T1, T2, T3

Motor output terminals. Connect these terminals to a 3-phase

 

(U, V, W)

induction motor of the proper voltage, current, and horsepower.

 

PA, PB

Braking resistor output terminals. Connect to an external dynamic

 

 

braking resistor (available only on 30 HP and smaller drives).

 

FLA, FLB, FLC

Programmable relay contact output. The contact rating is

 

 

250VAC - 2A. Default setting closes FLA-FLC and opens FLB-FLC

 

 

when protective function has been activated.

 

P24

Unregulated 24Vdc power supply (24Vdc, 50mA maximum). P24 is

 

 

protected by fused resistor found on the terminal board (see p. 5-1).

 

RCH(A & C)

Programmable relay contact output. Standard setting closes

 

 

contact when an acc/dec is complete, or when the output

 

 

frequency is within a specified range. Contact rating is 250Vac - 2A.

 

LOW(A & C)

Programmable relay contact output. Standard setting closes

 

 

contact when a preset low speed or a preset lower limit is

FM*

Programmable analog output. Outputs 0 - 1mA or 4 - 20mA (set by

 

 

JP4 on terminal board (see section 5.1)). This terminal can

 

 

be connected to an external analog meter. Use either an ammeter

 

 

rated 1mA DC/20 mA DC at full scale or a voltmeter rated 7.5Vdc at

 

 

full scale (true analog output). See page 9-23 for programming.

 

AM*

Programmable analog output. Outputs 0 - 1mA or 4 - 20mA (set by

 

 

JP3 on terminal board (see section 5.1)). This terminal can

 

 

be connected to an external analog meter. Use either an ammeter

 

 

rated 1mA DC/20 mA DC at full scale or a voltmeter rated 7.5Vdc at

 

 

full scale (true analog output). See page 9-23 for programming.

 

FP

Dedicated open-collector output. Pulses that are 48, 96, or

 

 

360-times the output frequency are available according to the

 

 

parameter settings (must connect external supply through pull-up

 

 

resistor to measure output).

 

* Do not make/break connections to these terminals with the drive powered.
