Electrical installation
Measuring the insulation
See the electrical installation instructions of the drive.
Connecting power cables
See the electrical installation instructions of the drive.
Connection the control cables
Connect the thermal switch of the brake resistor as described in Protecting the
system against thermal overload (page 139).
Start-up
Set the following parameters:
1. Disable the overvoltage control of the drive with parameter
30.30 Overvoltage
control
.
2. Set the source of parameter
31.01 External event 1 source
to point to the digital
input where the thermal switch of the brake resistor is wired.
3. Set parameter
31.02 External event 1 type
to
Fault
.
4. Enable the brake chopper by parameter
43.06 Brake chopper enable
. If
Enabled
with thermal model
is selected, set also the brake resistor overload protection
parameters
43.08
and
43.09
according to the application.
5. Check the resistance value of parameter
43.10 Brake resistance
.
With these parameter settings, the drive generates a fault and coasts to a stop
on brake resistor overtemperature.
