What to do
Check that parameter 35.11 Temperature
1 source / 35.21 Temperature 2 source
setting corresponds to actual encoder
interface installation.
Check the settings of parameters
and 91.24. Check that the corresponding
module is activated in parameters
91.11...91.14. Use parameter
Encoder parameter refresh
any changes in the settings.
FEN-01 does not support temperature
measurement with KTY sensor. Use PTC
sensor or other encoder interface
module.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
Stop drive. Let resistor cool down.
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 43.08...43.10) is incorrect.
The parameter is specified by the
auxiliary code.
Check value of 43.10.
Check value of 43.08.
Check value of 43.09.
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: 93 Encoder 2
configuration). "ZZZZ" indicates the
problem (see actions for each code
below).
Check module location (91.12
Check the module type
against status (91.02 or 91.03).
