LEESON Micro Series Compact Inverters - Manual (Page 37)

14.2 START/STOP AND SPEED CONTROL
14.2.1 REMOTE MODE SELECTION
The REMOTE mode can be selected by one of two methods:
1 . Program Parameter 30 - CONTROL to REMOTE, or:
2. Program CONTROL to BOTH, set the TB-13A or TB-13C function (see Parameter 47 or 49) to
LOCAL SELECT, and DO NOT make a contact closure between TB-13A or TB-13C and TB-2
(making the contact closure will select LOCAL mode).
If CONTROL is set to LOCAL, TB-1 is disabled and CANNOT be used as a STOP switch!
Incorrect use of TB-1 may result in damage to equipment and/or injury to personnel! See
Parameter 30 - CONTROL .
STOP (TB-1) and EXTERNAL FAULT (TB-13D) circuitry may be disabled if parameters are
reset to factory defaults! The drive must be reprogrammed after a RESET in order to insure
proper operation (see Parameter 65 - PROGRAM).
FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR INJURY
TO PERSONNEL!
14.2.2 TWO-WIRE START/STOP CONTROL
A two-wire start/stop circuit can be accomplished by one of three methods on the MICRO Series drive .
Follow the appropriate procedure listed below:
FORWARD ROTATION ONLY
1. Select REMOTE mode (see 14.2.1).
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 . Closing this contact will RUN
the drive and opening this contact will STOP the drive .
FORWARD and REVERSE ROTATION
1. Select REMOTE mode (see 14.2.1).
2 . Program Parameter 27 - ROTATION to FWD & REV to allow rotation in both directions .
3 . Program Parameter 49 - TB13C to START REVERSE . This will force TB-12A to act as START
FORWARD .
4 . Select the desired rotation by closing the appropriate terminal (TB-12A for forward, or TB-13C for
reverse) to TB-2. This can be done with a toggle switch or equivalent circuit.
5 . 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 .
