1. Introduction

The Metasys® N2 communication option for the GPD505 and GPD506/P5 allows these drives to be
integrated into a new or existing Metasys

This manual describes the steps necessary for hardware installation, network identification, and operation
of the interface. Refer to the appropriate Technical Manual for additional information regarding drive
operation and setup.

2. Hardware Installation

This section describes steps necessary to install the option card and configure the drive for its use. Since
this option is available pre-installed or in kit form, many of these steps may have been completed at the
factory. If already installed, users should still review these steps to become familiar with the procedure.

Refer to Figure 1 for the physical location of switches, LEDs and connectors.

CAUTION: Make sure that the input power to the drive is TURNED OFF and the CHARGE lamp

inside the unit is OFF before installing the option card.

Step 1. Remove the digital operator, applying pressure to the locking plate on its lower right side, as

illustrated in Figure 2. Lift the operator out by pulling forward.

Step 2. Remove the drive cover, applying pressure to the locking tabs on either side of the cover as

illustrated in Figure 3. With the locking tabs disengaged, pivot the cover out from the bottom.
Continue pivoting it until the top hinge disengages.

Step 3. Position the option card so that the 12-pin interface cable is to the left, as illustrated in Figure 4.

Carefully press the attached cable connector into connector 2CN until it is firmly seated.
Please note the orientation of the locking tab relative to the connector mounted on the control
board.

Step 4. Position the option board mounting holes directly over the four standoffs on the control board.

Carefully press the option board onto the standoffs until it is firmly seated.

2.2 Drive Set-up

The drive must be properly configured to communicate with the option card, as described below:

GPD505

Parameter

n106 n104 1 Address (01)
n107 n105 2 Baud Rate (9600)
n108 n106 0 Parity (None)

NOTE: Parameter n001 must be set to 3 to change these parameters. New settings will not take

affect until drive power is cycled.

If any of these settings are incorrect, “CALL” will blink on the digital operator, as will the RXD, TXD and
FAULT LEDs. This is an indication that the drive has not yet established communication with the option
card. Once the drive has properly exchanged messages with the option card, all blinking should stop.

2.3 Network Connection

Communication on the network is half-duplex, two-wire RS-485, with communication parameters fixed at
9600 baud, eight data bits, no parity and one start/stop bit. The connection medium is shielded twisted pair
cable.

Network connection is facilitated by a pluggable 4-way Phoenix-style connector, as illustrated in Figure 5.
Particular attention should be given to the polarity of the network connection. Proper communication
cannot be established with these terminals reversed.

2.3.1 Bus Terminating Resistor

A bus terminating resistor (120Ω) is available on each option board and can be applied to the bus by setting
the switches of S3 to their ON position.

In a multi-node system, only those nodes at the end of a bus segment should have terminating resistors.
Before applying a terminating resistor as described above, care should be taken to understand the physical
layout of the network and where other resistors might already be applied. An overloaded bus may not
function properly.

2.4 Network Addressing

A drive’s network address is assigned by selecting the proper setting for switch S1, as detailed in Table 1:

4.2.7 Terminal S1 Run/Stop Control

In certain applications, a normally closed system safety may be wired to the drive’s terminal S1. The basis
for this design is a hard-wired run command at terminal S1. If a safety is placed in series with this run
contact, the drive stops when the safety opens.

With this option card, the same functionality can be achieved with a network run command. It is enabled by
setting GPD505 parameter n039 to 19 or GPD506 parameter n040 to 21. With this feature enabled, a
network run command starts the drive only if the contact on S1 is closed. If the contact opens, the drive is
stopped and then restarted once the contact closes.

4.3.2 Current Rating – AI14

This analog input reports the current rating of the drive. This information is useful in matching a motor to the
drive and determining the settings for AO6 (Stall Prevention Level during Run), AO7 (Stall Prevention Level
during Accel), and AO12 (Motor Rated Current), all expressed in terms of the drive’s current rating.

4.3.3 Reading Other Parameters – AO21, AI15

Two objects are defined for reading any drive parameter:

AO21 - Specifies the parameter to be read.
AI15 - Reports the value of the specified parameter.

Refer to the appropriate Technical Manual for a detailed description of all parameters.

NOTE: The increment listed in the Technical Manual must be considered when interpreting a

reported value. For example, a read of GPD506 parameter n070 (GPD505 n066), DC
Injection Time at Stop, which reports 10 in AI15 is actually a setting of 1, since the
increment for this parameter is 0.1 seconds.

4.4 Cable Loss Behavior

This section describes the configurable cable loss feature of the option card. This feature offers a user
maximum flexibility in determining the drive’s response to a loss of communication.

After some interval without receipt of a message, the drive can be configured to respond in one of the
following manners:

• Continue at last speed

• Continue at preset speed

• Stop

• Fault (EF0)

Three points are used to select the desired type of behavior:

• AO19 – Cable Loss Timeout

• AO20 – Cable Loss Speed

• BO10 – Communication Fault Enable

The following table summarizes the settings for each type of behavior (X = don’t care):

Behavior Cable Loss Timeout

(AO19)

Continue at last speed 0 X X

Continue at preset speed Timeout Interval Preset Speed Off

Stop Running Timeout Interval 0 Off

Fault (EF0) Timeout Interval X On

Cable Loss Frequency

(AO20)

Fault Enable

(BO10)

Each behavior is described in additional detail below.

Notes

1. Communication must first be established and then lost for these features to function as described. If a
drive is powered-up without a cable connected or with the master controller offline, a timeout does not
occur.

2. For modes which describe the drive running after a timeout, a run command must have been issued
(BO1 = ‘On’) prior to loss of communications. For safety purposes, it will not automatically start from a
stopped condition. If a user requires the drive to start automatically, additional external wiring may be
added to accomplish this (consult factory).

3. Upon expiration of the timeout interval, the FAULT LED lights and remains lit until communication is
restored.

4.4.1 Continue Running at Last Speed

In this mode, Cable Loss Timeout (AO19) is set to 0, disabling the cable loss feature. The other 2 settings
(BO10, AO20) are ignored. If communication is lost, the drive simply maintains its last commanded state.

4.4.2 Continue Running at Preset Speed

In this mode, Cable Loss Timeout (AO19) is set to the desired interval and Cable Loss Speed (AO20) is set
to the desired preset speed. If the time between messages exceeds the timeout interval, the drive’s speed
command (AO1) is set to the Cable Loss Speed (AO20) and the drive continues running at this new speed.
Communication Fault Enable (BO10) must be set to ‘Off’.

TM4028 7/12/2001

21

4.4.3 Stop Running

In this mode, Cable Loss Timeout (AO19) is set to the desired interval and Cable Loss Speed (AO20) is set
to 0. If the time between messages exceeds the timeout interval, the drive’s speed command (AO1) is set
to 0 and the run command (BO1) is set to ‘Off’. Communication Fault Enable (BO10) must be set to ‘Off’.

4.4.4 Fault

In this mode, Cable Loss Timeout (AO19) is set to the desired interval and Communication Fault Enable
(BO10) is set to ‘On’. If the time between messages exceeds the timeout interval, an ‘EF0’ fault is declared
and the drive stops. Cable Loss Speed (AO20) is ignored.

5. Bypass Applications

For many applications, the drive is integrated into a bypass or engineered package. This type of package
typically features an enclosure with contactors which allow the user to run the motor from line power
(bypass mode) or from the drive (drive mode). This package also provides the flexibility for interfacing
normally closed safety interlocks (firestat, freezestat, vibration sensors, etc.) which stop the drive if the
contacts open.

5.1 Typical Parameter Settings

Because of the widespread use of this type of application, the following parameter set-up table is provided
to aid in the start-up of such a drive.

stored in the option card. If they differ, the functions will not complete and the ERROR LED
will be lit.

6.1 Save Parameters

This function saves the current parameters to the option card.
This feature may be particularly useful to users as a final step in their setup procedure. Once a drive has

been “fine-tuned” for a particular application, its unique setup can be saved for future use. A particular
setup may then be recalled when replacing a drive, copying to other drives, or restoring a setup that has
been altered.

To use this function, the following sequence should be observed:

1. Remove drive power.

2. Remove the network connection.

3. Select the desired function by setting switches S1 and S2 as described in Table 2.

4. Re-apply drive power.

5. Observe the RXD LED flashing. This occurs while the parameters are being read from the drive

and stops when this step is complete.

6. Observe the TXD LED flashing. This occurs while the parameters are being written to the option

card EEPROM and stops when this step is complete.

7. Upon successful completion of this function, the TXD LED remains on and all other LEDs should be

This function compares the current parameters to the values saved in the option card, displaying
differences on the digital operator.

With a unique drive setup already saved in the option card, this feature may be used to evaluate which
parameters have been changed since the setup was saved. This may be particularly useful in summarizing
parameter changes during a troubleshooting process or determining what changes have been made since
a drive’s initial installation.

To use this function, the following sequence should be observed:

1. Remove drive power.

2. Remove the network connection.

3. Select the desired function by setting switches S1 and S2 as described in Table 2.

compared to the values stored in the option card EEPROM and stops when this step is complete.

7. Upon successful completion of this function, the TXD LED remains on and all other LEDs should be

off if no differences exist. If there are any differences, the ERROR LED will be flashing. Monitor

U-11 is used to display the data which is different. The parameter number is displayed first, as
‘1xxx’, where ‘xxx’ is the parameter number. The next value displayed is the value stored in the
option card EEPROM. These values can be recorded and compared to the current drive settings.
The list of differences is displayed repeatedly until power is removed.

8. Remove drive power.

9. Reset switches S1 and S2 to their usual settings.

7. Diagnostic LEDs

7.1 RXD

This LED is lit under the following conditions:

• While the drive is attempting to establish communication with the option card, the RXD, TXD, and
FAULT LEDs blink in unison and “CALL” blinks on the digital operator. If this condition occurs, repeat
the steps outlined in Section 2.2, Drive Set-up.

• During normal operation with the drive attached and configured on the network, this LED blinks anytime
the drive receives a message addressed to it. Its blinking under these conditions indicates a “healthy”
link between the drive and the network.

• During normal operation with the drive either unattached or unconfigured on the network, this LED
blinks while the option card is communication with the drive. Its blinking under these conditions
indicates a “healthy” link between the drive and the option card.

• During use of the parameter management functions, this LED blinks during the first phase of each
function and is off upon completion (See Section 6, Parameter Management Functions).

7.2 TXD

This LED is lit under the following conditions:

• While the drive is attempting to establish communication with the option card, the RXD, TXD, and
FAULT LEDs blink in unison and “CALL” blinks on the digital operator. If this condition occurs, repeat
the steps outlined in Section 2.2, Drive Set-up.

• During normal operation, this LED blinks anytime the drive is responding to a message from the
network. Its blinking indicates a “healthy” link between the drive and the network.

• During use of the parameter management functions, this LED blinks during the second phase of each
function and remains lit upon completion (See Section 6, Parameter Management Functions).

7.3 FAULT

This LED is lit under the following conditions:

• While the drive is attempting to establish communication with the option card, the RXD, TXD, and
FAULT LEDs blink in unison and “CALL” blinks on the digital operator. If this condition occurs, repeat
the steps outlined in Section 2.2, Drive Set-up.

• During normal operation, this LED is lit if a cable loss is detected (See Section 4.4,

TM4028 7/12/2001
