3. Verify that the encoder voltage selection is correct. If an encoder is

used, the drive can provide +12VDC (500 mA) to power the encoder.
Check the encoder documentation to determine which voltage is to be
used, then verify that jumpers J8 through J10 on the Main Control
Board are in the proper position. See Table 4.H for jumper settings.

NOTE: The encoder jumpers J8 – J10 are set for the voltage output of the encoder.

ATTENTION: Jumpers J8 through J10 must all be in the same
position. To guard against possible damage to the Main Control
Board, ensure that jumpers are positioned correctly for your
application.

ATTENTION: No connections should be attempted on
jumpers J12, J13, and J15. Making connection at these jumpers
could cause damage to the Main Control Board.

Control Connections

All control wiring to external devices except for contactor control is
terminated in the drive at terminal block TB3. Signal definitions for
terminals 1-20 have been predetermined and are independent of drive
application. Figure 4.5 illustrates these terminals with their signal
definitions.

TB3 is attached to a mounting rail at the bottom of the drive chassis. It
provides a wiring connection for customer supplied control and signal
devices, along with

encoder interface and auxiliary peripheral devices.

Additional individual terminal blocks can be attached to the mounting rail
to meet application requirements. These additional terminal blocks are
supplied when using an adapter board, to allow for I/O to and from the
drive.
