n C1-01 to C1-08: Accel, Decel Times 1 to 4Four different sets of acceleration and deceleration times can be set in the drive by digital inputs, motor selection, or switchedautomatically.Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency (E1-04).Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. C1-01 and C1-02are the default active accel/decel settings.No. Parameter Name Setting Range DefaultC1-01 Acceleration Time 10.0 to 6000.0 s <1> 10.0 sC1-02 Deceleration Time 1C1-03 Acceleration Time 2C1-04 Deceleration Time 2C1-05 Acceleration Time 3 (Motor 2 Accel Time 1)C1-06 Deceleration Time 3 (Motor 2 Decel Time 1)C1-07 Acceleration Time 4 (Motor 2 Accel Time 2)C1-08 Deceleration Time 4 (Motor 2 Accel Time 2)<1> The setting range for the acceleration and deceleration times is determined by the accel/decel time setting units in C1-10. For example, if the timeis set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.Switching Acceleration Times by Digital InputAccel/decel times 1 are active by default if no input is set. Activate accel/decel times 2, 3, and 4 by digital inputs(H1-oo = 7 and 1A) as explained in Table 4.8.Table 4.8 Accel/Decel Time Selection by Digital InputAccel/Decel Time Sel. 1H1-oo = 7 Accel/Decel Time Sel. 2H1-oo = 1AActive TimesAcceleration Deceleration0 0 C1-01 C1-021 0 C1-03 C1-040 1 C1-05 C1-061 1 C1-07 C1-08Figure 4.18 shows an operation example for changing accel/decel. times.

Accel/decel times 1 and 2 canbe switched for each motor using a digital inputs set to H1-oo = 7 like shown in Table 4.9.Note: 1. The motor 2 selection function cannot be used with PM motors.2. Attempting to use the digital input setting “Accel/Decel time 2 selection” (H1-oo = 1A) together with motor 1/2 switching triggers anoPE03 error, indicating contradictory multifunction input settings.4.6 Basic Drive Setup AdjustmentsYASKAWA ELECTRIC TOEP C710616 41B YASKAWA AC Drive - A1000 Quick Start Guide 954 Start-Up Programming& Operation
