Error group 7
Overvoltage in intermediate circuit
No.

Intermediate circuit overvoltage
PSoff
Cause
Braking resistor is overloaded; too much braking energy, which
cannot be dissipated quickly enough.
–
Incorrect level of resistance?
–
Resistor not connected correctly?
–
Check design (application).
Measure
Check the design of the braking resistor; resistance value may
be too great.
Check the connection to the braking resistor (internal/ex
ternal).

Cause
Resolver signal amplitude is faulty.

Additional
informa
tion
a) If possible, test with a different (error-free) resolver (replace the
connecting cable, too). If the error still occurs, there is a fault in
the motor controller. Repair by the manufacturer required.
b) If the error occurs only with a special resolver and its connecting
cable: Check resolver signals (carrier and SIN/COS signal), see
specification. If the signals do not comply with the signal spe
cifications, replace the resolver.
c) If the error recurs sporadically, check the screen bonding or
check whether the resolver simply has an insufficient transmis
sion ratio (standard resolver: A = 0.5).
