Section 1 General Information Introduction The Baldor controls represent the latest technology in microprocessor based motor controls. In addition to the user programmable parameters available in every control, many different expansion boards are available from Baldor to further customize the control to most any application. Expansion boards are categorized by compatibility into two groups: Group 1 and Group 2, see Table 1-1. A board from either group may be used alone in a control.
Limited Warranty For a period of two (2) years from the date of original purchase, BALDOR will repair or replace without charge controls and accessories which our examination proves to be defective in material or workmanship. This warranty is valid if the unit has not been tampered with by unauthorized persons, misused, abused, or improperly installed and has been used in accordance with the instructions and/or ratings supplied.
Safety Notice This equipment contains voltages that may be as great as 1000 volts! Electrical shock can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment. This equipment may be connected to other machines that have rotating parts or parts that are driven by this equipment. Improper use can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment.
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power before you ensure that all grounding instructions have been followed. Electrical shock can cause serious or fatal injury. WARNING: Do not remove cover for at least five (5) minutes after AC power is disconnected to allow capacitors to discharge. Dangerous voltages are present inside the equipment. Electrical shock can cause serious or fatal injury.
Section 2 Expansion Board Description Introduction The Modbus Plus expansion board is a Group 2 expansion board. It allows a Series H control to communicate as a node on the Modbus Plus network. It has a DB9 connector to make connection to the network simple. Group 2 board Modbus Plus Expansion Board Catalog No. EXB015A01 A good resource document is the “Modicon Plus Network Planning and Installation Guide”.

LED Indicators Five LED’s are located on the Modbus Plus expansion board (see Figure 4-1 for their locations). D1 Modbus Plus Status LED D1 displays the operational status of the Modbus Plus Interface expansion board (EXB). When power is first applied, the LED will pause, then flash slowly 8 times while it checks the network. If a valid Modbus Plus connection is established, D1 will flash continuously. Otherwise, it flash an error code as shown in Table 4-2.
Control Terminal Strip Connections For Serial Mode operation, the Input/Output terminal strip of the control (J1 of the Vector and DC controls and J4 of the Inverters) is wired as shown in Figure 4-2. Connect the Enable, Forward Enable Switch, Reverse Enable Switch, External Trip and Opto Common connections as shown. Note: All opto-isolated outputs and analog outputs remain active while operating in the Serial Mode.

Section 5 Register Map for Modbus Plus Configure Control Software for Modbus Plus Mode The Series H control operating mode must be set to Serial to use the Modbus Plus expansion board. There is no selection for Modbus Plus on the Level 1 Input block Operating mode parameter list. However, selecting Serial with the Modbus Plus expansion board installed will allow operation of the Modbus Plus board.

Data Exchange with the Modbus Plus Expansion Board This section describes the register interface used for data exchange with the Series H control. Motor drive parameters are mapped to Modbus Plus “Data/Holding” registers (4xxxx). Parameters can be read from or written to the Series H control by reading from or writing to the appropriate Modbus Plus registers.
For 15Hand 21H Inverter controls, use the following registers for communication. For all other H controls, use the Standard Series H Area Register Mapping.
