Communication
10.1 Communication according to PROFIdrive
Bit Meaning
Note:
When the motor temperature threshold is exceeded, only an alarm is output initially to warn you of this. The
•
alarm is canceled automatically when the temperature no longer exceeds the alarm threshold.
If the overtemperature is present for longer than the value set via p0606, a fault is output to warn you of this.
•
Motor temperature monitoring can be switched out via p0600 = 0.
•
Application:
The user can respond to this message by reducing the load. This prevents the motor from shutting down with the
"Motor temperature exceeded" fault after the set time has elapsed.
7 No thermal overload in power unit

10 Reserved
11 Controller enable
12 Drive ready
13 Pulses enabled
Application:
Armature short-circuit protection must only be switched on when the pulses are inhibited.
This signal can be evaluated as one of many conditions when armature short-circuit protection is activated.

Remarks
1 No thermal overload in power unit alarm
The temperature of the heat sink in the power unit is
within the permissible range.
0 Thermal overload in power unit alarm
The temperature of the heat sink in the power unit is
outside the permissible range.
If the overtemperature remains, the drive switches
itself off after approx. 20 s.
1 The speed setpoint/actual value is within the
tolerance p2163: The signal is switched on after the
delay specified in p2167 has elapsed.
0 The speed setpoint/actual value is outside the
tolerance.
1 ESR response initiated
0 ESR response not initiated
