Component
Type of hardware com
ponent that has triggered the fault or alarm. For "None", it is not
possible to assign the message to a hardware component.
Explanation of the message value
Explains the possible values of the placeholders (%n) in the message value. In this case,
detailed information can be speci󹪝ed regarding the cause and remedy for speci󹪝c values.
Response
Speci󹪝es the response in the event of a fault.
The following table lists all fault responses and their meanings used for the entire SINAMICS
drive family.
Table 11-6 Fault responses
List PROFIdrive Response Description
NONE – None No response when a fault occurs.
OFF1 ON/OFF Brake along the
ramp-function gen‐
erat
or deceleration
ramp followed by
pulse inhibit
Closed-loop speed control
• The motor is braked by immediately specifying n_set = 0 at the
ramp-function generator deceleration ramp (p1121).
• The pulses are suppressed when standstill has been identi󹪝ed.
• "Switching on inhibited" is activated.
Torque control
• The following applies for torque control:
Response as for OFF2.
• When switching into torque control, the following applies:
There is no dedicated braking response.
The pulses are suppressed when standstill has been identi󹪝ed.
• "Switching on inhibited" is activated.
OFF2 COASTSTOP Internal/external
pulse inhibit
Closed-loop speed and torque control
• Immediate pulse cancellation, t
he motor "coasts down " to a stand‐
still.
• "Switching on inhibited" is activated.
OFF3 QUICKSTOP Braking along the
OFF3 deceleration
ramp follo
wed by
pulse inhibit
Closed-loop speed control
• The motor is braked along the OFF3 deceleration ramp (p1135) by
immediately entering n_set = 0.
• The pulses are suppressed when standstill has been identi󹪝ed.
• "Switching on inhibited" is activated.
Torque control
• Switchover to closed-loop speed control and other responses as
described for closed-loop speed control.
STOP2 – STOP2
• The motor is braked along the OFF3 deceleration ramp (p1135) by
immediately enter
ing n_set = 0.
• The drive remains in closed-loop speed control.
ENCODER – Internal/external
pulse inhibit
The ENCODER fault response occurs because of a sensor error and
results in OFF2.
