Group 12: CONSTANT SPEEDS
This group defines a set of constant speeds. In general:
•
You can program up to 7 constant speeds, ranging from
0...500 Hz or 0...30000 rpm.
•
Values must be positive (no negative speed values for
constant speeds).
•
Constant speed selections are ignored if:
- the process PID reference is followed, or
- the drive is in local control mode, or
- PFA (Pump and Fan Alternation) is active.
Note: Parameter 1208
fault speed, which may be activated if the control signal is lost.
Refer to parameter 3001
