Operating Instructions, 07/2016, A5E03347396A
The SMC30 Sensor Module determines the actual motor speed.
In conjunction with SINAMICS G150, the following encoders are
supported by the SMC30 Sensor Module:
TTL encoder
•
HTL encoder
•
The motor temperature can also be detected using KTY84-130 or
PTC thermistors.
In the factory setting, an HTL encoder is bipolar with 1024 pulses
per revolution (see "Electrical installation / Other connections /
SMC30 Sensor Module Cabinet-Mounted (option K50)").
For reliable actual value acquisition when using the Safety Inte-
grated Extended Functions, the additional SMC30 Sensor Module
is used (see "Electrical installation/Other connections/Additional
SMC30 Sensor Module (option K52)").
The TM150 Terminal Module can be connected to a maximum of
12 temperature sensors (PT100, PT1000, KTY84, PTC, bimetallic
NC contact) (see "Electrical installation/Other connections/TM150
Temperature Module (option G51)").
The contacts for the EMERGENCY OFF pushbutton are available
at terminal -X120 and can be picked off so that they can be inte-
grated in an on-site higher-level protection concept (see "Electri-
cal installation / Other connections / EMERGENCY OFF
pushbutton, integrated in the door of the cabinet unit (option
L45)").
EMERGENCY OFF category 0 stops the drive in an uncontrolled
manner. No additional wiring is necessary when implemented in
conjunction with option L45.
If the cabinet unit is integrated in an external safety circuit, how-
ever, the contact must be looped in via terminal block -X120 (see
"Electrical installation/Other connections/EMERGENCY OFF
category 0, 230 VAC / 24 VDC (option L57)").
EMERGENCY STOP category 1 stops the drive in a controlled
manner. It may be necessary to use braking units because of the
load characteristic and the required shutdown times. No addition-
al wiring is necessary when implemented in conjunction with
option L45.
If the cabinet unit is integrated in an external safety circuit, how-
ever, the contact must be looped in via terminal block –X120. The
timer relay at -K121 must be adapted to match system require-
ments (see "Electrical installation / Other connections /
EMERGENCY STOP category 1, 230 VAC (option L59)").
