Refer to Figure 3.1 on page 77 when wiring terminals on the bypass and drive control circuits.
u Control Circuit Terminal Block Functions
WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a bypass 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
Z1-01 may change the I/O terminal function automatically from the default setting. Refer to Application Selection on page 123 . Failure
to comply may result in death or serious injury.
The functions of the control circuit terminals are shown in Table 3.7 .
The control circuit terminals on Terminal Board A2 are arranged as shown in Figure 3.18 .
