Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S8), multi-function digital
outputs (M1 to M6), multi-function photocoupler outputs (P1, P2), multi-function analog inputs (A1 to A3), and
multi-function analog monitor outputs (FM, AM). The default setting is listed next to each terminal in
Figure 3.34 and
Figure 3.35 .
WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive
with untested control circuits could result in death or serious injury.
WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before starting test run. Setting
parameter A1-06 may change the I/O terminal function automatically from the factory setting. Refer to Application Selection on
page 148 . Failure to comply may result in death or serious injury.

Input Terminals
Table 3.10 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
input.
Table 3.10 Control Circuit Input Terminals
Type
<1> Terminal SP and SN are available in CIMR-UB  only.
<2> Setting jumper S3 for an external power supply makes the wire link between terminals H1, H2, and H2 ineffective. Remove the wire link and
connect an external power supply that can supply terminals H1, H2, and HC continuously.
