A controller compares the encoder system supply voltage - sensed via the Remote Sense cables - with the reference supply
1)
voltage of the encoder system, and adjusts the supply voltage for the encoder system at the output of the sensor module until
the required supply voltage is obtained directly at the encoder system (only for 5 V encoder system power supply).
Only possible for SSI encoders with 5 V supply.

Current controller clock cycle
For a current controller cycle clock of 31.25 µs, use an SMC20 with Article No.

Description

The Sensor Module Cabinet-Mounted SMC30 is an expansion module for snapping on to a
standard mounting rail acc. to EN 60715. It evaluates encoder signals and transmits the speed,
actual position, and, if applicable, the motor temperature and reference point via DRIVE-CLiQ to
the Control Unit.
The SMC30 is used to evaluate encoder signals from encoders with TTL, HTL, or SSI interfaces.
A combination of TTL/HTL signal and SSI absolute signal is possible at terminals X521/X531, if
both signals are derived from the same measured variable.
