5.2 Automatic/manual mode selection
If overspeed is detected, the current paths open and the drive is switched off�
As a result the input frequency falls below the switch point and the current paths
close (below Foh)�
By means of the automatic/manual function it can be prevented that the current
paths close automatically when the input frequency drops below the Foh value�
The selection of the operating mode is made via two input terminals Y5 and Y6�
5.2.1 Automatic mode
Automatic mode
In this operating mode the device compares the input frequency with the set target
value�
• If the input frequency is below the target value, the relay outputs are switched�
• If the input frequency exceeds the target value, the relay outputs are not
switched�
The automatic operation mode is implemented by connecting input Y5 to Y1
(pulsed test signal) and input Y6 to + 24 V DC�
The device goes into the failsafe state as soon as an error has been detected
(short circuit at 0 V DC or + 24 V DC or separated connections)�
