3.2
Motor encoder
The motors are equipped with various encoder systems to sense the rotor posi-
tion and speed.
Reference:
refer to Appendix B in the relevant Configuration Manual
of the motors
The assignment of the SIMODRIVE units to the servo/main spindle motor types
and encoder systems is shown in the Table 3-5.
Depending on the requirements, various types of encoder are used and pro-
cessed in the appropriate modules:
sin/cos 1 Vpp or EnDat encoder
SSI encoder (only SIMODRIVE 611 High Performance, High Standard, HLA/
ANA)
Resolver (only SIMODRIVE 611 universal)
TTL encoder (only SIMODRIVE 611 universal with induction motors)
Induction motors can also be operated without encoders.
The modules provide high encoder resolutions with internal pulse multiplication.
The following encoder signals are recommended for fault–free operation:
