YASKAWA Europe TOEP C710616 88A - AC Drive A1000 IP23/54 Floor Standing - Quick Start Guide
Function (Signal Level) Default Setting
Photocoupler
24 Vdc, 8 mA
Use the wire link between terminals SC and SN or SC and SP
to select between sinking, sourcing mode, and the power
supply.
–
24 V DC power supply for digital inputs, 150 mA max (if no
digital input option DI-A3 is used)
Never short terminals SP and SN as doing so will damage the
drive.
24 V DC, 8 mA
One or both open: Drive 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.
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 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 switch S4 on the control terminal board to select between
analog input or PTC input. If PTC is selected, set H3-06 = E.
