Jetter AG 103
14.3 Synchronous Serial Interface (SSI)
14.3.1 Technical Data
14.3.2 Description of Connections
Specification of Mating Connector for X72
• 9-pin male SUB-D connector
• Metallized enclosure
Specification of SSI Cable
• Cable size: 2 * 2 * 0.14 mm² + 2 * 0.25 mm² (AWG 26(4) + AWG 23(2))
2 * 0.25 mm² has to be used for power supply and GND.
• The cables have to be twisted in pairs and included in an overall shielding.
• The following signal lines have to be twisted in pairs:
Clock - and Clock +
DATA - and DATA +
0 V and voltage supply
• The shield has to be connected to the connector housings on both ends of the
cable with the greatest possible surface area.
• Material: Copper
• Temperature class: 60 °C
• Maximum cable length: 100 m
Dependent on the encoder type, the transmission frequency has to be reduced
due to the signal runtimes in long cables.
