December 2000 Parameter Setup

• At each connector, check the continuity between pin 1 and the

MODBUS PLUS cable shield ground point on the heat sink. Direct

continuity should not be present.

• Check for proper termination and insulation of individual drop twisted

pair shields.

If any check point fails, inspect the cable and all connections for damage

or miswiring, and correct the condition.

PARAMETER SETUP

Configuring the Communication Parameters

Initial Power-Up

When the MODBUS PLUS card is initially powered up, it is automatically

recognized by the drive controller. It provides access to the

8—Communication menu on the operator keypad.

Configuration

Select the 8—Communication menu (see Table 8 on page 36) to access

the option card configuration parameters. Using the keypad, enter “8 SL”

(Serial Link, Communication). The first parameter is the address of the

drive controller on the network. Because this parameter is physically

configured on the card with switches 1 to 6 (see “Setting the Drive

Controller Address” on page 12), it can only be read from the keypad.

NOTE: The communication parameters can only be modified with the

motor stopped.
