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 torque control is active, or
– 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
may be activated if the control signal is lost. Refer to parameter 3001
and parameter 3002
