YES V/f
(A1-02 = 0)
Vector (A1-02 = 2 or 3) *2
Set E1-03.
V/f default: 200 V/60 Hz(400 V/60 Hz)
YES
NO
V/f Control?
Motor cable over
50 m or heavy load possibly
causing motor to stall or
overload?
Stationary Auto-Tuning for
line-to-line resistance only
Rotational Auto-Tuning *3
*1
*1 If the motor cable changes to 50 m or longer for the actual
installation, perform stationary Auto-Tuning for the line-to-line
resistance only on-site.
*2 The default control method is Open Loop Vector Control
(A1-02 = 2).
*3 If the maximum output frequency is different from the base
frequency, set the Maximum Output Frequency (E1-04) to the
value of the base frequency after Auto-Tuning.
