28 Operation principle and hardware description
Cables for connecting the control unit to the drive module and
control panel
The cables connecting the drive module and control panel to the control unit are shown
below. See section Connecting the control unit to the drive module, page 79 for the actual
connections.
Circuit boards
The drive contains the following printed circuit boards as standard:
• main circuit board (JINT)
• control and I/O board (JCON) inside the JCU Control Unit
• adapter board (JRIB) connected to the JCON board
• input bridge control board (AINP)
• input bridge protection board (AIBP) which includes snubbers for the thyristors and
varistors
• power supply board (APOW)
• gate driver control board (AGDR)
• diagnostics and panel interface board (JDPI)
Type designation label
The type designation label includes an IEC and NEMA rating, CE, “C-tick”, C-UL US, and
CSA markings, a type designation and a serial number, which allow individual recognition
of each unit. The first digit of the serial number refers to the manufacturing plant. The next
four digits refer to the unit’s manufacturing year and week respectively. The remaining
digits complete the serial number so that there are no two units with the same serial
