Start–Up and Adjustment

Publication 1397-5.0 — June, 2001

The HIM displays the correct position of the jumper under the
Diagnostics menu [J18 Arm Fdbk Res] (P.183). Verify this jumper
setting before performing the self-tuning procedure.

Table 4.J lists the standard 1397 I/O input points indicating those
hardware inputs which are required for Drive operation. Some of
these signals may be generated by the terminal strip or a SCANport
device or HIM or both. These signals are identified in the table by
the column labeled “Alternate Control Source”.

NOTE: Required signals MUST be correctly wired to the terminal
strip for proper Drive operation, and cannot be masked. Signals that
are not required may be “masked off” for exclusive control by a
SCANport device or HIM. Masking parameters are described in
detail in Chapter 5: Programming Parameters.

IMPORTANT: Regulator Board terminal Strip Inputs 3, 8, 9, 12 and
13 must be closed for the Drive to be ready.
