5.2.7 S3 Acceleration and deceleration ramp times in traveling movement application
This switch group adjusts the ramp time for motor acceleration and deceleration. The ramp time is defined as from
zero to the set maximum frequency. The acceleration and deceleration times are the same.
Contact the product’s manufacturer, if it is necessary to recalculate the ramp time.
Note: The ramp time must be set according to the wiring diagrams and parameter lists and it shall not be shortened.
Decreasing the ramp time may damage the motor brakes or the frequency converter. The ramp time can be increased, if
necessary.
