Table A.1 Parameter List (Continued)
Description
Sets the amount of time for a filter on the output of the PI
controller.
Determines whether the PI controller will be direct or reverse
acting.
0: Normal Output (direct acting)
1: Reverse Output (reverse acting)
Sets the output gain of the PI controller.
0: 0 limit (when PI output goes negative Drive stops)
1: Reverse (when PI goes negative Drive reverses)
0 limit automatic when reverse prohibit is selected using b1-04
0: Disabled
1: Alarm
2: Fault
Sets the PI feedback loss detection level as a percentage of
maximum frequency (E1-04).
Sets the PI feedback loss detection delay time in terms of seconds.
Sets the sleep function start frequency.
Sets the sleep function delay time in terms of seconds.
Applies an accel/decel time to the PI setpoint reference.
0: Disabled
1: Enabled
*Depends on b5-20.
Set display/setting unit of b5-19, U1-24, and U1-38.
Input Source Selection for Sleep function Mode.
0: PI Setpoint
1: SFS Input (This is near the PI Output)
2: Snooze
Sets the PI snooze function start level as a percentage of maximum
frequency (E1-04).
Sets the PI snooze function delay time in terms of seconds.
When the PI feedback drops below this level, normal PI operation
starts again. Set as a percentage of maximum frequency (E1-04).
Temporary increase of PI setpoint to create an overshoot of the
intended PI setpoint.
Sets a time limitation for reaching temporarily boosted PI setpoint
(intended PI setpoint + b5-25).
PI snooze mode will be activated when PI feedback is above this
level. Set as a percentage of maximum frequency (E1-04).
