14.2 START/STOP AND SPEED CONTROL

14.2.1 REMOTE MODE SELECTION

In order to respond to external START/STOP commands, the drive must be in the

REMOTE mode. The REMOTE mode can be selected by one of three methods on the

MC3000 drive:

1. Program Parameter 30 - CONTROL to REMOTE.

2. Program Parameter 30 - CONTROL to KEYPAD or KEYPAD 2, which activates

the LOCAL/REMOTE key on the keypad. Press the LOCAL/REMOTE key to

select REMOTE mode, and then press the ENTER key within three seconds.

3. Program Parameter 30 - CONTROL to TB STRIP, and program the function of

terminal TB-13A or TB-13C (Parameter 47 or 49) to LOCAL SELECT. DO NOT

make a contact closure between TB-13A or TB-13C and TB-2 (making the contact

closure will select LOCAL mode).

14.2.2 TWOWIRE START/STOP CONTROL

A two-wire start/stop circuit can be accomplished as follows:

1. Select REMOTE mode (see above).

2. Connect a jumper between TB-12A and TB-2 to provide a permanent START

command to the drive.

3. Wire a normally open maintained contact between TB-1 and TB-2. Close this

contact to RUN the drive and open this contact to STOP the drive.

Refer to the wiring diagram in Section 15.2.

14.2.3 THREEWIRE START/STOP CONTROL

A three-wire start/stop circuit can be accomplished as follows:

1. Select REMOTE mode (see above).

2. Wire a normally closed momentary STOP contact between TB-1 and TB-2.

Momentarily open this contact to STOP the drive.

3. Wire a normally open momentary START contact between TB-12A and TB-2.

Momentarily close this contact to START the drive.

Refer to the wiring diagram in Section 15.3.

14.2.4 SPEED REFERENCE SIGNALS

The drive allows for three analog speed reference inputs: a speed potentiometer (10,000

Ohm), 0-10 VDC, or 4-20 mA.

SPEED POT Connect the wiper to terminal TB-5A, and connect the high and

low end leads to terminals TB-6 and TB-2, respectively.

0-10 VDC Wire the positive to terminal TB-5A and the negative to terminal

TB-2. TB-5A input impedance is 200 kilohms.

4-20 mA Wire the positive to terminal TB-5B and the negative to terminal

TB-2. TB-5B input impedance is 100 ohms.
