No motor overtemperature alarm
The temperature of the motor is within the
permissible range.
No motor overtemperature alarm
0
Alarm, motor overtemperature
The temperature of the motor is greater than the set
motor temperature threshold (p0604).
BO: r2135.14
(inverted)

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. thereby preventing the motor from shutting down with
the "Motor temperature exceeded" fault after the set time has elapsed.
1 No thermal overload in power unit alarm
The temperature of the heat sink in the power
section is within the permissible range.
7
No thermal overload in power
section alarm
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.
BO: r2135.15
(inverted)
1 The speed setpoint/actual value is within the
tolerance p2163: The signal is switched on after the
delay specified in p2167 has elapsed.
8
Speed setp - act val deviation in
tolerance t_on
0 The speed setpoint/actual value is outside the
tolerance.

1 Pulses enabled
The pulses for activating the motor are enabled.
Pulses enabled
0 Pulses inhibited
BO: r0899.11
13
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.
