Leveling overtime stop
This function generates an emergency stop signal (OFF3) if the time the elevator
travels at the leveling speed exceeds the time defined with parameter 81.09 LVL MAX
TIME. With this function, possible damage to the elevator system can be avoided in
situations where the stop command is not received on time after the leveling
command due to an electrical or mechanical problem.
The function is enabled when 81.09 LVL MAX TIME is > 0.

Diagnostics
Thermal motor protection
With parameters 46.07 ... 46.10, you can set up motor overtemperature protection
and configure motor temperature measurement (if present).
The motor can be protected against overheating by measuring the motor temperature
with PTC or KTY84 sensors.
Temperature sensors
It is possible to detect motor overtemperature by connecting a motor temperature
sensor to thermistor input TH of the drive or to optional encoder interface module
FEN-xx.
Constant current is fed through the sensor. The resistance of the sensor increases as
the motor temperature rises over the sensor reference temperature Tref, as does the
voltage over the resistor. The temperature measurement function reads the voltage
and converts it into ohms.
Parameters Additional information
81.09 LVL MAX TIME Defines the maximum time the drive can run at the leveling speed.
Alarms Additional information
LVL TIME OVER Leveling overtime stop function is activated during the last run.
