This output signal is used to display whether the motor temperature (

, P1602) warning threshold.
Note:
If the motor temperature warning threshold is exceeded, initially, ”only” an appropriate signal is output.
When the warning threshold is fallen below, the signal is automatically withdrawn.
If the overtemperature remains for a time longer than that set in P1603, then an appropriate fault is
output.
The motor temperature monitoring function can be disabled/enabled using P1601.14.

Application:
The user can respond to this message by reducing the load, thereby preventing the motor from shutting
down with the ”Motor temperature exceeded” fault after the set time has elapsed.

MeldW.7
This output signal is used to display whether the temperature of the heatsink in the power module has
been exceeded.
The hardware temperature switch–in the power module cannot be parameterized.
1 signal
No heatsink temperature pre–warning
The temperature is within the permissible range.
0 signal
Heatsink temperature pre–warning
The temperature is outside the possible range.
If the excessive temperature remains, then the drive is powered down after approx. 20 s
(tripped).
