Parameters
Description
Response to ON command during active mon‐
it. time
Turn off with restart
If an ON command for the motor is issued before the switching frequency
monitoring time t
1
or t
2
elapses, an error is generated and the motor is not
switched on (internal trip command). The trip is not automatically acknowl‐
edged until t
1
or t
2
elapses, and the motor is switched on when an ON com‐
mand is still present.
The trip can be bypassed using the "Emergency start" (Page 189) function. If
the emergency start function is activated in advance, the motor is switched on
despite the error message.
Turn off without restart
If an ON command for the motor is issued before the switching frequency
monitoring time t
1
or t
2
elapses, an error is generated and the motor is not
switched on (internal trip command). The trip must be acknowledged with
the "Reset" (Page 173) function.
The trip can be bypassed using the "Emergency start" (Page 189) function. If
the emergency start function is activated in advance, the motor is switched on
despite the error message.
Warning without lock-out
If an ON command is issued for the motor before switching frequency moni‐
toring time t
1
or t
2
elapses, a warning is generated and the motor is switched
on normally and not locked.
Warning with lock-out (factory setting)
If an ON command is issued for the motor before switching frequency moni‐
toring time t
1
or t
2
elapses, a warning is generated and the motor is not
switched on and locked. If an ON command is still present, the motor is not
switched on until t
1
or t
2
elapses.
Measured value "Remaining switching frequency monit. time"
If the motor cannot be switched on until t
1
or t
2
elapses, the remaining time can be displayed via
the measured value "Remaining switching frequency monit. time" (Page 227).
