OL2 Characteristics
Selection at Low
Speeds
Sets the OL2 characteristics at output
frequencies below 6 Hz.
0: No OL2 level reduction below 6Hz.
1: OL2 level is reduced linearly below 6 Hz. It
is halved at 0 Hz.

L8-40
Carrier Frequency
Reduction Time
Sets the time for that the drive continues
running with reduced carrier frequency after the
carrier reduction condition has gone (see also
L8-38).
A setting of 0.00 s disables the carrier
frequency reduction time.
