• For special-purpose motors, enter the correct data to all E5 parameters according to the Test Report
provided for the motor.
Load is too heavy.
• Increase the value set to n8-55 (Load Inertia for PM).
• Increase the value set to n8-51 (Pull-In Current during Accel/Decel for PM).
• Reduce the load.
• Increase the motor or drive capacity.
Load inertia is too heavy. Increase n8-55 (Load Inertia for PM).
Acceleration and deceleration times are too
short.
• Increase the acceleration and deceleration times (C1-01 through C1-08).
• Increase the S-curve acceleration and deceleration times (C2-01).
