F2825 Switch-on threshold braking resistor too low
Cause
This error message is generated for devices of type
HCS when the value of the braking resistor reference
switch-on voltage (list element 4 of P-0-0858, Data
of external braking resistor) activated via
P-0-0860, Control word of power section is too
low
F2833 Ground fault in motor line
Cause
Ground fault in a motor line within drive system
- or –
Ground fault in a controller of drive system
DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com [email protected] (+34) 960 62 43 01
Supported by Firmware Variant:
For devices of the HCS type this error message is generated when the
parameterized braking resistor reference switch-on voltage is too low. The
braking resistor would already be active with correct DC bus voltage.
Remedy
Increase value of 4
external braking resistor
- or -
Select different reference value for ON-OFF switching
voltage of braking resistor in P-0-0860, Control word of
power section
F2825 - Attributes
Display:
F2825
Mess. no.:
F2825 (hex)
Supported by Supply Unit:
During the loading process of the DC bus a ground fault was detected in
the motor line of one of the connected converters/inverters.
Remedy
Take controllers of drive system successively out of
device group on control voltage and power voltage side,
until error no longer occurs. By doing this identify faulty
drive.
Check insulation of motor cable with measuring device.
If motor cable is not defective, there is a device or
connection error
F2833 - Attributes
Display:
F2833
