3.7 Control Circuit Wiring

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 analog inputs (A1 to A3), and multi-function analog monitor output (FM, AM). The default setting
is listed next to each terminal in Figure 3.1 on page 81.
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 134. Failure
to comply may result in death or serious injury.

Safe Disable
Inputs
H1 Safe Disable input 1 • 24 Vdc, 8 mA
•
One or both open: Output disabled
• Both closed: Normal operation
• Internal impedance: 3.3 kΩ
• Off time of at least 1 ms
• Disconnect the wire jumpers shorting terminals H1, H2, and HC
