2.0SPECIFICATIONS

POWER SUPPLIES

+24VDC • Available at TB2:A14, and TB2:B1.

•The combination is fused at 250 milliamps (mA). The fuse is self-healing.

•The opening of the fuse alerts the micro- processor.

•These supplies should only be used for push-buttons, relays, PLC outputs, etc. which interface directly with the DFS-1. They should not be used as general pur- pose supplies.

+10VDC • Reference supply available at TB1:B2. This output is rated at 100mA. This out- put is current limited and thermally pro- tected.

-10VDC • Reference supply available at TB1:B7. This output is rated at 100mA, current limited and thermally protected.

+5VDC • Supply for motor encoder available at TB1:A9. This supply is fused at 100mA with a self-healing fuse. When the fuse opens, it alerts the microprocessor.

THIS SUPPLY IS FOR THE MOTOR ENCODER ONLY!

ANALOG INPUTS

1.0There are two analog inputs on TB1:B. (see section 1.2, page 4)

2.0Each input may be set up in one of several modes.

3.0Pre-programmed modes are:

3.1General purpose Input

3.2Speed Reference Input

3.3Trim (dancer or load cell) Input

3.4External Motoring Torque Limit

3.5External Regenerative Torque Limit

3.6Horsepower Mode

4.0The mode of the input is set by parameter (#17 for Analog Input #1 and parameter #21 for Analog Input #2).

5.0Each of the two inputs may be set up one of six ways:

1.

-10

to +10

VDC

2.

0

to +10

VDC

3.

0

to 5

VDC

4.

1

to 5

VDC

5.

0

to 20

mADC

6.

4

to 20

mADC

6.0Setup is by parameter selection (#18 for Analog Input #1 and parameter #22 for Analog Input #2).

7.0Voltage inputs are a differential input connec- tion.

8.0Input impedance of each input in voltage input mode is 200 Kilohms minimum.

9.0Input impedance in milliamp input mode is 250 ohms.

Factory default setups are included so that the DFS-1 does not have to be programmed prior to its initial use. Factory defaults are only one of the many ways the DFS-1 can be set up.

Default setups are as follows:

General Purpose Input

ANALOG OUTPUTS

1.0There are two analog outputs on TB1:B.

2.0The analog outputs may be programmed for one of five modes:

2.1Disabled

2.2Motor Speed Output -10 to +10VDC

=0 to 100% (Actual Motor Speed) Default - Analog Output #1

2.3Motor Load Output -10 to +10VDC

=0 to 150%

Default - Analog Output #2

2.4Set by Communications Link

2.5Commanded Motor Speed

3.0Output impedance is less than 100 ohms.

4.0Maximum output voltage is +/- 10VDC.

5.0Maximum current is 25mADC.
