This chapter gives a short description of the module.
Product overview
The FSE-31 safety pulse encoder interface module delivers speed,
direction and position data from the safety encoder to:
•
the functional safety system via the FSO-21 safety functions
module, and
•
to the ACS880 drive for motor control.
The FSE-31 module also monitors the operation of the encoder
and indicates faults to the FSO-21 module.
The FSE-31 module supports one HTL safety encoder. The
module has two built-in encoder interface connectors, X31 and
X32. Only X31 can be used. Interface X32 is reserved for future
use and must be left unconnected.
The FSE-31 module needs an external 24 V DC power supply
which must be connected to connector X81. For the safety
encoder, the module provides a 15 V DC power supply through
connector X31. The safety encoder must be powered from this
interface only.
Only one FSE-31 module can be installed to a drive.
