FREQUENCY INPUTS AND

OUTPUTS

There is one frequency input and there are two frequency outputs available.

INPUT

#1 REFERENCE FREQUENCY INPUT

TB2:A Terminals 11 (+) and 12 (-).

•This is a line receiver type input which must be driven by a differential line driver output.

•This frequency input requires a frequency 16 times the feedback from the motor.

•The feedback from the motor is normally 120 PPR for 4 pole motors and 240 PPR for 8 pole motors.

•Normal input is 56 Kilohertz for 0 to full speed for a 1750 RPM motor with a 120ppr encoder.

•Terminal 13 is for the shield. Do not ground terminal 13 directly. It is internally terminated.

OUTPUTS

#1 REFERENCE FREQUENCY OUTPUT

TB2:B Terminals 10 (+) and 11 (-),

•This is a differential line driver output which must be used with a differential line driver input.

•This frequency output is 16 times the reference frequency to the motor.

•This output may drive up to 32 receivers.

•Connect the shield to terminal 12. This will ground the shield internally.

#2 MOTOR SPEED FREQUENCY OUTPUT TB2:B Terminals 13 (+) and 14 (common),

•This output is a +24VDC peak square wave at the motor feedback pulse rate, which is 2 times RPM for 4 pole motors and 4 times RPM for 8 pole motors.

The reference frequency input and output are capable of receiving and sending at up to 1 Mega- hertz.

Motor Speed output emits frequencies up to 100 Kilohertz.

DIGITAL INPUTS

The eight digital inputs of the DFS-1 are optically coupled requiring +24VDC (+/-6VDC) at about 5mA each. These inputs are isolated from the common of the board.

All inputs are programmable as to function, EXCEPT the EMERGENCY STOP input. Inputs #1 through #7 may be assigned as general purpose inputs.

The defaults are as follows:

 

TB2:A terminal 3(+)

Emergency Stop

 

(Cannot be reassigned)

 

DI 1.

TB2:A4(+)

Run

DI 2.

TB2:A5(+)

Preset Speed

DI 3.

TB2:A6(+)

Up (Increase)

DI 4.

TB2:A7(+)

Down (Decrease)

DI 5.

TB2:A8(+)

Reverse

DI 6.

TB2:A9(+)

Frequency Mode

DI 7.

TB2:A10(+)

Local/Remote

Inputs #1 through #7 may also be programmed for inverted input, i.e., active when input is low.

DIGITAL OUTPUTS

There are four dry contact outputs from the DFS-1. All of these outputs are on TB2:B. All outputs are programmable as to function, and all outputs may be set up as either normally open or normally closed.

Each relay output has a single, isolated, contact output which may be programmed as normally open or normally closed, with the contact rated at 1 Amp, 125VAC resistive.

The default assignments are as follows:

DO 1.

TB2:B terminals 2 and 3

Run relay contact

 

Closed while running

 

DO 2.

TB2:B terminals 4 and 5

No fault relay

 

Closed while no faults

 

DO 3.

TB2:B terminals 6 and 7

At Speed relay

 

Closed when at speed

 

DO 4.

TB2:B terminals 8 and 9

Remote Mode

 

Closed when in Remote
