The day of the week displayed in Pr 6.18 is zero unless Pr 0.24 is set to
1, 2 or 3.
To adjust the date/time, set Pr 0.24 to 5. Enter date/time in Pr 0.22 and
Pr 0.23. The date/time will be written to the internal real time clock and
any Solutions Module installed that supports real time clock functions.
The drive date and time (Pr 0.22 and Pr 0.23) are used for the date/times
associated with the trip log (Pr 10.41 to Pr 10.60) and timer functions
(Pr 0.52 to Pr 0.58).
If Pr 0.24 is changed, then a reset must be initiated for the change to
take place, otherwise the originally selected clock will be used for the trip
log and timer functions.
If Pr 0.24 is changed and a reset is initiated then the trip log times are
cleared and the repeat period for the timers (Pr 0.56) set to zero,
disabling the timers.
Daylight saving time is enabled if Pr 0.25 is set to 1 (Std) or 3 (US) and
has the following effect:
6.2.12 Low load
The low load detection function is enabled if Pr 0.26 is set to a non zero
value. It is activated when the load (Pr 4.20) falls below the value set in
Pr 0.26, if the frequency/speed is above the value set in Pr 0.27 and the
motor is not accelerating or decelerating i.e. "At Speed" parameter
(Pr 10.06) is set to one. When activated, a 'Load' warning message is
displayed if Pr 0.28 is set to zero, otherwise a 'Load' drive trip is initiated.
When low load is detected, Pr 10.61 changes to On (1).
6.2.13 SMARTCARD
This parameter shows the number of the data block last transferred from
a SMARTCARD to the drive.
* Modes 1 and 2 are not user saved, Modes 0, 3 and 4 are user saved.
N
If Pr 0.30 is equal to 1 or 2 this value is not transferred to the EEPROM
or the drive. If Pr 0.30 is set to a 3 or 4 the value is transferred.
For further information, please refer to Chapter 9 SMARTCARD
operation on page 129.
6.2.14 Drive parameters
Pr 0.31 indicates the voltage rating of the drive.
Pr 0.32 indicates the drive current scaling.
Open-loop
When the drive is enabled with Pr 0.33 = 0, the output frequency starts at
zero and ramps to the required reference. When the drive is enabled
when Pr 0.33 has a non-zero value, the drive performs a start-up test to
determine the motor speed and then sets the initial output frequency to
the synchronous frequency of the motor. Restrictions may be placed on
the frequencies detected by the drive as follows:
RFC
When the drive is enabled with this bit at zero, the post ramp reference
(Pr 2.01) starts at zero and ramps to the required reference. When the
drive is enabled with this bit at one the post ramp reference is set to the
motor speed.
If catch a spinning motor is not required, this parameter should be set to
zero as this avoids unwanted movement of the motor shaft when zero
speed is required. With larger motors it may be necessary to increase
Pr 5.40 Spin Start Boost from its default value of 1.0 for the drive to
successfully detect the motor speed.
