Description of Function Codes
It is used to select the setting channel of the main frequency. You can set the main
frequency in the following 10 channels:
•
0: Digital setting (non-retentive at power failure)
The initial value of the set frequency is the value of P0-08 (Preset frequency). You can
change the set frequency by pressing
the UP/DOWN function of input terminals).
When the AC drive is powered on again after power failure, the set frequency reverts to
the value of P0-08.
•
1: Digital setting (retentive at power failure)
The initial value of the set frequency is the value of P0-08 (Preset frequency). You can
change the set frequency by pressing keys
using the UP/DOWN function of input terminals).
When the AC drive is powered on again after power failure, the set frequency is the
value memorized at the moment of the last power failure.
Note that P0-23 (Retentive of digital setting frequency upon power failure) determines
whether the set frequency is memorized or cleared when the AC drive stops. It is
related to stop rather than power failure.

2: AI1 (0–10 V voltage input)
•
3: AI2 (0–10 V voltage input or 4–20 mA current input, determined by jumper J8)
•
4: AI3 (0–10 V voltage input)
The frequency is set by analog input. The I5300 control board provides two analog
input (AI) terminals (AI1, AI2). Another AI terminal (AI3) is provided by the I/O extension
card.
The I5300 provides fve curves indicating the mapping relationship between the input
voltage of AI1, AI2 and AI3 and the target frequency, three of which are linear (point-
point) correspondence and two of which are four-point correspondence curves. You can
set the curves by using function codes P4-13 to P4-27 and function codes in group A6,
and select curves for AI1, AI2 and AI3 in P4-33.
When AI is used as the frequency setting source, the corresponding value 100% of the
voltage/current input corresponds to the value of P0-10 (Maximum frequency).
•
5: Pulse setting (DI5)
The frequency is set by DI5 (high-speed pulse). The signal specification of pulse setting
is 9–30 V (voltage range) and 0–100 kHz (frequency range). The corresponding value
100% of pulse setting corresponds to the value of P0-10 (Maximum frequency).
•
6: Multi-reference
In multi-reference mode, combinations of different DI terminal states correspond to
different set frequencies. The I5300 supports a maximum of 16 speeds implemented
by 16 state combinations of four DI terminals (allocated with functions 12 to 15)
in Group PC. The multiple references indicate percentages of the value of P0-10
(Maximum frequency).
