Note 2: F5001 does not apply to the setting of
action and control characteristics cannot be guaranteed where the F5001's setting does not match ratings of the connected
motor.
Note 3: In the speed sensorless vector control mode, motor parameters, control frequency and voltage are used to drive the motor,
therefore control characteristics depend on motor parameters, and the best performance may not be achieved depending on
the motor. If motor characteristics, etc. are not mastered, auto measurement of motor constant shall be carried out using
auto tuning, and, the use of V / f mode of which the control characteristics do not depend on motor parameters is
recommended for control.
Note 4: When setting speed sensorless vector control mode, the following function codes shall be limited.
F1004 — F1008: setting inactive
F1102 (Starting mode) =3 (started by starting frequency after DC braking): setting inactive. Starting excitation shall be
made by setting starting excitation time (F6006), and then the operation shall be started by starting frequency according to
the setting values of operation starting frequency (F1104) and starting delay time (F1105).
F1103 (starting frequency): Although the setting is active, the minimum value is 0.2Hz in speed sensorless vector control
mode.
F1111 (braking mode) =2: setting inactive. Braking excitation is made according to the setting of braking excitation time
(F6008) when stopped. The relation between output frequency and the settings of F1104 and F1112 is handled in the same
way with V / f mode.
F1113, F1114: Changed to F6007, F6008 for DC braking function.
F1701, F1703: Changed to F6001, F6003 for current limiting.
Note 5: Others
1 Upper frequency limit (F1007) sets the motor's rated speed as the synchronous speed, please set the frequency specified by
the motor's number of poles as the maximum value of frequency setting. The operation is a weak magnetic-controlled
constant power operation where the frequency setting values above rated frequency (F5003) are used to drive motor,
however, do not set the upper frequency limit too much higher than the rated frequency as it may cause mechanical damage
to the motor.
2 When output is stable, because the motor's speed is controlled to keep it constant, the frequency that the inverter actually
outputs constantly changes. In contrast to the case of the V/f mode, the set frequency and the output frequency do not
necessarily coincide when output is stable. Therefore, the output frequency may exceed the set frequency.
3 "Frequency arrival" and "frequency matching" set by F1509 — F1511 determine when the output frequency reaches or
matches the set frequency. Therefore, for the "frequency matching" function, set the frequency matching range (F1508) to a
few Hz because of the reason described in
4 All values output to the operation panel's 7-segment monitor are based on the output frequency. In the frequency display
mode, the output frequency is displayed. In case of speed and no-units display, estimated speed is displayed in speed
sensorless vector control; and detected speed is displayed in speed sensor vector control.
5 In the use of speed sensor vector control mode, please correctly configure the basic settings of PG sensor. The motor can
not be normally controlled if incorrectly configured
② and ③ in Note 1, please s et it correctly according to the above. And, the inverter
