Inertia estimate
Check if the load and motor are connected correctly
Adjust accel./decel. time
The setting of accel./decel. time(Pr.01-12~Pr.01-13) can be lessened when the
current/voltage is within specification (no fault code(over current/voltage) occurs).
Pr.01-12
Accel Time 1
0.00~600.00 sec/0.00~6000.0 sec
Pr.01-13
Decel Time 1
0.00~600.00 sec/0.00~6000.0 sec
NOTE: The accel. time is the time that needs for drive to accelerate from 0.0Hz to max. operation
frequency (Pr.1-00). The decel, tome is the time that needs for drive to decelerate from max.
operation frequency (Pr.01-00) to 0.00Hz.
Inertia estimate
Setting Pr.11-00=2
Pr.11-00
System Control
bit 0: Auto tuning for ASR and APR
bit 1: Inertia estimate (only for FOCPG mode)
bit 2: Zero Servo
bit 3: Reserved
If it allows the motor to rotate in forward and reverse
<Motor can run in both forward and reverse>
After start-up the motor, observe if Pr.11-01 is convergence. After the speed is stable,
change the motor operation direction until Pr.11-01 is convergence.
<Motor can only run in one direction>
Setting multi-function input terminal to MI1=1, Pr.04-00 to 1/5 of rated frequency and the
operation frequency on the digital keypad to 4/5 of rated frequency.
Pr.04-00
1st Step Speed
Frequency
0.00~600.00Hz
Check if the setting of Pr.11-01 is convergence
When the motor runs stably,setting Pr.02-10 to 4 and check if Pr.11-01 is convergence. After
setting Pr.02-10 to 0, check if Pr.11-01 is convergence again. Please repeat above operation
until Pr.11-01 is convergence.
