The SMC30 Sensor Module is used for detecting the actu-
al motor speed.
The following encoders are supported by the SMC30 Sen-
sor Module:
TTL encoder
•
HTL encoder
•
SSI encoder
•
(→ See Chapter "Options", Section "K50, SMC30 Sensor
Module for detecting the actual motor speed")
The VSM10 Voltage Sensing Module is used to sense the
voltage characteristic on the motor side, so that the follow-
ing functions can be implemented:
Operation of a permanent-magnet synchronous motor
•
without encoder with the requirement to be able to
connect to a motor that is already running (flying restart
function).
Fast flying restart of large induction motors: The time
•
for the demagnetization of the motor is eliminated as a
result of the voltage sensing.
When operating a permanent-magnet synchronous motor
without encoder, the "Flying restart" function must be acti-
vated with p1200.
(→ See Chapter "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 Chapter "Options", Section "K52, Additional
SMC30 Sensor Module")
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 Chapter "Options", Section "K76, auxiliary voltage
generating unit in the Line Connection Module")
Establish the connection according to "Cable routing for
the functions TM54F".
(→ See Chapter "Electrical installation", Section "Cable
routing for the Terminal Module TM54F")
(→ See Chapter "Options", Section "K87, Terminal Module
TM54F")
To control the brake, a connection must be established
between -X14 on the Safe Brake Adapter and the holding
brake.
(→ See Chapter "Options", Section "K88, Safe Brake
Adapter SBA 230 VAC")
