 Control Circuit Connection Diagram
Refer to Standard Connection Diagram on page 60
 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
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! 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.

Function (Signal Level) Default Setting
Photocoupler
24 Vdc, 8 mA
Set the wire jumper between SC and SN or SC and SP for selection of sinking/
sourcing mode and power supply. Refer to
Inputs on page 88.
Multi-function input common
24 Vdc power supply for digital inputs, 150 mA max (if no digital input option
DI-A3 is used only)
Never short terminals SP and SN as doing so will damage the drive.
24 Vdc, 8 mA
One or both open: Output disabled
Both closed: Normal operation
Internal impedance: 3.3 k
Off time of at least 1 ms
Disconnect the wire jumpers shorting terminals H1, H2, and HC to use the Safe
Disable inputs. Set the S3 jumper to select between sinking, sourcing mode, and the
power supply as explained in Sinking/Sourcing Mode Selection for Safe Disable
Inputs on page 88.
Safe disable function common
Input frequency range: 0 to 32 kHz
Signal Duty Cycle: 30 to 70%
High level: 3.5 to 13.2 Vdc, low level: 0.0 to 0.8 Vdc
Input impedance: 3 k
10.5 Vdc (max allowable current 20 mA)
-10.5 Vdc (max allowable current 20 mA)
-10 to 10 Vdc, 0 to 10 Vdc (input impedance: 20 k)
-10 to 10 Vdc, 0 to 10 Vdc (input impedance: 20 k)
4 to 20 mA, 0 to 20 mA (input impedance: 250 )
Voltage or current input must be selected by DIP switch S1 and H3-09
-10 to 10 Vdc, 0 to 10 Vdc (input impedance: 20 k)
Use DIP switch S4 on the terminal board to selection between analog or PTC input.
