2203 DECELER TIME 1
0.0...1800.0 s
Description
Acceleration and deceleration times
Defines the acceleration time 1, that is the time required for the speed to
change from zero to the speed defined by parameter
- If the speed reference increases faster than the set acceleration rate, the
motor speed follows the acceleration rate.
- If the speed reference increases slower than the set acceleration rate, the
motor speed follows the reference signal.
- If the acceleration time is set too short, the drive automatically prolongs the
acceleration in order not to exceed the drive operating limits.
Time
Defines the deceleration time 1, that is the time required for the speed to
change from the value defined by parameter
- If the speed reference decreases slower than the set deceleration rate, the
motor speed follows the reference signal.
- If the reference changes faster than the set deceleration rate, the motor
speed follows the deceleration rate.
- If the deceleration time is set too short, the drive automatically prolongs the
deceleration in order not to exceed drive operating limits.
If a short deceleration time is needed for a high inertia application, the drive
should be equipped a brake resistor.
