Parameter setting procedure

1
Wiring
Perform secure wiring.
NOTE
• Do not feed the workpiece through the machine.
2
Control method selection
Select the control method according to the application and the motor.
Pr.
71 Applied motor
9 Electronic thermal O/L relay
80 Motor capacity
81 Number of motor poles
83 Rated motor voltage
84 Rated motor frequency
800 Control method selection
810 Torque limit input method selection
359 Encoder rotation direction
369 Number of encoder pulses
707 Motor inertia (integer)
724 Motor inertia (exponent)
862 Encoder option selection
∗1 For the control method, vector control is recommended.
∗2
Setting is required for a motor other than a Mitsubishi Electric motor (the SF-PR, SF-JR, SF-HR, SF-JRCA, SF-HRCA, or SF-V5RU (1500 r/min
series) motor).
NOTE
• Select Vector control method for regenerative driving in low-speed range (about 10 Hz or lower).
• For the parameter details, refer to the FR-A800 Instruction Manual (Detailed).
