Parameters
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-Fan Alternation) is active.
Note: Parameter 1208
CONST SPEED
7 acts also as a so-called fault speed which
may be activated if the control signal is lost. For example, see parameters 3001
