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)").
The connecting cables and ground for the braking resistor must
be connected to terminal block –X5: 1/2. The braking resistor
thermostatic switch and customer terminal block –A60 or the
Control Unit must be connected. 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 / Fur-
ther connections / Braking unit 50 kW (option L62)").
The PTC thermistor sensors (PTC resistor type A) must be con-
nected to the thermistor motor protection unit -F127 at terminals
T1 and T2 for alarms (see "Electrical installation / Other connec-
tions / Thermistor motor protection device (option L83/L84)").
The PTC thermistor sensors (PTC resistor type A) must be con-
nected to the thermistor motor protection unit -F125 at terminals
T1 and T2 for shutdown (see "Electrical installation / Other con-
nections / 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 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).
The insulation monitor can only be operated on a non-grounded
line supply (IT system). Only one insulation monitor can be de-
ployed in an electrically-connected network. For in-plant control,
the signaling relays must be connected accordingly or, with indi-
vidual drives (the cabinet unit is fed via a converter transformer
assigned to the cabinet unit), integrated in the cabinet unit alarm
chain (see "Electrical installation / Other connections / Insulation
monitoring (option L87)").
Point 9 must also be observed:
"Before the drive is operated on a non-grounded line supply (IT
system), the connecting clip to the basic interference suppression
module must be removed" (see "Electrical installation/Power
connections/Removing the connection clip to the basic interfer-
ence suppression module for operation on non-grounded line
supplies (IT systems)").
