Programmable Outputs

The BLU-Si drives feature seven digital outputs:
Brake/Y1

Brake/Y1

Brake/Y1: controls an electric brake relay, automatically releasing and engaging as the drive
requires
Alarm/Y2

Alarm/Y2

Alarm/Y2: closes when a drive fault or alarm condition occurs. The red and green LEDs will flash
an error code.
In Position/Y3

In Position/Y3

In Position/Y3: indicates that the drive has achieved a desired goal, such as a target position.

Y1, Y2 and Y3 can be configured as dedicated, automatic Brake, Fault and In Position outputs or

Wiring a Limit Sensor

Some systems use active limit sensors that produce a voltage output rather than a switch or relay
closure. These devices must be wired differently than switches.

If your sensor has an open collector output or a sinking output, wire it like this:

CW LIMIT-

If the sensor output goes low at the limit, select the option “closed” (in the software). If the output
is open, or high voltage, choose “open”.

Other sensors have sourcing outputs. That means that current can flow out of the sensor output,
but not into it. In that case, wire the sensor this way:

If the sensor output goes high at the limit, choose the program option “closed”. If the output is low
at the limit, select “open”.
