Appendix I (accessoires) : “IOBOX”
Product description
It is a I / O expansion module for the LVD drive with DIN rail mounting capability. The
number of digital inputs is 16, they are 24V pnp compatible. The digital outputs are 8, 24V
pnp able to drive up to 50 mA each, but the total current fed from the digital outputs has not to
exceed 150 mA. The link between the IOBOX and the LVD drive is made using the SBCCAN
protocol, in communication mode at 125Kbps. Every 5ms the IOBOX send the status of the
digital inputs using the broadcast command in the Pr89 and read the status of the outputs from
the drive addressed with 0 ( Pr27=0 ) in Pr91.8..Pr91.15 performing physically the output
operation. On IOBOX are present two led for a easy diagnostic, the red one is the power
supply status, the green one is the link status, if it is always on the link is OK, if it flash once
the link is in busoff, if it flash twice the link is in bus warning.
