servo loop.To
calculate this figure:

1. First, divide the speed of the motor, in revolutions per minute, by 60 to give the number of
revolutions per second. For example, if the motor speed is 3000 rpm when a maximum
demand (+10 V) is applied to the drive amplifier:

Revolutions per second = 3000 / 60

=

50

2. Next, calculate how many revolutions will occur during one servo loop. The factory preset
position loop update rate is 1 kHz (0.001 seconds), so:

Revolutions per servo loop = 50 x 0.001 seconds

=

0.05

3. Now calculate how many quadrature encoder counts there are per revolution. The
NextMove e100 counts both edges of both pulse trains (CHA and CHB) coming from the
encoder, so for every encoder line there are 4 ‘quadrature counts’. With a 1000 line encoder:

Quadrature counts per revolution = 1000 x 4

=

4000

4. Finally, calculate how many quadrature counts there are per servo loop:

Quadrature counts per servo loop = 4000 x 0.05

=

200

www.baldormotion.com

5-34 Operation MN1941

The analog demand output is controlled by a 12-bit DAC, which can create output voltages in the
range -10 V to +10 V. This means a maximum output of +10 V corresponds to a DAC value of

2048. The value of KVELFF is calculated by dividing 2048 by the number of quadrature counts
per servo loop, so:

KVELFF = 2048 / 200

=

10.24

5. Click in the KVELFF box and enter the value.

The calculated value should give zero
following error at constant velocity. Using
values greater than the calculated value will
cause the controller to have a following error
ahead of the desired position. Using values
less than the calculated value will cause the
controller to have following error behind the
desired position.

6. In the Move Type drop down box, check that
the move type is set to Trapezoid.

7. Click in the Distance box and enter a distance
for the step move. It is recommended to set
a value that will cause the motor to make a
few revolutions, for example 10.

Note: The distance depends on the scale set in section 5.5.4. If you set a scale so that

units could be expressed in revolutions (or other unit of your choice), then those are
the units that will be used here. If you did not set a scale, the amount you enter will
be in encoder counts.

8. Click Go.

The NextMove e100 will perform the move and the motor will turn. As the soon as the move
is completed, Mint WorkBench will upload captured data from the NextMove e100. The data
will then be displayed in the Capture window as a graph.

5.10 Local servo axis - eliminating steady-state errors

In systems where precise and accurate positioning is required, it is often necessary to position
within one encoder count. Proportional gain, KPROP, is not normally able to achieve this
because a very small following error will only produce a small demand for the drive amplifier
which may not be enough to overcome mechanical friction (this is particularly true in current
controlled systems). This error can be overcome by applying integral gain. The integral gain,
KINT, works by accumulating following error over time to produce a demand sufficient to move
the motor into the required position with zero following error. KINT can therefore overcome errors
caused by gravitational effects such as vertically moving linear axes. With current controlled
drive amplifiers a non-zero demand output is required to hold the load in the correct position, to
achieve zero following error.

Care is required when setting KINT since a high value will cause instability during moves.
A typical value for KINT would be 0.1. The effect of KINT should also be limited by setting the
integration limit, KINTLIMIT, to the smallest possible value that is sufficient to overcome friction
or static loads, for example 5. This will limit the contribution of the integral term to 5% of the full
demand output range.

1. Click in the KINT box and enter a small
starting value, for example 0.1.

2. Click in the KINTLIMIT box and enter a value
of 5.

With NextMove e100, the action of KINT and KINTLIMIT can be set to operate in various
modes:

H Never - the KINT term is never applied

H Always - the KINT term is always applied

H Smart - the KINT term is only applied when the demand speed is zero or constant.

H Steady State - the KINT term is only applied when the demand speed is zero.

This function can be selected using the KINTMODE drop down box.

number of Tx and/or Rx errors, greater than the off threshold of 255. At this point the node will
have switched itself to a state whereby it cannot influence the bus. Check:

H 12-24 V is being applied between pin 9 (+24 V) and pin 6 or 3 (0 V) of the CAN connector, to

power the opto-isolators.

H There is at least one other CANopen node in the network.

H The network is terminated only at the ends, not at intermediate nodes.

H All nodes on the network are running at the same baud rate.

H All nodes have been assigned a unique node ID.

H The integrity of the CAN cables.

To recover from the ‘off’ state, the source of the errors must be removed and bus then reset. This
can be done using the Mint BUSRESET keyword, or by resetting the NextMove e100.

Troubleshooting 6-7MN1941

The Manager node cannot scan/recognize a node on the network using the Mint
NODESCAN keyword:

Assuming that the network is working correctly (see previous symptoms) and the bus is in an
‘Operational’ state, check:

H Only nodes that conform to DS401, DS403 and other Baldor CANopen nodes are

recognized by the Mint NODESCAN keyword. Other types of node will be identified with a type
“unknown” (255) when using the Mint NODETYPE keyword.

H Check that the node in question has been assigned a unique node ID.

H The node must support the node guarding process. NextMove e100 does not support the

Heartbeat process.

H Try power-cycling the node in question.

If the node in question does not conform to DS401 or DS403 and is not a Baldor CANopen node,
communication is still possible using a set of general purpose Mint keywords. See the Mint help
file for further details.

The node has been successfully scanned / recognized by the Manager node, but
communication is still not possible:

For communication to be allowed, a connection must be made to a node after it has been
scanned:

H Baldor controller nodes are automatically connected to after being scanned.

H Nodes that conform to DS401, DS403 must have the connections made manually using the

Mint CONNECT keyword.

If a connection attempt using CONNECT fails then it may be because the node being connected
to does not support an object which needs to be accessed in order to setup the connection.
