13.2.8. External 24V power supply
An external 24V power supply can be applied to +/- 24V terminals on ADrive. In this way even in
case of mains failure the processor unit of ADrive and ENCABIT-Plus module remain active.
In synchronous applications external 24V power supply is required!
External 24V supply must not be interrupted even in case of mains failure, in order to read
the absolute encoder data and to enable the evacuation screen in manual or automatic
evacuation mode.
The following functions remain active with external power supply even when mains power is off:
On ADrive inverter:
o Drive command inputs and relay outputs
o Incremental encoder inputs and simulation outputs
o RS-485 serial communication protocol (communication with ADrive Remote Keypad or
ARL-500 lift controller)
o CANbus connection with ENCABIT-Plus module
On ENCABIT-Plus module:
o Digital inputs and transistor outputs
o Absolute encoder inputs and simulation outputs
13.2.9. The connection between ENCABIT-Plus module and ADrive
The connection between ADrive and ENCABIT-Plus module is done with a cable with sockets at
both ends. The communication is provided through CANbus serial communication protocol.
X-ENC connector pin assignments:
24V power supply terminals (+24V: red, 0V: black)
CANbus communication terminals (CANL: green, CANH: yellow)
22-26V, min. 600mA external power supply
4-wire cable with sockets at both ends
