4.2.10 Feedback systems
Different feedback systems can be connected to the controller:
• Resolver feedback (factory setting)
• Encoder feedback
– Incremental encoder TTL
– Sin-cos encoder
– Sin/cos encoder with serial communication (single turn)
– Sin/cos encoder with serial communication (multi turn)
Resolver signal or encoder signal can be output for slaves at the digital frequency output X10.
• Connection as shown in the figures:
– Use twisted pair cables and screened pair cables.
– Connect the screen at both ends.
– Use the indicated cable cross-sections.
• The feedback system is activated under C0025.
Resolver connection (X7)
• A resolver can be used as feedback system at this input. An adjustment is not necessary.
Tip!
Use the prefabricated Lenze system cable for the resolver connection.
Features:
• 2-pole resolver (V = 10 V, f = 4 kHz)
• Resolver and resolver cable are monitored for open circuit
