Setting the Control Method
Any
of the following three control methods can be set.
• V/f
control without PG (normal speed control)
•
V/f
control with PG (simple speed feedback control)
•
Open-loop
vector control (high-performance control without PG)
V/f Control without PG (A1-02 = 0)
• Set
either one of the fixed patterns (0 to E) in E1-03 (V/f Pattern Selection) or set F in E1-03 to specify a
user-set
pattern as required for the motor and load characteristics in E1-04 to E1-13 in advanced program-
ming
mode.
• Perform
stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for
the
actual installation or the load is heavy enough to produce stalling. Refer to the following section on
Autotuning
for details on stationary autotuning.
V/f Control with PG (A1-02=1)
•
Set
either one of the fixed patterns (0 to E) in E1-03 (V/f Pattern Selection) or set F in E1-03 to specify a
user-set
pattern as required for the motor and load characteristics in E1-04 to E1-13 in advanced program-
ming
mode.
•
Set
the number of motor poles in E2-04 (Number of Motor Poles)
• Set
the number of rotations per pulse in F1-01 (PG Constant). If there is a reduction gear between the
motor
and PG, set the reduction ratio in F1-12 and F1-13 in advanced programming mode.
• Perform
stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for
the
actual installation or the load is heavy enough to produce stalling. Refer to the following section on
Autotuning
for details on stationary autotuning.
Open-loop Vector Control (A1-02 = 2)
Perform
autotuning. If the motor can be operated without a load, perform rotational autotuning. If the motor
cannot
be operated, perform stationary autotuning. Refer to the following section on Autotuning for details on
autotuning.
Simple
operation of a general-purpose
motor
at 50 Hz:
E1-03
= 0
Simple
operation of a general-purpose
motor
at 60 Hz:
E1-03
= F (default) or 1
If
E1-03 = F, the default setting in the user setting from
E1-04
to E1-13 are for 60 Hz (50 Hz for -E models)
