18 Option L60
EMERGENCY
STOP category
1, 24 VDC
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 -K120 must be adapted to match system require-
ments (see "Electrical installation / other connections /
EMERGENCY STOP category 1, 24 VDC (option L60)").
19 Option L62
Braking unit
50 kW / 200 kW
The connection cables and the grounding for the braking resistor
must be connected to terminals G and H on the Braking Module.
The thermoswitch on the braking resistor and the terminal
-X30:10/11 unit must be connected (see "Electrical installation /
additional connections / braking unit 50 kW (option L62)").
20 Option L83
Thermistor mo-
tor protection
device (alarm)
The PTC thermistor sensors (PTC resistor type A) must be con-
nected to the thermistor motor protection device -F127 at termi-
nals T1 and T2 for alarm (see "Electrical installation / Other
connections / Thermistor motor protection device (option
L83/L84)").
21 Option L84
Thermistor mo-
tor protection
device (shut-
down)
The PTC thermistor sensors (PTC resistor type A) must be con-
nected to the thermistor motor protection device -F125 at termi-
nals T1 and T2 for shutdown (see "Electrical installation / Other
connections / Thermistor motor protection device (option
L83/L84)").
22 Option L86
PT100 tripping
unit
The resistor thermometers must be connected to evaluation units
-B140, -B141 for the PT100 evaluation. A two-wire or three-wire
system can be implemented here to connect the PT100 sensors.
The sensors are divided into two groups (see "Electrical installa-
tion / Other connections / PT100 evaluation unit (option L86)").
This must be taken into account for the evaluation (factory set-
ting).
