MOTOR ENCODER CABLE:

The motor encoder cable is connected to plug-in terminal strip TB1:A on the DFS-1 PC board. A shielded cable must be used for the motor encoder cable. The recommended cable is a 9-conductor shielded cable (Belden Cable part # 9539 or equiva- lent). The shield should be connected at the drive end to the shield terminal (TB1:A1) and to terminal 10 (if there is one) at the motor terminal strip and if not (as on motors built prior to April 1992), the shield should be cut off at the motor end and taped up.

The DFS-1 PC Board contains all of the func- tions necessary to operate the Brushless DC motor control according to the inputs connected to its terminals and the programmed information in memory. The DFS-1 board takes care of all speed, torque, and control functions. It takes speed informa- tion from the encoder, environmental information and current (load) information from the power output circuits of the drive, and compares all that informa- tion to the input conditions and programmed param- eters. It processes this information and turns the power transistors on and off according to the needs of the system.

The DFS-1 is delivered with an installed set of default parameters which will allow it to operate with a standard set of connections (as illustrated in Figure 3) of the types used with standard motor controls.

However, these standard connections will not be in the same physical positions as they are in the standard control, and the default setting will not take care of any optional modes of operation.

There are three plug-in terminal strips on the bottom of the DFS-1 PC board labelled in sections from left to right: TB1, TB2, and TB3. Though the three sections look like two rows of strips, there is a small separator between each of the sections. Each of the sections has an upper row (A) and a lower row

(B). The B row is closest to the PC board. The terminals are numbered consecutively from left to right on each level.

ANALOG INPUTS:

There are two analog input ports to the DFS-1 on TB1:B. When used as a voltage input, both of the analog inputs are a differential type of input with a minimum input impedance of 200 Kohms. When using one of the analog inputs for a voltage input, the input common at terminal 1 on TB1:B should be used for shields.

When using an analog input as a milliamp input, the (-) side of the input (terminal 4 for Analog Input #1 or terminal 6 for Analog Input #2) should be connected to the common of the milliamp current source. The milliamp source should be connected to the (+) input (terminal 3 for Analog Input #1 or terminal 5 for Analog Input #2).
