Unidrive SP Advanced User Guide 127
Issue Number: 7 www.controltechniques.com
To enable the feature that indicates to the user when a filter change is due Pr 6.18 should be set to the time between filter changes. When the drive is
running, Pr 6.27 is reduced each time the runtime timer hour increments (Pr 6.23) until Pr 6.27 reaches 0, at which point Pr 6.19 is set to 1 to inform
the user that a filter change is required. When the user has changed the filter, resetting Pr 6.19 to 0 will indicate to the drive that the change has been
done and Pr 6.27 will be reloaded with the value of Pr 6.18. Pr 6.27 can be updated with the value of Pr 6.18 at any time by setting and clearing this
parameter manually.
The powered-up clock always starts at zero each time the drive is powered-up. The time can be changed by the user from the keypad, serial comms
or an application module. If the data is not written with the various parts in the correct range (i.e. minutes are greater than 59, etc.) the clock is set to
zero on the next minute. This clock may be used for time stamping the trip log if Pr 6.28 = 0.
