P1300[1] : 2nd. Drive data set (DDS)
P1300[2] : 3rd. Drive data set (DDS)
Dependency:
See parameter P0205, P0500
Caution:
When commissioning Vector Control with encoder-feedback (VC), the drive should be configured for V/f
mode (see P1300) first. Run the drive and compare r0061 with r0021 that should agree in
- sign and
- magnitude (with a deviation of only a few percent).
Only if both criteria are fullfilled, change P1300 and select VC (P1300 = 21 or 23).
P0400 = 1 (single channel encoder) will only allow operation in one direction. If operation in both directions
is required, connect an encoder with 2 channels (A and B) and select setting 2. See the Operating
Instructions of the encoder module for more information.
Note:
P1300 = 1 : V/f with FCC (flux current control)
- Maintains motor flux current for improved efficiency.
- If FCC is chosen, linear V/f is active at low frequencies.
P1300 = 2 : V/f with a quadratic characteristic
- Suitable for centrifugal fans / pumps
P1300 = 3 : V/f with a programmable characteristic
- User defined characteristic (see P1320)
- For synchronous motors (e.g. SIEMOSYN motors)
P1300 = 5,6 : V/f for textil applications
- Slip compensation disabled.
- Imax controller modifies the output voltage only.
- Imax controller does not influence the output frequency.
