3.5.3.1. J3 General I/O Port
Port J3 has a 9‐pin D‐Sub female connector. When assembling this I/O cable, follow the
instructions in Section 3.5.2 Control, I/Os and Halls Cable Assemblies using a 9‐pin a metal case
D‐Sub male connector (plug).
Pin Signal Function Description Pin Position
1 AOK Amplifier
OK
When the amplifier under normal
operating conditions, this output is in
the “active low“ state. When a failure
occurs, this output is changed to the
“open” state.
The optocoupler is an isolated, open
collector NPN type.
Maximum voltage = 30 V
Maximum current = 8 mA
“On” voltage: V
OUT(On)
< 0.8 V
9‐Pin Female
2 SO1 Status
output 1 Status indication output 1. Specification
same as in pin J3/1.
3 SO2 Status
output 2 Status indication output 2. Specification
same as in pin J3/1.
4 SO3 Status
output 3 Status indication output 3. Specification
same as in pin J3/1.
5 EN+ Enable +
“Amplifier Enable” function. To enable
operation of the amplifier, the
optocoupler must be energized by
applying voltage between this pin (+) and
pin J3/6 (‐).
The optocoupler is isolated from the
amplifier.
“OFF” voltage: 0 V < Vin < 1 V.
“ON” voltage: 2.5 V < Vin < 10 V, 5 V
typically with current consumption
2.5 mA.
6 EN‐ Enable ‐
Negative voltage input of “Amplifier
Enable” function.
Optocoupler is isolated from the
amplifier. For details, see pin J3/5.
7 SORET Status
output
return Status output common AOK, SO1, SO2,
SO3.
Isolated from circuit common.
8 SORET Status
output
return Status output common AOK, SO1, SO2,
SO3.
Isolated from circuit common.
9 SORET Status
output
return Status output common AOK, SO1, SO2,
SO3.
Isolated from circuit common.
