Dependency: Refer to: r0034, p0612, r0632
Refer to: F07011, A07012, A07910
Note: For bit 00, 04:
The motor temperature is measured using a temperature sensor (p0600, p0601). When the bit is set, a high
temperature is identified, and a corresponding signal is additionally output.
For bit 01, 05:
The motor temperature is monitored based on a temperature model (p0612). When the bit is set, a high temperature
is identified, and a corresponding signal is additionally output.
For bit 02:
The encoder temperature is measured using a temperature sensor. When the bit is set, a high temperature is
identified, and a corresponding signal is additionally output.
For bit 08:
When reaching the motor temperature alarm threshold, reduction of the maximum current is set as response (p0610
= 1). When the bit is set, reduction of the maximum current is active.

Unit group: 21_1
Min
0.0 [°C]
Description: Sets the alarm threshold for monitoring the motor temperature for motor temperature models 1 and 3.
The stator winding temperature (r0632) is used to initiate the signal.
The following applies for temperature model 1 (I2t):
- only effective from firmware version 4.7 SP6 and p0612.8 = 1.
- Alarm A07012 is output after the alarm threshold is exceeded.
- when commissioning a catalog motor for the first time, the threshold value is copied from p0605 to p5390.
The following applies for temperature model 3:
- after the alarm threshold is exceeded, alarm A07012 is output and a calculated delay time (t = p5371/p5381) is
started.
- if the delay time has expired and the alarm threshold has, in the meantime, not been fallen below, then fault F07011
is output.
Dependency: Refer to: r0034, p0605, p0612, r0632, p5391
Refer to: F07011, A07012, A07014
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The hysteresis is 2 K.
