Figure 2.27 Time Chart for the Dwell Function at Start/Stop
■ b6-01: Dwell Reference at Start
No.
(Hex.)
Name Description
Default
(Range)
b6-01
(01B6)
Dwell Reference at Start
Sets the output frequency that the drive will hold momentarily when the motor starts.
0.0
(Determined by A1-02)
When the drive accelerates to the output frequency set in b6-01, it holds that frequency for the time set in b6-02
[Dwell Time at Start], and starts to accelerate again.
■ b6-02: Dwell Time at Start
No.
(Hex.)
Name Description
Default
(Range)
b6-02
(01B7)
Dwell Time at Start
Sets the length of time that the drive will hold the output frequency when the motor starts.
0.0 s
(0.0 - 10.0 s)
■ b6-03: Dwell Reference at Stop
No.
(Hex.)
Name Description
Default
(Range)
b6-03
(01B8)
Dwell Reference at Stop
Sets the output frequency that the drive will hold momentarily when ramping to stop the motor.
0.0
(Determined by A1-02)
When the drive decelerates to the output frequency set in b6-03, it holds that frequency for the time set in b6-04
[Dwell Time at Stop] and starts to decelerate again.
■ b6-04: Dwell Time at Stop
No.
(Hex.)
Name Description
Default
(Range)
b6-04
(01B9)
Dwell Time at Stop
Sets the length of time for the drive to hold the output frequency when ramping to stop the motor.
0.0 s
(0.0 - 10.0 s)
◆ b8: Energy Saving
Energy-saving control improves overall system operating efficiency by operating the motor at its most efficient level.
Set b8-01 and these parameters according to the control method and the motor.
• When you use V/f Control, set parameters b8-04 to b8-06.
• When you use vector control with an induction motor, set parameters b8-02 and b8-03.
• When you use a PM motor, set parameters b8-16 and b8-17.
Note:
• Energy-saving control is not appropriate for applications with sudden changes in the load, or applications driving heavy loads such as a
traverse car application.
• Energy-saving control maximizes operation based on precise motor data set to the drive. Make sure that you do Auto-Tuning and enter the
correct information about the motor before you use the Energy-saving control.
