Logic Interface Options
Appendix A
A-10
1336ĆMODĆL2 +24V DC Terminal 20 and Interface Common
Logic Interface Board (cont.) (This signal must be maintained as True to permit the drive to operate from any
control source.)
Stop
Maintained True = Not stop
Momentary False = Stop
Stop must be a maintained True input to permit the drive to start and run. A
momentary False input of 20mS or more or any other drive stop command
will initiate a drive stop sequence as programmed by Parameter 10, Stop
Select.
Terminals 21, 25, 29
Interface Common
Terminals 21, 25 and 29 are specifically used to terminate both minus or
interface common signals to TB3. For the 1336-MOD-L2 +24V DC Logic
Interface Board, Terminals 21, 25 and 29 are isolated from drive signal
common, chassis ground, and earth ground.
Terminal 22 and Interface Common
Jog
True = Jog
False = Interrupt Jog and Allow Other Functions
This input will jog the drive if it is not running and interlocks permit. As
long as interlocks permit and the jog command remains True, the drive will
continue to run at the programmed jog frequency.
Terminal 23 and Interface Common
Reverse
Maintained True = Reverse
Maintained False = Forward
Parameter 22 enables the direction of drive rotation to be controlled by an
input at Terminal 23. A maintained False will select the forward direction,
a maintained True the reverse direction.
