Control Method Type and Corresponding Features
This drive has 5 available control methods from which to select for different applications. The following table
give information about the features of each control method.
Control Method
V/f Control
(V/f)
Closed Loop V/f Control
(CL-V/f)
Notes
Controlled Motor
Induction Motor
-
Parameter Settings
A1-02 = 0
A1-02 = 1
-
Basic Control
V/f
Closed loop V/f control with
speed correction
-
Main Applications
General-purpose variable speed
control for multiple motors in
particular (applications
connecting multiple motors to a
single drive)
High-precision speed control with
encoders on machines
-
Encoder Option Card
Not necessary
Necessary (PG-B3 or PG-X3)
-
Maximum Output
Frequency
590 Hz
400 Hz

Speed Control Range
1:40
1:40
Represents the range of variable control.
(Keep increases in motor temperature in
mind when connecting and running
motors in this manner.)
Starting Torque
150% / 3 Hz
150% / 3 Hz
This is the motor torque that can be
generated at low speed during startup and
the corresponding output frequency
(rotation speed). Drive capacity must be
considered if significant torque is required
at low speed.
Auto-Tuning
Line-to-Line Resistance (usually,
not necessary)
Line-to-Line Resistance (usually,
not necessary)
Automatically tunes electrical motor
parameters.
Torque Limits
No
No
Controls maximum motor torque to
protect machines and loads.
Droop Control
No
No
Sets load torque slip for motors. Used to
distribute motor loads.
Zero Servo Control
No
No
Locks servos without an external position
controller to prevent movement caused by
external force.
