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 Resolver to Digital Interface Expansion Board Catalog No. EXB009A01 Group 1 Expansion Board The Resolver to Digital Interface expansion board provides closed loop operation for the Baldor Series 18H, 19H, 20H and 22H controls. The Resolver to Digital Interface can also be used for PID control. Note: When a Resolver to Digital Interface is used in a process control application, an encoder should be used to provide velocity feedback to the control.

3-12 Installation
Section 4 Hardware Setup Important: If the Resolver to Digital expansion board is installed in a Vector control that has a feedback module installed, the feedback module must be removed to prevent interference with the expansion board. Figure 4-1 shows how to identify the feedback module on the DSP Main Control Board. The main control board is where the keypad plugs in.
If your Vector control does not look like the one pictured in Figure 4-1, do not perform the feedback module removal procedure. Instead, continue onto page 4-3. Feedback Module Removal Procedure If your Vector control looks like the one pictured in Figure 4-1, perform the following procedure: The resolver feedback module must be removed from the main control board to change the JP1 position. Use the following procedure. 1. 2. Be sure drive operation is terminated and secured.
Connections WARNING: High voltage is present on the Resolver to Digital expansion board. Do not touch any circuit board, power device or electrical connection before you first ensure that power has been disconnected and there is no high voltage present from this equipment or other equipment to which it is connected. Electrical shock can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment. Procedure: (Refer to Figure 4-1 and FIgure 4-2.

Section 5 Software Setup Configure Control Software After the Resolver to Digital Interface board has been installed and the DIP switches are correctly set, the control software must be configured. Series 18H and 22H Vector Controls Note: When the Resolver to Digital Interface board is installed, the encoder inputs to the control are automatically disabled (J1 pins 23 to 30). The value of the Level 2, MOTOR DATA Block, “Resolver Speed” parameter (P2509) must be set to the correct speed value. Procedure: 1.
