Item  Activity  Fulfilled/Complete 
17  Option K48 
SMC20 Sensor 
Module 
The SMC20 Sensor Module is used for determining the actual motor 
speed and the path length. 
The following encoders are supported by the SMC20 Sensor Module: 
•  Incremental encoder sin/cos 1Vpp 
•  Absolute encoder EnDat 
(See "Electrical installation / SMC20 Sensor Module for detecting the 
actual motor speed and the path length (option K48)".) 
 
18  Option K50 
SMC30 Sensor 
Module 
The SMC30 Sensor Module is used for determining the actual motor 
speed. 
The following encoders are supported by the SMC30 Sensor Module: 
•  TTL encoder 
•  HTL encoder 
•  SSI encoder 
(See "Electrical installation / SMC30 Sensor Module for detecting the 
actual motor speed (option K50)".) 
 
Connecting protection and monitoring devices 
19  Option L45 
EMERGENCY 
STOP 
pushbutton 
The contacts for the EMERGENCY STOP pushbutton are connected 
to terminal -X120 and can be picked off so that they can be integrated 
in a higher-level line-side protection concept ("Electrical installation / 
EMERGENCY STOP pushbutton (option L45)"). 
 
20  Option L57 
EMERGENCY 
STOP category 
0  
(230 V AC /  
24 V DC) 
EMERGENCY STOP 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, however, 
the contact must be looped in via terminal block -X120 ("Electrical 
installation / EMERGENCY STOP category 0; 230 V AC / 24 V DC 
(option L57)"). 
 
21  Option L59 
EMERGENCY 
STOP category 
1  
(230 V AC) 
EMERGENCY STOP category 1 stops the drive in a controlled 
manner. No additional wiring is necessary when implemented in 
conjunction with option L45. If the cabinet unit is integrated in an 
external safety circuit, however, the contact must be looped in via 
terminal block –X120 (see "Electrical installation / EMERGENCY 
STOP category 1; 230 V AC (option L59)"). 
 
22  Option L60 
EMERGENCY 
STOP category 
1  
(24 V DC) 
EMERGENCY STOP category 1 stops the drive in a controlled 
manner. No additional wiring is necessary when implemented in 
conjunction with option L45. If the cabinet unit is integrated in an 
external safety circuit, however, the contact must be looped in via 
terminal block –X120 (see "Electrical installation / EMERGENCY 
STOP category 1; 24 V DC (option L60)"). 
 
23  Option 
L61/L62/L64/L6
5 
25/50 kW 
braking unit 
The connecting cables and ground for the braking resistor must be 
connected to terminal block –X5: 1/2. A connection must be 
established between the braking resistor thermostatic switch and 
customer terminal block –A60. When commissioning via AOP30, the 
settings for evaluating "external fault 3" must be made. The settings 
for evaluating the thermostatic switch as "external fault 2" must be 
made (see "Electrical installation / 25 kW Braking unit (option 
L61/L64); 50 kW Braking unit (option L62/L65)").
