The default value of the parameter is 0: PU data value.
4.4.23.3 Increased minimum switch-off time in case of errors
For errors that cause stress to the inverter, hardware-related pauses must be ob-
served independent of the parameterized minimum switch-off time.
These errors are: OC, OP, OP2, OL2
Minimum switch-off time after first error (or after 2 minutes without error)
=> 50ms
Minimum switch-off time for the next 4 errors within the monitoring interval of 2
minutes: => The value defined in the power unit data for the minimum switch-off
time.
A counter increments with each error. The error counter is reset when this error
has not occurred for 2 minutes.
In order to avoid frequent repetition of the same error, the release of the modula-
tion is rejected for a longer time if a counter of category (OC, OP / OP2, OL2)
reaches the error level 6. The minimum switch-off time changes then to 2 minutes.
Minimum switch-off time for 6 errors within the monitoring interval of 2 minutes: =>
2 Minutes
After 2 minutes without error, the device is regarded again as "unloaded" and the
short protection time for the initial error becomes effective again.
4.4.23.4 Display minimum switch-off time / protection time active
The protection times after the occurrence of an error and the "standard" minimum
switch-off time have the same effect: they prevent the activation of the modulation.
If it is tried to set the drive into the state "operation enabled" while the minimum
switch-off time is still running, the drive is set to "Mod off pause active" instead.
If it is tried to set the drive into the state "operation enabled" while the guard time is
running, the drive is set to "protection time active" instead.
by exceeding the permissible number of errors within the monitoring
interval of 2 minutes, the activation of the modulation was perma-
nently prevented. Restart is only possible by switching off the 24V
supply or the high voltage.
