The following parameters con gure the COMBIVERT Elevator Drive to the particular
motor. Correct adjustment of these parameters is critical for proper operation of the
system. Depending on the mode of operation the units and or range of acceptable
values may change. Parameters LF.10 through LF.19 have dual functions depending
on the type of motor.
For induction motor con guration modes the parameter
information will be indicated with the symbol
For synchronous permanent magnet motors, con guration mode
the parameter info will be indicated with the symbol
This parameter sets the current threshold in amps above which the
Elevator drive activates the motor overload function.
Unit: ampere
Value range: 1.0...1.1 x drive rated current
Default setting: 8.0A
Adjustment value: in accordance with motor nameplate
For PM motors the current threshold for electronic motor protection
is set equal to the rated motor current in LF.12. Some motors must
be protected from long term peak current to prevent damage to the
motor windings. This parameter is then used to limit the peak current
to the motor. If the motor current exceeds this value for longer than
3.0 seconds, the drive will automatically trigger the error E.OH2 and
shut down operation.
When adjusting the rated motor current in LF.12, this value is
automatically set to 3 times the value of LF.12. After setting LF.12,
this parameter can then be adjusted based on the max. current
allowed by the motor manufacturer.
Unit: ampere
Value range: 1.0... drive peak current
Default setting: 3 times LF.12
Adjustment value: in accordance with the motor
If this parameter is set too low, it may interfere with operation
of the elevator, resulting in shut downs.
