4.4.4. Encoder 2 Connector (J4)
The Encoder 2 connector is D-type, 9-pin, female.
Warning
Facilities for overspeed protection are not provided in the control unit.
Therefore, when facilities for overspeed protection are required for the end-
product, they will have to be provided separately by the end-user.
The interface of the Encoder 2 connector is identical to the interface of Encoder 1 connector.
Common uses for the Encoder 2 connection are master/slave and dual-loop control.
The Encoder 2 can be powered by the on-board +5L (5V). The total current consumption must not
exceed 0.5A. If the +5L current consumption exceeds 0.5A, an external supply must be used. In
such a case, the return of the supply must be connected to GND pin.

4.4.5. I/O + Safety Connector (J3)
The I/O + Safety connector is D-type, 25 pin, male.
There are 8 digital inputs, 8 digital outputs, two limit inputs, one E_STOP input, one analog input,
and one analog output.
All the digital I/O are isolated.
Warning
The Emergency Stop and Safety Interlock means provided with the controller are
software-based only. Therefore, if the end product requires facilities for hardware-based
Emergency Stop and/or Safety Interlock, these must be provided separately by the end
user.
