Lenze EDS4900U-REG - Manual (Page 197)

Configuration
7-106 48XX/49XXSHB0399
C237 = 1
Short synchronisation fault do not result in pulse inhibit. This procedure should be
used under the conditions listed under point 2.
C237 = 2
In the event of mains failures, the synchronisation procedure sets pulse inhibit itself.
Frequency fluctuations are processed slowly. By this, blown fuses can be avoided
in the extent possible with physical measures. Only to be used with mains with fixed
frequencies, as described under point 1.
C237 = 3
Short synchronisation faults do not result in pulse inhibit. Only to be used with
mains with fixed frequencies, as described under point 1.
Changeover only when the controller is inhibited.
