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 b5-34: PID Output Lower Limit Level. 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.
|
|
b5-95 = 0 [EZ Sleep Wake-up Mode = Absolute]
|
When the PID feedback is less than the value of b5-94 [EZ Sleep Wake-up Level] for longer than the time set in b5-96 [EZ Sleep Wake-up Time], the drive restarts operation from sleep.
|
|
b5-95 = 1 [EZ Sleep Wake-up Mode = Setpoint Delta]
|
The drive resumes operation from the sleep state when the PID feedback has dropped below the value defined as the PID setpoint value minus b5-94 continuously for the time configured with b5-96.
