Speed Control (Without Encoder); Outline Of Speed Control - Mitsubishi Electric FR-V560 Instruction Manual

Speed control (without encoder)

This inverter can control a motor under speed or torque control. (As required, set "1" (extended function parameters
valid) in Pr. 160 "extended function selection".)
Refer to page 163 for details of Pr. 160 "extended function selection". (Since the factory setting of Pr. 77 is "0",
perform parameter write in the PU mode or during a stop.)

3.1 Speed control (without encoder)

3.1.1

Outline of speed control

The basics of speed control are explained in the Instruction Manual (basic).
Set either of "10 (speed control) or 12 (speed-torque switchover)" in Pr. 800 "control system selection" to make
speed control valid.
Pr. 800 is factory-set to 0 (speed control, vector control with encoder) (Refer to page 182.)
Perform online auto tuuning. (start time tuning) (Refer to the Instruction Manual (basic).)
As required
(1) Gain adjustment
1) Perform easy gain tuning (Pr.819=2). (Refer to the Instruction Manual (basic).)
2) Perform speed feed forward control. (Refer to page72)
3) Perform manual input gain adjustment. (Refer to page 70)
(2) Set the torque restriction value.
For details of connection diagram, test run, and easy gain tuning, refer to the
Instruction Manual (basic).
Set the motor. (Refer to page 8.)
Perform offline auto tuuning.(Refer to page 132.)
Set the operation command. (Refer to page 129.)
Test run
To achieve faster responsiveness to the speed com-
mand change (when faster responsiveness is desired)
For further fine adjustment of gains.
