*2 The default setting changes when the settings for C6-01 [ND/HD Duty Selection] and o2-04 [Drive KVA Selection] change.
*3 This is the setting for 200 V class drives. Multiply the voltage by 2 for 400 V class drives.
■ Elevator Start/Stop and Accel/Decel Time Shock Reduction
Shock when you start and stop the elevator and when you accelerate and decelerate is an issue for passenger
elevator applications. If shock has an effect on the quality of the ride, adjust these parameters:
■ S-Curve Characteristics, Accel & Decel Time
Adjustment Parameter Name
C1-01, C1-03, C1-05, C1-07 Accel Time 1 to Accel Time 4
C1-02, C1-04, C1-06, C1-08 Decel Time 1 to Decel Time 4
C2-01 Jerk@Start of Accel
C2-02 Jerk@End of Accel
C2-03 Jerk@Start of Decel
C2-04 Jerk@End of Decel
Figure 12.4 S-curve Characteristics, Accel & Decel Time
Note:
• When decreased operation times are necessary for the application, for example with cranes and hoists, do not use S-curve characteristic
times.
• The default setting for C2-04 [Jerk@End of Decel] will be 0.00 seconds. The default setting for other S-curve characteristics will be
0.20 seconds. Set the acceleration/deceleration times and S-curve characteristic time correctly for acceleration/deceleration start up and
end. The recommended setting of the S-curve characteristics time is 0.2 to 1.0 seconds.
• When you use the C1-11 [Ac/Dec Switch Frequency], you can switch the acceleration/deceleration rate automatically during
acceleration/deceleration. The default setting is disabled.
When the Output Frequency ≥ C1-11, operate at the acceleration and deceleration times set in C1-01 and C1-02
When the Output Frequency < C1-11, operate at the acceleration and deceleration times set in C1-07 and C1-08
• During low speed operation, if the Output Frequency < E1-09 [Min Output Frequency] in the S-Curve Time @ Start of Decel, the
drive will cancel the S-curve characteristics and do DC Inject Braking at Stop.
