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
Minimum Speed] is not included in this rule.
• Set b5-89 = 1 to disable b5-15 [PID Sleep Function Start Level].
