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 .
