n b5-14: PI Feedback Low Detection Time
Sets the time that the PI feedback has to fall below b5-13 before feedback loss is detected.
No.
b5-14
n b5-15: PI Sleep Function Start Level
Sets the level that triggers PI Sleep/Snooze.
The drive goes into Sleep/Snooze mode if the PI output or frequency reference is smaller than b5-15 for longer than the time
set to b5-16. The drive resumes operation when the PI output or frequency reference is above b5-15 for longer than the time
set to b5-16.
No.
b5-15
n b5-16: PI Sleep Delay Time
Sets the delay time to activate or deactivate the PI Sleep/Snooze function.
No.
b5-16
n b5-17: PI Accel/Decel Time
The PI acceleration/deceleration time is applied on the PI setpoint value.
When the setpoint changes quickly, the normal C1-oo acceleration times reduce the responsiveness of the system as they
are applied after the PI output. The PI accel/decel time helps avoid the hunting and overshoot and undershoot that can result
from the reduced responsiveness.
The PI acceleration/deceleration time can be canceled using a digital input programmed for "PI SFS cancel" (H1-oo = 34).
No.
b5-17
n b5-18: PI Setpoint Selection
Enables or disables parameter b5-19 for PI setpoint.
No.
b5-18
Setting 0: Disabled
Parameter b5-19 is not used as the PI setpoint.
Setting 1: Enabled
Parameter b5-19 is used as PI setpoint.
n b5-19: PI Setpoint Value
Used as the PI setpoint if parameter b5-18 = 1.
No.
b5-19
Note: Unit and resolution for b5-19 is determined by b5-20 and b5-39.
Parameter b5-19 is internally limited to b5-38. Changing b5-20, b5-38 and b5-39 will not automatically update the value of
b5-19.
