Description
Sets the operation method of the PI sleep function
0: Output frequency before Softstarter (SFS)
1: Frequency reference/PI target
2: Snooze
Sets the frequency level at which the snooze operation
starts as percentage of the max. output frequency.
Sets a delay timer for the snooze function
Sets the feedback level at which the inverter wakes up from
snooze operation.
Sets the PI setpoint boost when the snooze mode is acti-
vated. If it is reached once the output will be switched off.
The value is set as percentage of the PI setpoint.
Sets the maximum time the boost operation is performed.
PI Snooze function will only be activated when the feed-
back value is above this parameter setting.
The value is set as percentage of the PI setpoint.
Enables or disables the square root operation for the PI
feedback value.
0: Disabled
1: Enabled
Sets the gain for the feedback when square root operation is
enabled.
Selects whether the PI output monitor is shown as square
root value or not.
