instructions, injury or death can occur.
Hardware description
Product overview
The CMOD-01 multifunction extension module (external 24 V AC/DC and digital I/O)
expands the outputs of the drive control unit. It has two relay outputs and one transistor
output, which can function as a digital or frequency output.
In addition, the extension module has an external power supply interface, which can be
used to power up the drive control unit in case the drive power supply fails. If you do not
need the back-up power supply, you do not have to connect it because the module is
powered from the drive control unit by default.
WARNING! Do not connect the +24 V AC cable to the control unit ground when
the control unit is powered using an external 24 V AC supply.
