Notes
Sets the acceleration rate for all speed changes and is
dependent on inertia and acceleration torque. Also, set
parameter 422 [Current Limit 1] to drive rating.
For more information, see Acceleration Time on page
Sets the deceleration rate for all speed changes and is
dependent on inertia and deceleration torque.
Decel rate can affect the extent of the dynamic braking needed.
Increase the decel rate to reduce regenerative energy demand or
increase the dynamic brake capacity.
