Cause
•
Error in temperature measurement
when temperature sensor (KTY or
PTC) connected to encoder
interface FEN-xx is used.
•
Error in temperature measurement
when KTY sensor connected to
encoder interface FEN-01 is used.
Motor current is too high.
Brake resistor broken or not connected.
Brake resistor temperature has exceeded
warning limit defined by parameter
Brake resistor warning
limit.
Brake resistor data has not been given.
Resistance value too low.
Thermal time constant not given.
Maximum continuous power not given.
Speed feedback configuration has
changed.
What to do
•
Check that parameter
Temperature 1 source
Temperature 2 source
corresponds to actual encoder
interface installation.
Check the settings of parameters
91.21
and 91.24. Check that the
corresponding module is activated
in parameters 91.11...91.14. Use
parameter
91.10 Encoder
parameter refresh
changes in the settings.
•
FEN-01 does not support
temperature measurement with
KTY sensor. Use PTC sensor or
other encoder interface module.
Check for overloaded motor.
Adjust the parameters used for the motor
overload function (35.51...35.53) and
35.55...35.56.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
Stop drive. Let resistor cool down.
43.12
Check resistor overload protection
function settings (parameter group
Brake
chopper).
Check warning limit setting, parameter
43.12 Brake resistor warning
Check that the resistor has been
dimensioned correctly.
Check that braking cycle meets allowed
limits.
One or more of the resistor data settings
(parameters 43.8...43.10) is incorrect.
The parameter is specified by the
auxiliary code.
Check value of 43.10.
Check value of 43.8.
Check value of 43.9.
Check the auxiliary code (format XXYY
ZZZZ). "XX" specifies the number of the
encoder interface module (01:
91.11/91.12, 02: 91.13/91.14, "YY"
specifies the encoder (01:
configuration, 02:
configuration). "ZZZZ" indicates the
problem (see actions for each code
below).
