Acceleration/Deceleration: C1-01 To C1-04 - YASKAWA CIMR-JC4A0002BAA Quick Start Manual

n
Coast to Stop: b1-03 = 1
When the run command is removed, the drive will shut off its output and the motor will coast
(uncontrolled deceleration). The motor will coast to a stop at the rate determined by the load
inertia.

Note: 1. After entering a stop command, the drive will not accept another run command until the time set
passes.
2. Do not enter another run command until the motor comes to a complete stop. If a run command must
be entered before the motor has fully stopped, use DC Injection to slow the motor or catch the motor
before restarting.

Acceleration/Deceleration: C1-01 to C1-04

C1-01 (Acceleration Time 1) sets the time to accelerate from 0 to the maximum output
frequency (E1-04). C1-02 (Deceleration Time 1) sets the time to decelerate from maximum
output frequency to 0.

WARNING! Sudden Movement Hazard. Rapid deceleration may cause the drive to fault on an overvoltage
condition, resulting in death or serious injury due to an uncontrolled motor state. Set an acceptable
deceleration time in parameter C1-09 when using the Fast-stop feature.
