204 Options CG Drives & Automation 01-7492-01r1
The brake chopper option is built-in by the manufacturer
and must be specified when the AC drive is ordered.
13.8 I/O Board
Each I/O option board 2.0 provides three extra relay outputs
and three extra isolated digital inputs (24V). The I/O Board
works in combination with the Pump/Fan Control, but can
also be used as a separate option. Maximum 3 I/O boards
possible. This option is described in a separate manual.
13.9 Encoder
The Encoder 2.0 option board, used for connection of
feedback signal of the actual motor speed via an incremental
encoder is described in a separate manual.
For Emotron FDU and for VFX in V/Hz mode this
function is for speed read-out only or for spin start function.
No speed control.
13.10 PTC/PT100
The PTC/PT100 2.0 option board for connecting motor
thermistors and max 3 PT100 elements to the AC drive is
described in a separate manual.

NOTE: Although the AC drive will detect a failure in
the brake electronics, the use of resistors with a
thermal overload which will cut off the power at
overload is strongly recommended.
