Parameters
Description
Upper limit
Upper limit - error If the current exceeds this value, an error is generated and,
depending on the parameter, an internal trip command may or may
not be generated. The parameter value "0" deactivates the
monitoring of the limit value.
• Factory setting: 0%
• Setting range: 50 ... 400 %
• Increment: 1%
Upper limit - maintenance
demanded
If the current exceeds this value, a warning is generated. The
parameter value "0" deactivates the monitoring of the limit value.
• Factory setting: 0%
• Setting range: 50 ... 400 %
• Increment: 1%
Response to error
Do not turn off
(factory setting)
On exceeding the "upper limit - error" the motor is not turned off.
Turn off
On exceeding the "upper limit - error" the motor is turned off.
Lower limit
Lower limit - error The currently measured current value is checked against this limit
value. If the value falls below this limit, an error is generated and,
depending on the parameter, an internal trip command may or may
not be generated. The parameter value "0" deactivates the
monitoring of the limit value.
• Factory setting: 0%
• Setting range: 19 ... 100%
• Increment: 1%
Lower limit - maintenance
demanded
The currently measured current value is checked against this limit
value. If the speed falls below this threshold, a warning is
generated. The parameter value "0" deactivates the monitoring of
the limit value.
• Factory setting: 0%
• Setting range: 19 ... 100%
• Increment: 1%
Response to error
Do not turn off
(factory setting)
If the "lower limit - error" is undershot, the motor is not turned off.
Turn off
