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")
In order to supply the auxiliary voltage busbar system with
the appropriate voltages, the phase must be clamped 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 "Options", section "Cable routing
for the "Safe Torque Off" and "Safe STOP 1" functions")
(→ See the chapter titled "Options", section "K82, terminal
module for activating safety functions "Safe Torque Off"
and "Safe STOP 1"")
Wire up the checkback contact.
(→ See the chapter titled "Options", section "L25, circuit
breaker in withdrawable unit design")
Include the option in the EMERGENCY OFF chain.
(→ See the chapter titled "Options", section "L45,
EMERGENCY OFF pushbutton in the cabinet door")
The interlock for the upstream, plant-side main breaker
must be ensured.
(→ See the chapter titled "Options", section "L46/L47,
grounding switch upstream/downstream of circuit breaker")
The main breaker cannot be closed when the grounding
switch is closed.
(→ See the chapter titled "Options", section "L46/L47,
grounding switch upstream/downstream of circuit breaker")
