Purpose Procedure Results
Prevent overshoot. Set b5-05 [Derivative Time (D)] to a smaller
value.
Set b5-03 [Integral Time (I)] to a larger value.
Quickly stabilize control. Set b5-05 [Derivative Time (D)] to a larger
value.
Set b5-03 [Integral Time (I)] to a smaller value.
Prevent long-cycle oscillations. Set b5-03 [Integral Time (I)] to a larger value.
Prevent short-cycle oscillations. Set b5-05 [Derivative Time (D)] to a smaller
value.
If you set b5-05 = 0.00 [Derivative Time (D) =
disabling D control] and it does not stop
oscillation, then set b5-02 [Proportional Gain
(P)] to a smaller value or set b5-08 [PID
Primary Delay Time Constant] to a larger value.
EZ Sleep/Wake-up Functionality
Set b5-89 = 1 [Sleep Method Selection = EZ Sleep/Wake-up] to enable the EZ Sleep/Wake-up function.
Note:
When b5-89 = 0 [Sleep Mode Selection = Standard], the EZ Sleep function and related parameters are disabled. Parameter b5-91 [EZ
Sleep Minimum Speed] is not included in this rule.
Set b5-89 = 1 to disable b5-15 [PID Sleep Function Start Level].
Setting Parameter Description
b5-90 [EZ Sleep Unit] This parameter sets the unit of measure for b5-92 [EZ Sleep Level]. When b5-90 = 0 [0.1Hz units], the
setting range of b5-91 [EZ Sleep Minimum Speed] is 0.0 to 590.0 Hz. When b5-90 = 1 [rev/min], the setting
range is 0 to 35400 min-
-1
(r/min).
Note:
When you change b5-90, the value of b5-92 is not automatically updated.
b5-91 [EZ Sleep Minimum Speed]
Sets the output lower limit level for the PID control as Hz units or min
-1
(r/min) units.
When you use b5-91, set b5-34 = 0.0 [PID Output Lower Limit Level = 0.0 (disabled)]. When you set the
lower limit for PID output as a percentage of the Maximum Output Frequency, refer to page 535. The b5-89
setting does not have an effect.
b5-92 [EZ Sleep Level] When the output frequency or motor speed is less than the value of b5-92 for longer than the value of b5-93
[EZ Sleep Time], the drive does to sleep.
