Rockwell Automation 1336R REGEN LINE REG - Manual (Page 77)

Regenerative Brake Operation 3–25
Control and Signal Wiring Important: Fuse R47 is self-resetting and will open should a low
impedance or short circuit occur at J15 during 24VDC
operation. Should a fault occur, allow (1) minute after
removal of power from the Converter Control Board for
R47 to cool before reapplying power.
Important: For Regenerative Brake applications, the 1336 REGEN
Package will always be used with a single 1336 AC drive.
It is recommend that the fault relay on the 1336 REGEN
Converter Control board be interconnect into the 1336 AC
drive control logic. This will allow coordination the
Regenerative Brake faults with the 1336 AC drive.
External Fault
Allows a customer supplied external signal to be wired into the 1336
REGEN Converter. Opening this contact issues an external fault
command, disabling the converter.
External Reset
Resets the 1336 REGEN Converter when closed. If the converter has
faulted, closing this contact clears the fault and resets the converter.
Enable
For the 1336 REGEN Converter to modulate, an enable signal must be
present at J15 on the 1336 REGEN Converter Control Board. Opening
this contact disables the converter. When this contact is closed, the
Enable LED on the Control Board will be lit.
Digital Output Signals
(2) form C, N.O./N.C. output relays are available at J16 on the 1336
REGEN Control Board to provide external warning or fault change-of-
state signals.
Resistive Rating = 120VAC/30VDC, 5.0A

FAULT RELAY
Fault Output - The fault output is used to indicate that
the 1336 REGEN Converter is faulted with either an
internal or external fault.
Note: The unpowered state of the fault relay is the
opposite of the faulted state—or the unpowered state
of the fault relay indicates an unfaulted condition.
Enable Output - The enable output indicates that the
1336 REGEN Converter is modulating. An enable
signal must be present on J15 and the 1336 REGEN
Converter must not be faulted for the enable output to
be active.
