9.3 Monitoring
Various monitoring functions protect the drive from impermissible operating conditions.
If a monitoring function is activated,
z a reaction to protect the drive will be activated (configuration (

9-220)).
z a digital output is set if it is assigned to the corresponding reaction.
z the fault message is entered at the first position in the history buffer. (

9.3.1 Reactions
According to the interferences one or several of the following reactions are possible via the
monitoring function:
Reaction Effects on drive or controller Danger notes
TRIP
(highest priority)
• Switches the power outputs U, V, W to a high resistance until TRIP is
reset
• The drive is idling (no control!).
• After TRIP reset the drive accelerates to its setpoint along the set ramps.
(

10-10)
Message
• Switches the power outputs U, V, W to a high resistance as long as the
message is active.

• Short-time
message
≤
0.5 s
The drive is idling (no control!) as long as the message is
active
If the message is removed, the drive accelerates to its
setpoint with maximum torque.

The drive restarts automatically if the
message is removed.
• Long-term
message
> 0.5 s
The drive is idling (because of internal controller inhibit!)
as long as the message is active.
If necessary, restart positioning program.
Warning
• Only display of the operating fault
• The drive operates under control.

Off • No reaction to operating faults! Monitoring is deactivated.

Since these reactions have no effect on the
drive behaviour, the drive may be destroyed.
