When Pr.08-27 is set as 0.00 second, the acceleration / deceleration for PID command is
disabled, PID target value equals to the PID command. When Pr.08-27 is set > 0.00 sec., the
acceleration / deceleration for PID command enables. When the PID target value changes, the
command increases and decreases according to the setting for this parameter.

For example: Set Pr.08-27 = 10.00 sec. When the PID target value changes from 0% to 100%, it
takes 10 seconds for the PID command to increase from 0% to 100%. When the PID target value
changes from 100% to 0%, it takes 10 seconds for the PID command to decrease from 100% to
0%.

When the PID allows reverse operation, and the PID output value < negative setting value, the
PID output direction changes (When setting forward command during PID operation, the PID
outputs in reverse direction; when setting reverse command, the PID outputs in forward
direction). If PID output value is > positive setting value, the output returns to the command
direction at PID's operation. This parameter needs to be used with Pr.08-21.
