Basic Programming 5 - 13
X X X X X
Digit 5 Digit 4 Digit 3 Digit 2 Digit 1
Digits 1 through 4 set the desired number to be displayed at 100% speed.
Digit 5 determines the number of decimal places
If Digit 5 =0 number format is XXXX
If Digit 5 = 1 number format is XXX.X
If Digit 5 = 2 number format is XX.XX
If Digit 5 = 3 number format is X.XXX
For example:
If b5-20=1425, then at 100% output the digital operator would display 42.5 for monitor U1-38 or U1-24.
b5-22 PI Snooze Level
b5-23 PI Snooze Delay Time
b5-24 PI Snooze Deactivation Level
The Snooze Function is a variation on the Sleep Function. The Snooze function must be selected by setting parameter
b5-21=2. Once the Snooze Function is selected, the Drive monitors the output frequency. If the output frequency drops below
the PI Snooze Level (b5-22), and stays below that level for at least the PI Snooze Delay Time (b5-23), the Drive output shuts
off.
This is different from the Sleep Function because it is the feedback that must drop below the PI Snooze Deactivation Level
(b5-24) before normal Drive output will begin again.
b5-25 PI Setpoint Boost Setting
Just before the Snooze Function is activated, the PI Setpoint can be temporarily increased to create an overshoot of the
intended PI Setpoint. The temporary boost is determined by the PI Setpoint Boost Setting (b5-25). Once the temporary boost
level is reached (or the PI Maximum Boost Time (b5-26) is exceeded), the Drive output shuts off (snoozes) and the intended PI
Setpoint returns. From this point on, the Snooze Function operates normally and the Drive output returns when the feedback
level exceeds b5-24.
b5-26 PI Maximum Boost Time
Associated with the Snooze Function. In cases where the temporary PI Setpoint (intended PI setpoint + PI Setpoint Boost)
cannot be reached within the PI Maximum Boost Time (b5-26), the Setpoint Boost is interrupted and the Drive output is turned
off.
