Parameter
02
-- Deceleration Time 1
Units
= Seconds
Range
= 0000 to 1600
Factory Setting = 005.0
Important: Parameter 11 must be set to 0 to allow the drive to
ramp-to-stop
This parameter determines the time that it will take the drive to decelerate
and ramp-to-stop over a 60 Hz change in frequency. From 0.5 to 0 Hz, the
accel rate is non-linear and set by either DC injection braking or the DC
dynamic brake if it is installed. From maximum output frequency to 0.5
Hz, the accel rate set by Parameter 2 will remain constant. The total time it
will take the drive to decelerate from maximum drive output frequency to
0.5 Hz is:
Total time = (Maximum Drive Output Frequency
×
Parameter 2)
÷
60.
If set to 0000, the drive will enter 40 ms but display 0000.
From 00.10-1000 seconds, this parameter sets the decel time value in 0.1
second increments.
From 1000-1600 seconds, this parameter sets the decel time value in 1
second increments.
