6.5.6.4 Digital reference value reset mode
Table 31: Parameter P-24
When P-12 = 0 (control commands via terminals) and P-15 = 4, 5, or 6, the
frequency reference value can be set digitally (UP/DOWN). This digital
reference will always be automatically reset to 0 Hz (P-24 = 0) whenever the
mains voltage is disconnected, as well as every time after a stop command.
The device will then restart with the value in parameter P-02 (f-min).
By setting P-24 to 1, this reset function can be disabled. In this case, the last
reference value that is set will be stored before the device is switched off
and will automatically be used when the device is restarted. The time set in
P-03 (t-acc) will be used for the acceleration ramp.
If P-12 = 1 (or = 2), the optional DX-KEY-LED keypad can be used to control
the device and set its reference values, provided there is an enable signal at
a digital input (DI1 or DI2). The digital reference will always be automatically
reset to 0 Hz (P-24 = 0) whenever the mains voltage is disconnected, as well
as every time after a stop command, in this configuration as well. The device
will then restart with the value in parameter P-02 (f-min). Setting P-24 to 1
will disable the reset function in this case as well.
An additional option is to set parameter P-24 to a value of 2 or 3. In this case,
the keypad's START and STOP buttons will be disabled. The DE1 variable
speed starter will then respond only to commands applied to control
terminals' start start and stop commands. However, it will still be possible to
use the two arrow keys on the keypad in order to digitally set the frequency
reference value.

Starting behavior of DE1 device if the setpoint value is set
digitally (UP/DOWN) with:
The control terminals with P-12 = 0 and P-15 = 4 / 5 / 6
The keypad (optional DX-KEY-LED) with P-12 =1 or 2
Note:
If the keypad and the control terminals are used together,
the control terminals will always take priority.
Startup behaviour:
0
: Start with the value from P-02 (f-min)
1
: Start with the last setpoint value before the device was
switched off
2
: Start (Auto-r) with the value from P-02 (f-min)
3
: Start (Auto-r) with the last setpoint value before the device
was switched off
(Auto r): When this option is selected, it will only be possible to
start the DE1 device with the control terminals. The START and
STOP buttons on the keypad are disabled.
