The SMC30 Sensor Module is used for detecting the
actual motor speed.
The following encoders are supported by the SMC30
Sensor Module:
TTL encoder

HTL encoder

SSI encoder

(→ See the chapter titled "Options", section "K50, SMC30
Sensor Module for detecting the actual motor speed")
Voltage sensing module VSM10 is used to operate a
permanent-magnet synchronous machine without encoder
with the requirement for switching to a machine which is
already running (flying restart function).
To commission the function, the permanent-magnet
synchronous machine without encoder must be input and
"Flying restart" activated with p1200.
(→ See the section "Options", section "K51, VSM10
Voltage Sensing Module cabinet-mounted")
The additional SMC30 Sensor Module is used for safe
actual value sensing when using the Safety Integrated
Extended Functions.
(→ See the section "Options", section "K52, Additional
SMC30 Sensor Module")
Voltages 1 AC 230 V and 24 V DC of the auxiliary power
supply system must be supplied externally.
(→ See Chapter "Options" in the section "K70, fan power
supply")
In order to supply the auxiliary voltage supply system with
the appropriate voltages, the phase must be connected to
the corresponding transformer tap.
Make sure that the correct voltage is applied!
(→ See the chapter titled "Options", section "K76, auxiliary
voltage generating unit in the Line Connection Module")
Connect according to "Cable routing for the "Safe Torque
Off" and "Safe STOP 1" functions".
(→ See the chapter titled "Electrical installation", in the
section "Cable routing for the "Safe Torque Off" and "Safe
STOP 1" functions")
(→ See the Chapter titled "Options", in Section "K82,
terminal module for activating safety functions "Safe
Torque Off" and "Safe STOP 1"")
