Configuring Inertia Compensation 7-3
▲
Set INERTIA GAIN ACCEL (P.245). Typically, this is left at its default value of 1 but
may need to be adjusted if inertia is not equal in both directions.
▲
Set INERTIA GAIN DECEL (P.229). Typically, this is left at its default value of 1 but
may need to be adjusted if inertia is not equal in both directions.
INERTIA GAIN ACCEL (P.245) and INERTIA GAIN DECEL (P.229) support the setting of
separate levels of inertia compensation for acceleration and deceleration. Typically,
the level of deceleration compensation is less than the level of acceleration
compensation because the friction load components assist the stopping torque profile.
