Parameter Descriptions
SPEED FBK RPM
PREF: 70.04 Default: —.xx rpm Range: —.xx rpm
This parameter changes according to the CONTROL MODE (MOTOR DATA function block):
• In CLOSED-LOOP VEC mode the parameter shows the mechanical speed of the motor shaft in revolutions per minute as
calculated from the speed feedback device.
• In SENSORLESS VEC mode the parameter shows the calculated mechanical speed of the motor shaft in revolutions per
minute.
• In VOLTS/Hz mode the parameter shows motor synchronous speed in rpm.
SPEED FBK REV/S
PREF: 70.05 Default: —.xx rev/s Range: —.xx rev/s
This parameter changes according to the CONTROL MODE (MOTOR DATA function block):
• In CLOSED-LOOP VEC mode the parameter shows the mechanical speed of the motor shaft in revolutions per second as
calculated from the motor speed feedback.
• In SENSORLESS VEC mode the parameter shows the calculated mechanical speed of the motor shaft in revolutions per
second.
• In VOLTS / Hz mode, the parameter shows the motor synchronous speed in revolutions per second.
SPEED FBK %
PREF: 70.06 Default: —.xx % Range: —.xx %
This parameter changes according to the CONTROL MODE (MOTOR DATA function block):
• In CLOSED-LOOP VEC mode the parameter shows the mechanical speed of the motor shaft as a percentage of the user
maximum speed setting (MAX SPEED in the REFERENCE function block) as calculated from the motor speed feedback.
• In SENSORLESS VEC mode the parameter shows the calculated mechanical speed of the motor shaft as a percentage of
the user maximum speed setting (MAX SPEED in the REFERENCE function block).
• In VOLTS / Hz mode, the parameter shows the electrical drive output frequency as a percentage of the user maximum
speed setting (MAX SPEED in the REFERENCE function block).
