0: Disabled
1: Enabled (PID output becomes output frequency reference,
deviation D controlled)
2: Enabled (PID output becomes output frequency reference,
feedback D controlled)
3: Enabled (PID output added to frequency reference, deviation
D controlled)
4: Enabled (PID output added to frequency reference, feedback
D controlled)
5: Mode compatible with setting 1 of similar products from a
previous product line
6: Mode compatible with setting 2 of similar products from a
previous product line
7: Mode compatible with setting 3 of similar products from a
previous product line
8: Mode compatible with setting 4 of similar products from a
previous product line
Note: 1. If the drive is replaced with Varispeed F7
drive or a similar product from a previous
product line, use settings 5 to 8 instead of
settings 1 to 4.
2. Settings 5 to 8 are not available in models
4A0930 and 4A1200.
