SINAMICS6SL3210-1KE21-7AP1
Example: Single-encoder system
In a single-encoder system, the motor encoder is used exclusively for safe actual value sensing.
Dual-encoder system
Example: Dual-encoder system
In the case of the 2-encoder system, the safe actual values for a drive are provided by two separate encoders. The actual values are transferred to the Control Unit over DRIVE-CLiQ. When motors without a DRIVE-CLiQ connection are used, a Sensor Module must be provided.
HTL/TTL incremental encoders can be used as an alternative with a dual-encoder system. Either two HTL/TTL encoders, one dual-HTL/TTL encoder or one HTL/TTL encoder and one sin/cos encoder can be used.
The safety functions are listed below with criteria for actual value sensing

Diagnostic function for safe testing of the required holding torque of a brake |
1) The use of this safety function without encoder is permitted for induction motors or synchronous motors of the SIEMOSYN series.
2) Only for the transmission of relative b values. An encoder is required to transmit absolute b values.
