Current level for Electric Motor Protection.
This parameter sets the current threshold in amps above which the Elevator
drive activates the motor overload function, described in LM08 Electric Motor
Protection.This parameter should be set in accordance with motor rated current.
For PM motors the current threshold for electronic motor protection is set equal
to the rated motor current in LM03 and therefore does not appear. Additionally,
some motors must be protected from long term peak current to prevent damage
to the motor windings. For additional settings and details, refer to LM11 Peak
Motor Current Factor.
If one of the outputs is configured as Motor Overheat warning (LO05, LO10,
LO15 or LO20) the temperature at which the warning is triggered can be set.
Unit: Degree Celsius
If the motor utilizes a KTY thermistor for temperature detection then the trigger
temperature can be set directly. In addition, the drive hardware must support
KTY a sensor.
If the motor utilizes a PTC thermistor or relay for overheat detection, then the
drive will trigger based on the thermistor resistance or open relay, and not the
temperature setting. Refer to Section 2.8 for further details on PTC tripping
and reset resistances.
