Figure 6.83 Frequency Command Loss Detection Operation
This parameter sets the drive operation when a frequency command loss is detected. Set
E2-00 to E2-03 to 9 (Frequency Command Loss) for the output terminal to trigger when
frequency command loss occurs.
Frequency Command Loss Detection Selection
0 : Drive stop
The drive runs according to the frequency command.
1 : Continue operation according to the setting in P4-03.
The drive continues to run at the frequency set to P4-03 during frequency command loss.
When the frequency command is restored, the operation will be continued with the frequency
command.
P4-03 Frequency Command at Frequency Command Loss
Sets the frequency command level at which the drive runs when detecting a frequency
command loss and when L4-02 is set to 1. Sets the value as a percentage of the maximum
output frequency set in d1-02.

P4-04 Frequency Command Loss Detection Time
When the frequency command falls below 90% of the command within this detection time, the
frequency command loss will be detected.
