EMERGENCY STOP category 1 stops the drive in a controlled
manner. With this option, braking units (brake chopper and
external braking resistors) may need to be fitted due to the load
characteristic and to achieve the required shutdown times. 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.
The timer relay at -K121 must be adapted to match system
requirements (see "Electrical installation / Other connections /
EMERGENCY STOP category 1, 230 V AC (option L59)").

The timer relay at -K120 must be adapted to match system

EMERGENCY STOP category 1, 24 V AC (option L60)").
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 or the Control Unit. 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 / Other connections / Braking unit 25 kW /
125 kW (option L61); braking unit 50 kW / 250 kW (option L62)").
The PTC thermistor sensors (PTC resistor type A) must be
connected to the thermistor motor protection unit -F127 at
terminals T1 and T2 for alarms (see "Electrical installation / Other
connections / Thermistor motor protection device (option
L83/L84)").
The PTC thermistor sensors (PTC resistor type A) must be
connected to the thermistor motor protection unit -F125 at
terminals T1 and T2 for shutdown (see "Electrical installation /
Other connections / Thermistor motor protection device (option
L83/L84)").
The resistor thermometers must be connected to evaluation units
-B140, -B141 for the PT100 evaluation. A two-wire or three-wire
system can be used here to connect the PT100 sensors. The
sensors are divided into two groups (see "Electrical installation /
Other connections / PT100 evaluation unit (option L86)"). This
must be taken into account for the evaluation (factory setting).
