Thermal monitoring
The purpose of thermal monitoring is to detect critical states. Parameterizable warning
thresholds are available that allow further operation of the drive (e.g. with reduced power)
and prevent an immediate shutdown. However, the parameter assignment options are only
interventions below the shutdown thresholds.
The following thermal monitoring options are available:
● Motor
– Motor I
2
t model
● Braking resistor
– Temperature model
● Power end stage
– Overload protection
– Temperature sensor
When an overload is detected by one of these monitoring functions, a warning is output first.
The respective warning thresholds (p0291) are parameterizable. The current status of the
monitoring functions is displayed. If an alarm or fault limit is exceeded, the "Temperature
monitoring" message is sent.
Note
All alarm and fault limits are provided with a corresponding hysteresis. The corresponding
alarm or fault mess
ages therefore remain until the threshold including hysteresis has been
fallen below.
Note
Motor and brake resistance values
The thermal motor and braking resistor values are calculated values. The values are not
saved.
After a pow
er reset, the values only match again after a sufficiently long cooling time.
Operating temperature
Note that the specified ambient temperature range for the drive must always be adhered to,
see section Technical specifications of the ET 200SP F-TM ServoDrive (Page 97).
